More Than Monarchs – All Pollinators Need Our Attention

Milkweed is always a sellout item at our plant sales. The plight of the monarch has caught the public’s attention as few conservation efforts ever have. It is encouraging to see citizens so galvanized behind an environmental cause!
But I wonder if by focusing on one favored butterfly we aren’t seeing the bigger picture – many pollinators are in trouble, not just the cute ones. Bees, beetles, flies, moths … numerous species are in frightening decline. Even the beloved firefly is struggling. These important critters contribute to our way of life through agriculture, science, and stabilization of food webs. It is going to take more than milkweeds to help bring back our pollinator populations. Following are links to organizations and reference information that can help you be effective in the fight against pollinator loss.

Pollinators Come in All Shapes and Sizes

Ants are pollinators, wasps are pollinators …beetles and midges and even bats! Butterflies may be the most flashy and charismatic pollinator, but let’s not make it a popularity contest. If you are interested in being part of the pollinator conservation movement, be sure your efforts include multiple pollinator species.  Click here for a slideshow of pollinator facts, or here to learn about the many different species of pollinators in Kansas.

Season Long Nectar is Critical

Variety is the spice of life! Try to plant several species of wildflowers with varying bloom times, providing nectar sources that stretch through the season. Different pollinator populations peak at various times through the warm months, so provide for them by having a long blooming garden. Early spring and late fall flowers can help sustain migrating species in the difficult stages of their journey. Research from Cornell concerning east coast monarch migration suggests lack of late season nectar is more crucial to their success than milkweed. Help these insects get the energy they need all through year!

Host Plants that Work in Your Area

Want to nurse some larvae in your backyard? Find the host plants that cater to pollinators in your area. Milkweeds (Asclepias sp.) host monarch caterpillars, yes, but another plant to try is spicebush (Lindera benzoin) for the tiger swallowtail. Rattlesnake master (Eryngium yuccafolium) hosts the borer moth (Papaipema eryngii), also a favorite of wasps. Do your research before you plant to ensure that your garden will be appealing to pollinators native to your region. This link has great information on how to create pollinator habitat in the Great Plains region. This one has planting guides for US ecoregions.

Team Up With The Little Guys

We have all heard of organizations that rescue cats and dogs or save pandas from poaching. But who is looking out for the little guys? There are some wonderful organizations fighting to protect threatened species of insects and other invertebrates. Consider giving your time, talents or money to these organizations to help them carry out conservation projects. Check out their websites for helpful resources.
The Xerces Society “is a nonprofit organization that protects wildlife through the conservation of invertebrates and their habitat.” They have ongoing programs for butterfly and pollinator conservation. Monarch Watch is a nonprofit that focuses on education and conservation efforts for the monarch butterfly, based at the University of Kansas.
Pollinator Partnership is “dedicated exclusively to the protection and promotion of pollinators and their ecosystems.”

As you continue to create monarch weigh stations with proud stands of milkweed, remember that there are lots of other less popular pollinators that need our care and concern. Wasps, bees, ants and beetles may not be as beautiful as butterflies, but they too contribute to the balance of our ecosystem.

Trees For the Kansas Home

At last year’s fall plant sale I convinced my father to plant some oak trees around his house where older shade trees are nearing the end of their lives. I told him to think ahead ten years: when the sweetgum (Liquidambar styraciflua) in the front yard finally dies, won’t he wish that he had a head start on growing the next shade tree nearby? And wouldn’t it be nice to start a row of trees near his workshop to block the hot west sun? Of course! He ended up choosing a few Shumard oaks (Quercus shumardii) which have done well for him and are off to a great start.

These trees were an investment in the future of his property ownership – well placed trees can save you money on heating and cooling your home and offer protection to your roof and siding from the sun’s damaging rays. Are there parts of your yard that need a shade tree? Or perhaps you have a tree that will need replacing in the near future?

Do your research and find the perfect tree for your needs, practical and aesthetic. Following are some of my favorites from the upcoming sale, but a full list is available here.

Fruiters

If you want to add a fruiting tree to your landscape, consider a Kansas native. PawPaw (Asimina triloba) and Persimmons (Diospyros virginiana) are both delicious and underused native fruits. Both are small to medium sized trees when mature (20 to 40 feet tall) and grow well in moist to medium-dry environments.

Persimmon (left) and PawPaw (right) both produce delicious fruit.

Understory

spicebush swallowtail (Papilio troilus)

If you already have some large shade trees and want to add canopy layers, consider an under story tree that thrives in the dappled sunlight and protection of larger trees nearby.  Sassafras trees (Sassafras albidium) have unique foliage, showy spring flowers and all parts of the plant have a pleasant smell. Eastern Wahoo (Euonymous atropurpureus) is known for it’s intense fall color and often grows in a shrubby form.

Flowering

There are lots of showy flowering trees to choose from, but we carry a few particularly unique options. Hop hornbeam (Ostrya virginiana) has cream colored shrimp shaped flowers, seen below. Yellowwood (Cladrastis kentukea) trees have pendulous white blooms and bright golden fall color.

Shade

Big sturdy shade trees are a good choice for a homeowner looking to reduce their electricity bills and protect their home from the elements. Black oak (Quercus velutina) and American Chestnut (Castenea dentata) both grow upwards of 60 feet tall and both produce nuts that provide winter food for wildlife.

Planting a tree is a satisfying task — it is an investment in the years to come, the hope of growth and newness. A mature tree can even raise the market value of your home! Tree coupons for the fall plant sale (September  9 – 11) will be available soon on our website. Hope to see you at our upcoming sale, carting away a tree of your own.

A Weed By Any Other Name

Here at the Dyck Arboretum it can be a tricky task deciding what is a weed to be pulled and what should be allowed to grow on. Many of our beloved volunteers look to me for guidance when they encounter a plant that looks out of place. What is a weed here?

Many wonderful prairie plants carry the misnomer of “weed”, such as butterfly weed, iron weed, and milkweed. These are plants that may or may not need to be pulled, depending on where they are located. I consider a few factors: does the plant belong here or fit the theme of that garden bed? Is it annual or perennial?  Will it become invasive? Is it part of a plant family that is notorious for colonizing? …and so on. Weeding will become less of a guessing game when you learn to identify some native species and  particularly those nasty exotics.

While the name ‘milkweed’ might cause you to shun this plant for your garden, think before you pull! In the right area, milkweeds may be a perfect addition. They will bloom for several weeks and add a bit of important monarch habitat to your backyard. Photos from Dyck Arboretum.

 

“Where do they come from and how can I beat them?”

Just when you think you have weeded every last square inch of your garden, here they come again.  The seed bank – dormant seed that exists in the top soil – will continue to produce more weeds as long as conditions are favorable. Seeds can lay dormant in the soil for long periods of time, waiting for adequate moisture and light levels. Bindweed seed can remain viable in the soil for up to 50 years! The seed bank is created by last year’s mature weed seeds, bird droppings, hay/manure used for mulching, and seeds carried on the wind. The good news? With regular weeding and mindful practices you will decrease your weed seed bank every year. That means pulling weeds before they seed, using carefully sourced mulch material, and disturbing the soil as infrequently as possible to reduce the amount of dormant seeds awakened by light and oxygen.

Some weeds are obvious

Bindweed with it’s morning glory bloom, Siberian Elm saplings with their small serrated leaves, and prostrate spurge with its circular, flat habit all send up the red flag. These kinds of plants look out of place right away because they lack charisma and often grow in inhospitable areas. (i.e. in driveway cracks and gravel, climbing up stems of other plants).

Some weeds are ambiguous

Virginia creeper vine seems to crop up everywhere, and are very decorative if left to grow in a good spot. But they can also be aggressive when not trimmed regularly. Similarly, a mulberry sprout (which tend to come up just about everywhere a bird flies over), could be left to grow into a nice fruiting tree if you are prepared for the berry-mess and seed spread. Plants like ironweed and Illinois bundleflower seem to pop up everywhere and, though they can be aggressive spreaders, they are also quite attractive.

Ironweed (Vernonia sp.) may at first appear as an intruder, but it produces a colorful, longlasting bloom and is a favorite of swallowtails and many species of bees.

Some weeds are not weeds at all

I always advocate for leaving milkweed in the garden as habitat for monarchs. Lucky you if a few come up!  Other species like purple poppy mallow and wild petunia that may appear weedy at first actually make well behaved native specimens. These species bloom all summer long and are extremely drought tolerant.

 

While you pull and pluck away at the weeds in the garden, remember the wise words of the poet Ella Wheeler Wilcox – “A weed is but an unloved flower”. Although weeding is the tedious task all of us gardeners must endure, you can make it easier and more productive by knowing the difference between potential friend and foe.

 

 

A Tale of 3 Prairies

In the past few weeks I have had the good fortune to visit several different prairies, each under different circumstances, all of them delightful in their own way. Here’s a tale of 3 prairies for you, in hopes you become inspired to visit these places as well!

Willa Cather Memorial Prairie

Webster Co., Nebraska

Willa Cather Memorial Prairie near Red Cloud, NE.

Willa Cather Memorial Prairie near Red Cloud, NE.

I had just finished up the last few pages of Cather’s well-loved novel My Antonia as we rolled into the city of Red Cloud. A friend and I made a day trip to Webster County to take in the sights and sounds of Cather’s world, including this prairie just west of town which may have been the inspiration for some of her famous descriptions of plains life. If you are a lover of the prairie, you need to put Willa Cather’s work on your reading list immediately, then scurry up to Nebraska and tour her hometown, Red Cloud, (renamed “Black Hawk” in My Antonia) which is also the home of the Willa Cather Foundation. There you can have a personalized tour of her childhood home, church, and neighborhood along with the opera house and historic bank building, all still in turn of the century style. While hiking in her short, windy memorial prairie I saw lots of familiar species – silver sage (Artemisia ludoviciana), purple poppy mallow (Callirhoe involucrata) and little bluestem (Schizachrium scoparium).

 

Tall Grass Prairie

Chase Co., Kansas

We were far from the stage but we could hear them perfectly!

I wasn’t planning on going to the Symphony in the Flint Hills, but through the kindness of an acquaintance two tickets fell into my lap, free of charge. So with lawn chairs in tow my date and I headed out to a pasture near Clements, KS in Chase county. There was delicious BBQ to be had and an art gallery and information tent to peruse before and after the concert. The music was provided by the Kansas City Symphony; gorgeous selections were wonderfully preformed, including American folk tunes and well known tracks from Dances With Wolves and Indiana Jones. Top it all off with a live cattle drive on the hill behind the stage and the music bouncing off the hills around you, it was the perfect afternoon. The weather even cooperated – I never broke a sweat! The prairie was looking lush from recent rains; I couldn’t help but geek out on the species I recognized on the 3/4 mile walk back to the car – blue false indigo (Baptisia australis) and spider milkweed (Asclepias viridis). Save up some cash and treat yourself to this art-filled prairie experience next year!

Maxwell Wildlife Refuge

McPherson Co., Kansas

During the EPS week here at the Arboretum, I had the privilege of chauffeuring some of the participants on their field trip to Maxwell Wildlife Preserve. A good day at work, to be sure! It’s a beautiful expanse of preserved prairie that is home to Elk and Bison.

View near the Maxwell observation tower.

There were too many calves to count, perfect timing for our group.

Calf and mother stick close together.

The tour guides were charismatic and knowledgeable, providing a history of the refuge and a natural history of the land. The prairie there is healthy and diverse, giving us a look at butterfly milkweed (Asclepias tuberosa), lead plant (Amorpha canacens), goats rue (Tepherosia virginiana) and rattlesnake master (Eryngium yuccifolium).

Each prairie region has its own unique charms, from thick tall grass areas in the east to short and scrubby land in the west – Carve out some time this summer to visit and compare!

Arboretum Pond FAQ

Spring is a beautiful time to visit the Arboretum, the flowers are blooming and everything is lush and green. Unfortunately, our pond has turned green as well! The warming temperatures make perfect growing conditions for the unsightly algae and aquatic plants. Pond maintenance has become a regular part of our work week. We have been doing some quality staff bonding in the water, brainstorming together different control methods, and we have gotten many questions from passersby concerning our pond maintenance routines.

What exactly is that scummy green goop?

From left to right: moss in a Scotland bog, Spirogyra algae on a Romanian pond and an aquatic plant in an aquarium.

From left to right: moss in a Scotland bog, Spirogyra algae on a Romanian pond and an aquatic plant in an aquarium.

There seems to be much confusion when distinguishing between moss, algae and aquatic plant. Let’s set the record straight with some semi-scientific definitions:


Moss – lives mostly on land in moist/shady locations, limited vascular system to carry water and nutrients internally, which is why it is commonly small and low growing. Flowerless, seedless.

Algae – a general term encompassing many different life forms that are not all related (from single celled phytoplankton to huge clusters of seaweed/giant kelp). General definitions mention that algae lives aquatically in salt and freshwater, has

Me, sporting a wetsuit and some Ceratophyllum demersum.

varying photosynthetic pigments (red-brown algae, green-blue algae) and does not have true root systems, stems or leaves. Flowerless, seedless. 

Aquatic plant – usually has a more complex vascular system than algae or moss, lives on the surface of or suspended in water, can have prominent flowers and seeds.

Let the mystery be solved! Floating on the surface of our pond is filamentous green algae. Without taking the time to examine single cells under the microscope we can’t know the exact species, but it is likely a mixture of some of the most common North American freshwater green algae – Spirogyra, Mougeotia, and Zygnema. Just below the surface grows a thick mat of coontail (Ceratophyllum demersum), which is a free-floating aquatic plant. Stringy and clingy, it makes walking the pond a tangly chore.

What do you do about it?

Our usual method is to walk the pond with a floating board, pushing the algae and piling it up for chemical treatment. This can be a slow process and it results in large patches of smelly, rotting algae. Last week we experimented with looping the pond using a metal cable and a tractor, pulling the material to the west low-water bridge. It worked quite well, but left us with the chore of raking the globby, stringy, water-laden stuff onto the bridge to be hauled away. While it was a good staff bonding exercise, it left our backs pretty sore! Hopefully our concerted effort this spring will prevent a massive bloom later in the season, and our future maintenance will be less involved. I hope to continue a treatment regimen that is a compromise between chemical use and tiring rake work.

Is it good for anything?

While we see green growth in the pond as a nuisance, there are a few ecological benefits. Coontail plant provides habitat for perch and bass and can help settle sediment in the water. Waterfowl feed on the shoots and seeds. Free floating planktonic algae is the base of the aquatic food chain and it also can help oxygenate the water. But we just had way too much! An over growth of coontail can cause water stagnation and stunting of fish growth, and surface algae is smelly, unsightly, and shades out the habitat beneath it.

The water that supplies our pond comes from city runoff, which can unfortunately contain pollutants and unwanted nutrients from the streets and freshly fertilized yards of Hesston. An overdose of nutrients flowing into the pond, such as nitrates and phosphates, is often partially responsible for an algae bloom. As our pond ages, we will encounter new maintenance challenges: there will always be undesirable pollutants flowing in, there will always be some pesky aquatic plant to deal with. The best we can do is try to educate ourselves and attempt to be more aggressive than the algae growth!

I’ll be keeping my wetsuit hanging on the line, ready for more pond action this summer.

Katie’s Plant Picks: Mint Family

Working in the Arboretum greenhouse is a terrible temptation. I love my perennial garden at home and I never stop adding new specimens, so our selection of natives and adaptables this year is a treasure trove for me. I must truly exercise some self control to prevent my entire paycheck from turning into wildflowers. Until I win the lottery or inherit a rich uncle’s fortune, I will have to just pick a few favorites!

If you, like me, have a fond eye for every flower, then it may be helpful to guide your shopping this year by selecting a plant family to collect. Researching a scientific plant family and finding those species native to your area can help lend a theme to your garden, add cohesiveness, and curtail your wild garden spirit.

This year I am going to plant from the mint family, Lamiaceae, or formerly, Labiatae. Lucky for me, our upcoming sale has lots of gorgeous options!

Family Traits

Lamiaceae (lame-ee-ay-see-ee or lame-ee-ay-see-ii) is a large plant family with of over 3500 species. In science lingo, families are groupings of plant genera – a fancy way to say that these plants share common traits. A tell-tale sign of a mint family member is a strong aroma from the leaves, be it traditionally minty or not. These plants are some of the most valuable aromatic, culinary and medicinal crops in the world – rosemary, oregano, thyme, basil, salvia, hyssop, bee balm, and lavender are all a part of this big family.

Mint family plants commonly have square stems and flowers with bilateral symmetry (top and bottom do not match but sides mirror each other). The pictures in this post will hopefully help you to recognize some of the common traits shared among the mint family, and soon you will be identifying mint family species on your own!

Following are my top mint family picks from our plant sale, along with a list of varieties available.

My Plant Picks

One of my top picks from the mint family is agastache, commonly known as hyssop or hummingbird mint. It thrives in sun and heat and its leaves emanate a wonderfully minty scent. Its tubular flowers attract hummingbirds to the garden. We are offering it in yellow, orange, blue, violet, and pink – perfect for whatever color combination you can dream up! Blooming from early summer to late fall, agastache is a showstopper year after year in the landscape.

A. foeniculumAgastache ‘Kudos Yellow’ ‘Kudos Coral’ ‘Raspberry Summer’ ‘Summer Sunset’
‘Summer Love’ ‘Blue Boa’ ‘Violet Visions’

Salvia is another sun loving flower that I will be adding to my garden this year. Pictured above is a native variety, growing as tall as 5 feet in the right conditions. Salvias come in all shapes and sizes; mound forming, tall and showy, wispy, etc., and many different colors. Their long flowering spikes add nice movement in the breezy garden and are beloved by butterflies. The sale will have saturated deep blues and magenta available, as well as lighter tones, pink and lavender.

S. azurea ‘Grandiflora’ – S. pitcherii ‘Nekan’ – S. greggii ‘ Furman’s Red’ ‘Ultra Violet’ – S. nemerosa Violet Riot’ ‘Pink Dawn’ ‘Crystal Blue’ ‘Caradonna’ – S. macrophylla ‘Hot Lips’ ‘Windwalker Royal Red’

If you love the smell of Earl Grey tea then monarda is for you! Commonly called bee balm or wild bergamot (because of its similar fragrance to Citrus bergamia, source of earl grey tea), the leaves of this plant release their pleasant aroma every time you water or brush past. This year we are offering many different varieties of monarda, some native and others hybridized, in various shades of red and purple.

M. fistulosaM. didyma ‘Pardon My Pink’ ‘Pardon My Purple’ ‘Pardon My Cerise’ ‘Leading Lady Plum’ ‘Grape Gumball’ ‘Lilac Lolipop ‘ ‘Cotton Candy’  ‘Cherry Pops’ ‘Rockin Raspberry’

It’s hard to only pick a few when we have so many ‘minty’ options! More than just the three discussed here, we also have catmint (Nepeta sp.), Russian sage (Perovskia atriplicifolia) and lavender (Lavendula ‘Phenomenol’), and many more. If you come to the sale, you know where to find me – hovering near the mint family plants, sniffing away!

Catkins: Spring’s Botanical Wonder

Sneezing, coughing, watery eyes – everyone is complaining about allergies this time of year, the Arboretum staff included. Many people point the blame at any pretty flower they see in early spring, such as Bradford Pear blossoms (Pyrus sp.), redbuds (Cercis sp.) or daffodils (Narcissus sp.). But it is likely to be less obvious blooms causing your sniffles – catkins. The trees are chalk full of these inconspicuous, pollen-spraying fiends! I’ll have to put aside my animosity for them and their disastrous effect on my sinuses while I explain their fascinating botany…but I’ll have to blow my nose first.

Catkins

Catkins at the Arboretum now! From left to right, willow (Salix), alder (Alnus) and aspen (Populus)

Structure and Function

Catkins are flowers adapted to be pollinated by wind, which is known as anemochory. (Pollinated in water? Hydrocory. Pollinated by birds? Ornithochory. You get the idea.) Their dangling habit is part of this adaptation, and pollen is released from male flowers when wind causes them to shake. These worm-like blooms are actually hundreds of tiny flowers strung together.  Each catkin is either male or female, but both sexes may or may not be carried on the same plant. If a single plant produces both male and female catkins it is considered ‘monoecious’. Some tree and shrub species have separate sexes and produce only male or female flowers on a single plant, meaning they are ‘dioecious’.

Salix caprea flower stages – male catkin (I) and female catkin (III), ovary cross section (V)

No Beauty Queen

In general, the prettier the flower the less likely it is to be pollinated by wind. The striking white pear trees blooming now are mostly pollinated by bees, and therefore not the cause of wind-born pollen allergies. If the flower is colorful and attractive it is probably luring in winged creatures to carry it’s pollen becuase the grains are too heavy to be carried on the wind. Catkins are not burdened with the task of being beautiful – they don’t have to attract a subjective eye for pollination. But in the plant world, if you can’t be pretty then you must be prolific! These little flowers release enormous amounts of pollen onto the breeze, with little chance that any of it will serendipitously land on the female of the corresponding species. Not only does the pollen grain have to float its way to the opposite sex, but it must then land exactly on the tiny stigma, the pollen receptacle atop the female flower, to produce pollination. What a feat! With such slim odds, it is no wonder that these trees produce prodigious amounts of pollen, much to the dismay of allergy sufferers.

Whether their pollen ends up in your nose and eyes, or the catkins themselves fall wet and soggy on your windshield, try not to loathe them too much – they are just another of nature’s incredibly well-designed survival mechanisms, and all your sneezing is just a sign that spring has arrived!

Wonderful White Wildflowers

Our greenhouse is finally filling up, and what a sight! Little green sprouts are popping up in their pots, eager for more warm weather. By the time our plant sale rolls around the greenhouse will be a gallery of purple, pink and orange blooms! Unfortunately, all that gorgeous color will surely steal the spotlight away from some of my favorite white flowering species. Too many native and adaptable white wildflowers don’t get the attention they deserve in the modern garden. Opposite of the recent Oscar’s controversy, we aren’t giving these wonderful whites enough attention! White flowers add brightness to shady or green-dominated areas and won’t clash with your existing color palette.

Here are a few of my top picks from our upcoming plant sale that will add an under-celebrated species and a pop of brightness to your landscape:

Dictamnus albus – Gas Plant 

Dictamnus albus, Gas Plant - https://commons.wikimedia.org/wiki/File%3ADictamnus_albus_280506.jpg

Dictamnus albus, Gas Plant – https://commons.wikimedia.org/wiki/File%3ADictamnus_albus_280506.jpg

Dictamnus albus could be the conversation piece of your garden this year! Contrary to what its name suggests, it has a pleasant, citrus aroma when in bloom and the flowers are good for cutting. The “gas” in its common name refers to its flammable nature – the whole plant is covered with a thin layer of volatile oils that, in the right conditions, can be ignited for a brief flash of blue flame. A fun patio party trick, to be sure! These volatile oils can cause skin irritation (known as phytophotodermatitis, if you are looking to impress your friends or physician) akin to a chemical burn, a result of the oils reaction to sunlight on the skin surface. In my opinion, the beauty and intrigue are worth the small risk. Known for its longevity, it is perfect for a full sun or part shade area that is not likely to be disturbed, for the health of your epidermis and for the happiness of the plant.

 

Parthenium integrifolium – Wild Quinine

Parthenium intergrifolium, wild quinine – https://commons.wikimedia.org/wiki/File%3AParthenium-integrifolium-wild-quinine-0a.jpg

Tragically underused in today’s gardens, wild quinine blooms reliably all summer long and produces attractive seedheads for dried arrangements during fall and winter. Dreamy pearl-like flower clusters form atop serrated foliage. It thrives in full sun and isn’t preyed upon by bunnies and deer – the leaves are sandpapery and unpalatable. An attractant for equally undervalued pollinators, many species of beetles, wasps and flies flock to wild quinine to feed on its pollen and nectar. Tall and clump forming, it creates a dynamic backdrop for other, shorter flowers.

 

Ceoanthus americanus – New Jersey Tea

Ceanothus americanus, New Jersey Tea – https://commons.wikimedia.org/wiki/File%3ACeanothus_americanus.jpg (Public Domain)

A showy native shrub, New Jersey Tea grows to 3 – 4 feet tall and produces panicle shaped flower clusters in late spring to midsummer. The eastern namesake comes from its use as a surprisingly yummy tea substitute during the Revolutionary War and also utilized by Native Americans for various internal ailments*. The dense and vigorous growth habit make it difficult to transplant once established, so pick a permanent home for it in your garden. Ceaoanthus is quite tolerant of drought and poor soil, growing well in rocky, sloping areas. The Spring Azure and Summer Azure butterflies (Celastrina sp.) use New Jersey tea as their larval host plant and continue to feed on the nectar as adults. A great alternative to high maintenance, non-native shrubs.

I’ll be saving my pennies to snag a few of these beauties for my own garden, and hopefully some of you will as well. A complement to any landscape or flower arrangement and a haven for special pollinators, why shouldn’t we adore them?

Spring Garden Clean Up: Dos and Don’ts

Though we surely still have a few cold days ahead, it is clear that spring is approaching. This warm spell is bringing the birds out singing and I spy little bits of green sprouting in our clumps of native grasses. This is a sign that it is time to think about spring clean up and preparing garden beds for new growth. Here are a few guidelines that I am following as I begin to tidy up the arboretum.

DON’T …

…start your garden clean up when the ground is too soft. If the soil is still overly moist from the winter wet, you will be creating compaction everywhere you and your wheelbarrow go. If it is truly muddy, the aftermath of your foot traffic could result in uneven ground, squished or exposed roots, and new puddling areas. I know we are all itching to get outside and play in the dirt, but if your garden spot is still soaked, wait.

When cleaning up large areas of native grass, I hop on the mower and let it fly! If you are mowing your grasses, be sure to set the blades up higher than usual so you don't strip away new sprouts.

DO …

…cut back all those tall native grasses. It is nice to leave them standing through the winter to add color and interest to the winter landscape, but now is the time to shear them back, leaving only 4 to 6 inches left. Make sure to give grasses a haircut early in the spring so that the new growth doesn’t become entangled with the old, creating quite a hassle. And if you didn’t clear away all your annuals last fall, make haste! Soggy and molding annual debris is the wrong kind of compost and can lead to garden disease, providing nesting sites for microbial pests. Clear it out of there, pronto!


DON’T …

…go hacking away at your woody perennials like a maniac in an effort to neaten them up. Some species bloom on last years wood, others bloom on the current year’s wood. Before taking pruning action, do your research and ensure that you aren’t lopping off the buds of spring flowers.

Lilac (Syringa), Forsythia, Mock-orange (Philadelphus) and Beautybush (Kolkwitzia) are all woody species that should NOT be pruned in the spring because they bloom on last year’s growth. Crypemyrtle (Lagerstromeia) and Butterfly bush (Buddleia) are just the opposite – spring is the perfect time to shape them and remove split or diseased branches. These species benefit from an intense spring pruning, because it jump starts the new growth that buds are formed on.

DO …

…compost as much of your debris as possible. Turn your pain into gain and make your own organic matter to put back in the garden. But be careful – tough-to-contend-with weedy species should not be incorporated into the pile as they will likely reseed themselves. If your compost is well balanced and hot enough at its decomposing center then weed seeds don’t stand a chance … but whose compost pile is that perfect? If I am worried about the seeds of a certain plant coming back to haunt me, I just don’t take the chance.

 

DON’T stay inside, DO enjoy the outdoors! January and February is the time to make your action plan for the gardening season and when those few warm days hit, get outside and make your plans happen!

 

 

Garden Resolutions: Going Green in the New Year

In honor of the new year, you may be promising yourself to eat better, exercise more or take that dream vacation you deserve. But what about your garden? Here are 5 garden resolutions to make your yard the best it can be this year – for you and the environment!

Skip the Tilling

For gardeners, starting up the rotor tiller is part of the spring routine.
But it might not be helping the soil as much as you think!

Tilling is old news – skip the hassle this year!

Tilling thrashes through weeds for the short term, but turning the soil exposes dormant weed seeds to air and light, priming them to germinate.

Also, it can disturb earthworms and
soil bacteria that help to keep your soil aerated and healthy. Try planning out a garden that has specific foot traffic areas and beds that are easy to reach from all sides, minimizing soil compaction and the need for tilling. If you have the hardest-of-hard Kansas clay in your garden and simply must til, try working up only the rows/areas you are going to plant immediately, leaving the soil undisturbed elsewhere.

Save Water!

This year, make a resolution to lower your water bill and your environmental impact. The EPA estimates outdoor water use to be 30 percent of total household consumption. You can cut this figure by irrigating smarter and less often. If you have a sprinkler system, consider only watering in the morning hours to save water from the evaporative effects of afternoon wind and sun. You can conserve even more water by choosing a drought tolerant species of grass for your lawn – for example, a buffalo grass (Bouteloua sp.) lawn works well in Kansas and needs very little irrigation once established, even in the hottest summer months.

Collect Rainwater for Landscape Irrigation

Another way to lower your water consumption is to collect rainwater from your roof for outdoor use. Rain barrels or cisterns are simple to install and can collect run-off that would otherwise cause erosion and burden public drainage systems. There are many affordable, DIY rain collection systems that will lower your irrigation costs in the coming year. Make installation plans now so you can capture all the free water from those summer thunderstorms ahead.

Make Your Own Compost

If you haven’t been composting, make it happen this year! Compost is a great addition to hard clay soils, keeps soil organisms thriving and can serve as an alternative to chemical plant foods. The best part? It’s free! Save yourself the time of hauling away yard clippings and leaves, throw them in your compost pile instead. If you want to compost on a smaller scale, then try a compost tumbler. Some great resources regarding composting information and tumblers can be found here. You can purchase one, or make your own! 

Plant Native Species

Perhaps best way to be earth conscious in the new year is to plant your garden with native species. Ultimately, native species can give you all the benefits of the practices mentioned above: break up the soil with their deep root systems, conserve water with drought adaptations, and help balance the natural microbial activity of the soil. Of course, the Flora Kansas Spring Plant Sale April 21- 25 here at the Dyck Arboretum is the perfect place to find all the native species you need for your garden this year. 

While you are making big plans for the coming year, plan to green up your garden with some of these tips. Make it a priority this year to save time, money, and the planet!
