While your lawn may not require as much care in the winter as it does in spring, summer, and fall, you don’t want to ignore it completely. To ensure it will be in good shape come springtime, you’ll want to take the following steps.
Aerate & Fertilize
Just before your area’s first expected frost date, aerate your lawn. Aerating your lawn will give it a chance to breathe before the grass goes dormant, and help relieve any compaction that has built up during the warmer months.
After you’ve opened up your lawn, it’s a good time to fertilize. Fertilizing your lawn gives your grass the essential nutrients it needs as it prepares for winter. The grassroots absorb and store the nutrients during the winter months. Then, in the spring, your lawn taps into those stored nutrients giving it a head start, making it green and lush. By having a properly cared-for lawn, you’ll also help prevent weeds, pests, and diseases from moving in once it warms up.
Keep Your Lawn Clean
There’s a good chance that leaves have piled up on your lawn during fall and because of that, your lawn could suffocate before winter. Leaves that are left on the lawn could also become too wet, which can invite disease. If the leaves are not too thick or wet, mulch the leaves with your mower into dime-sized pieces to recycle the nutrients back into your lawn. If the leaves are too thick, wet, or matted down, rake them up and remove them.
Also, be sure to remove lawn furniture and debris from your lawn, as well as any spare logs from next to the fire pit.
Avoid Too Much Lawn Traffic
When your lawn is frosted or dormant, try to avoid walking on it too much. Even strong grass can become weak if the same path is walked over too many times.
Most of us begin the New Year armed with plans, projects, and resolutions. The January lawn & garden provides a stark contrast as it hunkers down to wait out the winter, but there’s still plenty to do when the weather cooperates.
The month of January takes its name from Janus—the Roman god of Gateways and Journeys—who is often pictured looking both backward and forward at the same time. New Year’s resolutions spring from this tradition, and your January gardening can follow suit.
This is a great month for evaluating and planning. It’s also a good time to work on plants during dormancy, so they can begin their spring growing season with an advantage.
Here are some lawn & gardening chores to tackle during January.
Trees and Shrubs
In January, you can continue these chores from December:
- In warmer zones, protect tender trees and shrubs from surprise frosts by covering them with burlap draped over a simple wooden frame or plant stakes.
- Inspect stakes and wires on newly planted trees, to make sure they are still straight and not damaging the bark.
- Stake leggy plants to protect from wind or ice breakage.
- Leave snow in place as an insulator – remove (gently!) only if the weight of the snow threatens to break the plant. Do not attempt to remove ice.
You can also:
- Prune dormant trees and shrubs now, including fruit trees. In warmer zones with winter-flowering shrubs, wait until just after they bloom.
- Hold off on pruning spring-flowering shrubs until after they bloom.
- Inspect your winterized roses – make sure they are still firmly tied and/or covered.
- Apply anti-desiccants to newly planted evergreens.
- Bring spring-flowering branches indoors for forcing. Good choices are forsythia, pussy willow, jasmine, and flowering quince.
Zones 7 and warmer can:
- Begin planting roses.
- Plant bare-root, balled-and-burlapped, and container-grown trees and shrubs. It can be hard to identify plants when dormant, so hopefully, you’ve made some notes during the growing season!
Perennials and Bulbs
Continue these tasks from previous months:
- Protect evergreen perennials from freeze damage. Use boughs from your recycled Christmas greenery as an extra mulch layer.
- Check your stored tender bulbs every couple of weeks. Discard any rotten ones. If they look withered or dried out, mist the packing medium very lightly with water.
- Brighten up cold, gray days by bringing out your chilled bulbs for forcing indoors. Also plant bulbs that don’t require chilling, such as paperwhite narcissus.
- Sow seeds in indoor flats for spring planting.
Also, you can:
- Clip faded blossoms from gift amaryllis.
- Take a tour of your garden to see if any of your plants have been uprooted by frost heaving. If so, add extra mulch.
- Zones 7 and warmer can plant summer and fall flowering bulbs.
- Frost-free zones (11 and warmer) can plant spring annuals outdoors.
Annuals and Containers
- Continue to protect tender container plants from freezing temperatures.
- Keep watering containers.
- Feed winter-blooming pansies with a bloom-boosting fertilizer.
- Start seeds indoors for summer annuals.
- Remember not to walk or drive on frozen grass.
- Apply post-emergence weed control to actively growing broadleaf weeds.
Fruits and Vegetables
- Inspect stored fruits and vegetables (such as apples and potatoes) for decay. Throw away any that look spoiled, and increase air circulation to reduce further damage.
- If your winter vegetables are looking yellow, add some nitrogen fertilizer
- Prune dormant fruit trees and grape vines.
- Continue applying dormant spray to fruit trees. Don’t spray during wind, rain, or freezing temperatures.
- Sow seeds indoors for spring vegetable planting.
Continue these chores from previous months:
- Keep houseplants out of drafts and in the brightest spot possible.
- Increase humidity around tropical plants.
- Reduce fertilization, but continue watering (may water less often, but the same amount). Make sure your water is room temperature.
- Address any insect and disease problems.
- Give extra protection on chilly nights by closing drapes and making sure plants don’t touch the cold glass.
- Cover or wrap new houseplants when transporting to keep them from freezing on the trip home.
Cleanup and Maintenance
Continue these chores from previous months:
- If the ground isn’t frozen, install French drains, bury downspouts and drainage pipes, and watch for drainage problems in the garden.
- Have your soil tested to determine if supplements are needed.
- Till workable soil and work in amendments. This gives you the added benefit of exposing buried insect eggs and larvae to hungry birds.
- Don’t forget to feed the birds!
- Clean, oil, and repair garden tools.
- Take in your lawn mower in for blade sharpening or repairs – the repair shops are much less busy this time of year.
- Keep plants clean by gently wiping or rinsing.
