Putting Your Garden to Bed for Winter

It seems that winter has come earlier than expected this year.  I don’t know about you, but I have been caught a little off guard.  I wish I could say we have everything ready for winter, but that would be untrue.  In preparation for colder weather, I have put a simple checklist together for putting the winter garden to bed.

Perennials

Every year we receive quite a few questions about when to cut back perennials.  As a general rule, I leave perennials such as wildflowers and grasses stand through the winter. The forms and textures of plants such as little bluestem and switchgrass provide movement in the winter garden and should be left standing. Coneflowers, black-eyed Susans and coreopsis are important seed sources for birds. The dark seed heads and stems look great with a backdrop of little bluestem.

I take note of plants that need to be divided and/or moved next February or March. Diseased plants with powdery mildew or rust should be removed. Those infected leaves will harm next year’s plants.

Lawns

Fall is an important time for lawn care. Obviously, the leaves that fall must be removed or composted into the lawn. More frequent mowing/composting can take care of a majority of the leaves, but if you have large trees, the leaves must be removed. A large covering of leaves will smother your lawn. It is also an ideal time to fertilize cool season grasses. The nutrients will be taken up and stored in the roots for vigorous growth next year. If you have a warm season lawn such as buffalograss, now is the perfect time to control winter annuals such as henbit, dandelions and bindweed. Spraying with a broadleaf weed killer such as 2,4-D will clean up your lawn for next season. Be sure you’re using a spray that is labeled for buffalograss.

Leaves

I purposefully don’t remove some leaves in perennial beds to insulate the plants. In a shade garden, they are perfect as mulch. Just don’t let them get so thick that they smother out your woodland plants. Leaves make great compost that can be used in your garden or flower beds.

Clean and sharpen tools

I often overlook this step in the fall garden prep checklist.  A little time cleaning your tools like shovels, spades and other digging tools will give you a jump start next season.  This simple practice will prolong the life of your tools.  Doing this will prevent rust and deterioration.  I like to use a wire brush in the cleaning process before I sharpen each tool.  By cleaning off dirt and debris and applying a thin coat of oil, you will extend the life of each tool.

Store power tools

We always have trouble with our gas powered tools in spring.  We forget that they need to be drained of standard pump gasoline before being stored for long periods of time.  Today’s gas deteriorates relatively quickly and gums up the carburetors.  Empty your fuel tanks into storage containers of fuel, oil, and fuel mix if you are not going to be using the equipment in the next 30 days.  We add fuel stabilizer to the stored fuel over winter.  We like to run the engine completely out of fuel before we put it away. 

Disconnect and drain garden hoses

Obviously, garden hoses that remain attached to the spigot during cold weather will create problems. This connection and the trapped water in the hose will freeze not only the hose, but the spigot on your home.  I have seen these freeze and then burst as they thaw out.  It can be a mess and quite costly. 

Drain garden hoses before you store them for the winter.  It is best to bring them inside so they are not deteriorated by the winter sun.  Extreme winter conditions also break down the inner lining of the hose, weakening it over time.  We like to loop each hose into two to three foot loops. Create flat stacks of coiled hoses.  Hanging hoses will put stress on the areas where they are attached to the wall.

Spring seems like it is so far away, but it will be here before we know it. By doing a few simple tasks in your garden this fall, you will save yourself time and effort next season. Why not put your garden properly to bed this fall so you can enjoy it more next year? It will be worth your time.

Spring is only six months away!

Rethinking Garden Clean Up

It may not feel like fall yet, but it is coming.  I am ready for some cooler north winds to blow and the leaves to begin changing on the trees. In the back of my mind, I am grudgingly starting to think about garden clean up.

Things are winding down in the garden, except for the asters.  ‘Raydon’s Favorite’ aster, New England asters and ‘October Skies’ aster are a bright spot in the October prairie garden. Pollinators are covering these nectar rich flowers during the warm afternoons. It is fun to watch so many happy pollinators in the garden.  The grasses are spectacular this year too.

Soon these flowers will fade and the growing season will officially come to an end. The grasses that are so beautiful now will blend into the landscape.  It will be time for the prairie to sleep.  Before we settle in for the winter, there are a few things to take care of in the garden so that it’s ready for next spring.

Taking stock

I know we don’t want to think too much about the landscape, but if you don’t take a few notes now, you will forget by spring.  I know that will happen to me, so I like to spend a few moments reflecting on what has worked and what didn’t in the gardens. 

Do I need to add a few plants to fill or augment my current design? Should I move some plants to make them happier? I take note of plants that need to be divided and/or moved next February or March.  What areas am I going to focus on next year?  Do some of my trees and shrubs need pruning?  What plants have I seen that I believe would work well in the landscape?  What do I need to do to create habitat for wildlife? 

Fall is also a great time to appreciate what you have accomplished.  Even a few steps toward a more sustainable landscape should be recognized.  Your project may not be complete, but you can see progress.  Give yourself a pat on the back.  Your stewardship efforts are making a difference.  Hopefully, you know this and have seen evidence of it in your garden. 

Perennials

We have been rethinking how, when and why we do cleanup of our perennial beds.  It is generally better to leave perennials such as wildflowers and grasses as they are through the winter. The forms and textures of plants such as little bluestem and switchgrass provide movement in the garden and should be left standing. The dark seed heads and stems look great with a back drop of little bluestem.  Enjoy these autumnal combinations. 

Little Bluestem

Wait! Don’t clean up your garden too early.  Cleaning up beds often removes natural food and shelter that wildlife need to survive the winter months.   Coneflowers, black-eyed susans and coreopsis are important seed sources for birds.  Many pollinators and other insects overwinter in stems and tufts of grass in the landscape.  By prematurely removing all dead vegetation you are removing overwintering wildlife.  We have found that it is better to cut these plants down in February and March, but leave the stems in the garden as mulch.  Overwintering pollinators and insects hatch in the spring and these composted plants are a fantastic mulch that add nutrients back to the soil.  In our experience, overzealous cleaning often does more harm than good. 

Leaves

I love the fall color of the trees in October. However, once the leaves have fallen, what should be done with them? I purposely don’t remove some leaves in perennial beds so they can insulate the plants. Keep in mind that too many leaves or larger leaves tend to cake up and seal off the soil. This will keep the soil too wet through the winter for many perennials.

When you are dealing with large quantities of leaves you may need to remove them or shred them so they break down quickly. In a shade garden, they are perfect as mulch. Just don’t let them get too thick that they smother out your woodland plants, too. Remove leaves from your turf areas, but don’t haul them away.  They make great compost that can be used in your garden or flower beds.

Trees

This is the worst time of the year to prune trees. Trees are going dormant and pruning now will encourage new growth that will not get hardened off before cold weather. It is better to take note of trees that need pruning and remove suckers or limbs when the trees are completely dormant in November through January. Pruning now will only weaken the tree and reduce its winter hardiness.

Spring seems like it is so far away, but it will be here before we know it. By doing a few simple tasks in your garden this fall, you will save yourself time and effort next season. Why not put your garden properly to bed this fall so you can enjoy it more next year? It will be worth your time.

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!
