Winter Green

Posted on February 8, 2023 by Katie Schmidt

This time of year, I am especially thankful for my prairie garden. While the rest of the non-native and plants are looking limp and frozen, many of my prairie plants are standing tall and providing excellent color, texture and shape. Lots of native species even stay green through the coldest days of winter!

Stay Cool

For most garden plants, freezing temps are the abrupt end to the growing season. Their stems and leaves freeze, and with freezing comes the expansion of water in their cells, rupturing their delicate tissues and leaving them limp and mushy. But most popular annuals like peppers, tomatoes, petunias and marigolds, are all tropical plants not accustomed to the cold. Perennial native prairie species have a few *tricks up their leaves* when it comes to surviving the cold. To stay green and prevent cell destruction, some plants loose their leaves all together (deciduous trees and shrubs), but others change the chemical composition of their tissues in order to stay green. They load their leaves with sugar, creating a sort of anti-freeze. A leaf full of sugary solutes has a much lower freezing temp than one with regular water inside. Genius!

Care of Winter Plants

Plants that retain a bit of green all winter are a real benefit to anyone who loves to spend time in their garden regardless of the temp. But, if it’s green, its growing (albeit very slowly!). Which means those plants might need a drink of water during the long dry spells of our Kansas winter. Don’t forget to water your landscape in droughty winters, especially if they are newly planted. Check the soil with your finger by pushing it in to the second knuckle — if it’s dry, add some water. If its moist, leave it alone. Too much water in winter causes rot and death to most dryland loving natives. Manage your winter water carefully and you will be rewarded with vigorous green growth in spring!

*This dried **Vernonia fasciculata**, with its seeds dispersed from the flowers already, has little star shaped sepals left behind that look great in dried arrangments.*

If the grey, cold weather is getting you down, remember to get out in your prairie garden or visit the Arboretum to observe all the wonderful shapes, textures, and colors our native plants have to offer. Before you know it, spring will be here and we will be reminiscing about the slow, peaceful days of winter!

Seven Reasons to Attend This Years’ Luminary Walk

Posted on November 19, 2014 by Scott Vogt

Over the years, the Winter Luminary Walk at Dyck Arboretum of the Plains has become a tradition for many people. Here are my top seven reasons to be part of this unique event:

The south bridge is one of our favorite spots along the path during the luminary walk, especially on a magically snowy night. Photo by Ken Raney.

Enjoy the natural beauty of the gardens in winter. Thousands of lights bring the arboretum to life, highlighting the pure, organic forms of the trees, shrubs and prairie plants.
Relax and stroll the pathways with more than 900 jars and candles lighting the way. No commercial glitz – just the simple, soft light of candles.

Roast s’mores. Warm yourself by the fires and roast a marshmallow. Sticky fingers, but oh so good.
Drink hot almond tea with Christmas cookies in the Visitor Center. This drink is perfect on a cold winter night along with cookies from the Hesston Women’s Civic Club and other volunteers.

Walkers gather around the fire to roast marshmallows.

Make memories at the Arboretum. It is great to be with family and friends spending an evening together. Forget about the hustle and bustle of the season, slow down and enjoy together everything this time of the year has to offer.
Be creative. Each night children will make crafts that relate to a different culture’s holiday traditions.
Learn about other cultures. With the theme “Joy to the World: A Multicultural Celebration”, this year’s luminary walk will include performers, crafts, stories and an outdoor nativity representing a variety of cultural perspectives.

Stop in to the buildings to warm up and be creative during craft time.

We at the arboretum enjoy hosting this special event. It is unique because it invokes fond memories of Christmas’ past while making new memories with the special people in your lives. Come, relax, and enjoy this one-of-a-kind Christmas celebration.

Five Things You Should Do Now to Prepare for Winter

Posted on October 1, 2014 by Scott Vogt

This is my favorite time of the year. I love autumn. You can see and feel the changes of the seasons. Prairies turn from green to brilliant shades of red, orange and yellow. Trees light up the landscape with vibrant fall color. Asters dot the landscape as pollinators search for the last remaining nectar in the garden. There is so much to enjoy this time of the year. We don’t want to think about the real big change coming when winter arrives, but that change is coming all too soon.

I like to spend some time in the fall preparing our landscapes for winter. By dedicating some time now to your landscape, you will be rewarded with healthier, more beautiful plants next spring.

Here are some things on my checklist for the fall:

#1 Mulch

Fall is a great time to mulch all your plants. Mulching now will help protect roots from extreme temperatures while also helping the soils to retain moisture in a typically cold, dry winter. We apply 2-3 inches of new mulch around perennials, trees and shrubs. Be careful! Don’t allow mulch to contact the stem or trunk. We leave a halo around the plants to aid in air exchange and drying. Too much mulch can cause more harm than good.

Table Rock Maple

#2 Lawn Care

This is the best time of the year to plant a new fescue lawn or overseed an existing fescue lawn. I overseeded my back yard last week. It is just starting to germinate. I used clean, weed free seed and watered it daily. I applied 3-5 lbs. per 1000 square feet. If you are planting a new lawn, apply 5-10 lbs. per 1000 square feet. You have until October 15 to get your seeding finished. It is usually too late to seed after October 31. The cool nights, warm days, beneficial rains and less weed competition make this time of year ideal for seeding grass.

It is also the best time to fertilize your fescue lawn. We apply one pound of nitrogen per 1000 square feet. Fall fertilization promotes root growth. The roots of the fescue absorb and store the nutrients for the winter. This stored energy will make for a thicker, healthier lawn next spring.

Remove leaves from lawn and place in compost pile. Falling leaves block sunlight to the grass inhibiting growth. Leaves can be shredded and composted into the lawn, but often this causes more problems. It is usually best to completely remove them.

#3 Fall Clean-up

Remove Annuals and Cut Perennials: After the first frost, annuals can be removed from the landscape. Prior to the first hard freeze, tender annuals need to be dug up and stored for the winter (i.e. cannas and elephant ears).

In certain gardens, we deadhead spent blooms on plants such as gray-headed coneflower and coneflowers to prevent seeding. Other seedheads are left through the winter as food sources for birds. We leave ornamental grasses through the winter. They provide texture and movement in the winter landscape. These beds will be cleaned up in the spring.

Keep in mind that fall is NOT the best time to prune trees and shrubs. It encourages new growth that will not get hardened off before winter, making it susceptible to damage. Prune trees in the winter after they have gone dormant. Shrubs can be pruned in the winter as well but only if they bloom on new growth. Pruning spring blooming shrubs in the winter will remove next year’s blooms. Prune these after they have finished blooming in the spring.

#4 Water

It is vital that perennials, trees and shrubs are adequately watered throughout the fall. Newly installed plants don’t have a fully established root system and would benefit from periodic watering. If the top 1-2 inches of soil is dry, the plants need water. Evergreen trees continue to need moisture in winter, so irrigate thoroughly before the ground freezes.

Arizona Cypress

#5 Take inventory and Think Spring

In the fall, I analyze the landscape. This is the best time to determine what your needs will be next spring. What plants did well in the landscape? What plants need help or need to be moved next spring? Are there any plants that would benefit from dividing such as grasses? What areas need to be filled next spring? Does the canopy of the trees need to be thinned to allow more light into the landscape? Install spring blooming bulbs before the ground freezes.

This is a great season of the year. Take some time to appreciate the beauty of fall. There is so much to enjoy, but set aside some time to prepare for the winter. A little work now on your landscape will pay big dividends in the spring.
