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.

Dos and Don’ts of Autumn Yard Work

Gardening in the fall is different from gardening during the summertime.  In my opinion, autumn yard work could barely be called work and borders on fun.  The weather is perfect.  Cool days with warm sunshine lure us outdoors.  Take advantage of this wonderful season, because winter will be here before we know it.  There is so much that can be done in our landscape, but how do we prioritize those chores?  Here is a list of dos and don’ts to help focus your efforts this autumn season:

Dos:

1. Plant anything and everything.

Trees, shrubs, and perennials benefit from warm soils and beneficial autumn rainfall.  Plants properly established will have a head start next spring. Perennials should be planted well before the end of October. Install spring blooming bulbs, tree and shrubs before the ground freezes.

2. Take inventory and think spring

Analyze each area in your yard to determine how plants performed through the year and what will enhance the landscape.  A quick check now will guide your efforts next spring.

3. Clean up leaves

Remove leaves from display beds so that plants don’t get smothered.  Collected leaves can be composted, which makes excellent plant food and humus.  Analysis shows that, when composted, leaves from most trees can contain up to twice as many minerals as aged manure.

4. 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.

5. 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 if needed before the ground freezes.

Don’ts:

1. Do not remove seed heads and stalks.

In certain gardens, we deadhead spent blooms on plants such as gray-headed coneflower 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. Seedheads to leave through the winter include black-eyed Susans, sunflowers, coneflowers, grasses, and trees and shrubs with berries.

2. Do not remove habitat.

Logs, leaf piles, brush piles and perennials such as grasses are havens for insects that overwinter in the garden.   These beneficial insects will be drawn to your yard if you provide even just a few of these elements in the landscape.

3. Do not prune trees and shrubs.

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. Don’t let leaves smother your lawn.

Too many leaves will shade lawns and choke out grass.  Either rake and collect them or shred them if they are not too thick.

5. Do not leave out weather-vulnerable pots.

Clay pots are an investment that can be lost with the first freeze.  If the soil inside the pot freezes, it will expand, causing it to crack.  It is best to remove the soil and put the pot in the garage or tip upside down.  There may be ways to” winter proof” these pots with soil in them, but I don’t like to take the chance.

6. Don’t let weeds go to seed.

This seems obvious, but those weeds have a way of hiding.  Look thoroughly at your landscape.   A little work now with weed removal will pay dividends next year.

 

Don’t stay indoors this fall.  Do have fun being outdoors in your landscape!
