No matter your weather, spring is peak time for yard cleanup! From pruning trees to crabgrass prevention, here are 10 tips to cover all you need to know now. There鈥檚 a right way to care for your yard, lawn, and garden beds in the spring months.
Lawn and yard care is all about being proactive. We put a lot into our home and property, so it鈥檚 time to refresh our memory on what鈥檚 next.
1. Prune in Late Winter and Early Spring
If you haven鈥檛 already done so, cut off any broken or badly disfigured branches caused by winter storms.
Unwanted lower branches on all evergreen shrubs and trees should also be removed in late winter.
Most shrubs and trees are best pruned in late winter or early spring, but not all. Got flowering shrubs? When to prune a shrub depends mostly on when it blooms and whether it flowers on growth produced in the same or previous years.
- Prune summer-flowering shrubs hard at the end of winter or very early spring BEFORE any new growth starts! They form their flower buds on 鈥渘ew鈥 wood (i.e., wood that will grow this spring). Examples include butterfly bush, smooth hydrangeas, panicle hydrangeas, and roses.
- Prune spring-flowering shrubs after spring flowers fade. Since they bloom on the growth of the previous season (鈥渙ld鈥 wood), you will be cutting off their buds and flowers if you prune too early. Examples are: azalea, forsythia, mophead hydrangeas, lilacs, and wisteria.
See our complete pruning guide to common shrubs, bushes, and trees.
2. Clean Up Leaves鈥擥o Easy
Even if you cleaned up some leaves in the fall, there are many trees (such as oaks) that shed leaves (and broken or fallen branches) over the winter and well into spring. Now, let鈥檚 not go crazy as if we have to clean up every single leaf off our lawn to compete in the neighborhood beauty pageant. A little leaf litter helps our pollinators and wildlife survive the winter.
Remove any debris or heavy piles of leaves or any layers of leaves. This invites mold, disease, and decay. However, don鈥檛 rake into wet ground. It鈥檚 best to wait until temperatures are reaching the high 40s or the 50s. If you have a compost pile (or want to start one!), add those leaves to the pile. Otherwise, just mow any thin layers of leaves in with the season鈥檚 first cut, and they鈥檒l also break down and add organic matter and nutrition to the soil.
If you have perennial beds, wait to cut down those spent perennial stems until the weather has definitely warmed and it feels like spring is here to stay. So many beneficial insects (ladybugs, native bees) and predators (lacewings, parasitic wasps) are still 鈥渉ibernating鈥 in leaf litter or hollow plant stems. They will 鈥渨ake鈥 up as the weather warms and daylight increases. If you just can鈥檛 stand to wait, cut those spent plant stems and simply set them at the edge of your property or the woods. The native bees will thank you!
3. Address Aggressive Weeds鈥擡arly!
Deal with weeds in early spring. Invasive or aggressive weeds will only get worse as daylight hours increase during summer. As they grow, their roots will strengthen, and they will be very difficult to pull out.
The best way to minimize weeds in your lawn is through good cultural practices:
- Do not mow too short
- Allow mow clippings to return to the lawn
- Skip spring fertilization
- Do not over- or underwater
- Devote some of your lawn to wildflowers
You may also choose to apply an organic or traditional 鈥減re-emergent鈥 herbicide. The best time to apply a pre-emergent is when the temperature in the top 1 inch of soil has been 55 degrees F for five consecutive days (often in March and April). Once the soil temperatures reaches 55 degrees, annual weed seeds begin to germinate. Once you can see weeds in your lawn, a pre-emergent herbicide is not effective.
If you see weeds emerge in the spring, spray a post-emergent herbicide (traditional or organic). Wait to apply broadleaf weed killer until late spring, after the weeds have flowered. (Often, this is 6 to 8 weeks after a pre-emergent herbicide.) Weed killers are most effective when applied evenly over the entire lawn.
See common lawn weeds to identify what鈥檚 most common in your yard!
A word on dandelions: A common perennial weed in early spring, dandelions can also be dug out by their roots鈥攐r, just enjoy their yellow blooms. If you maintain a yard without chemicals, you could always harvest dandelion greens when young and tender! Note: Snap off dandelion heads before they seed if you don鈥檛 want more dandelions next year.
4. Seeding Bare Patches鈥擟arefully
Winter can reveal damage to your yard from pets, snow plows, and traffic. You may wish to re-seed some spots.
The conundrum is that if you鈥檙e using a pre-emergent herbicide in the spring for crabgrass, it鈥檚 nonselective and will deter grass seeds from growing, too; this is why fall is a better time to seed grass. However, if you just can鈥檛 stand those bare spots, try spot-seeding bare patches as early as possible (by April) before you apply any pre-emergent for crabgrass control.
Give seeds enough time to germinate and somewhat establish. If this is not possible, don鈥檛 skip the pre-emergent weed control. It is better to take care of the bulk of your yard; wait until fall to perform any turf repairs.
Before seeding, use a steel rake to scuff up the area. Loosen the soil. Scrape some compost into the area. Sprinkle grass seed on the spot. (Use a sun/shade premium mix, unless the area鈥檚 heavily shaded.) Keep the soil moist. Cover the seeds with straw matting or another material. Even grass clippings will do. You just want to cover the spot with some sort of material to hold seeds in place.
If you鈥檙e then applying pre-emergent herbicides, we would also fertilize any spots in the lawn early; in a few weeks shoots will grow and fill in the brown spots. If the brown patches are too big or you just can鈥檛 wait, sod is the better option.
5. Rake Away Thatch鈥擭ot 鈥楾il Dry
It鈥檚 too early to talk about thatch, but we need to do it now because many folks do it way too early. When we say 鈥渢hatch,鈥 we鈥檙e talking about the matted areas that have died out; they can harbor snow mold. You don鈥檛 want more than 1/2-inch of thatch on the ground. A good raking will promote airflow throughout the grass, prevent disease, and help germination. It鈥檚 essential the ground and grass are dry enough, or you will do more harm than good raking up grass seeds.
Rule of thumb: If footprints remain after walking, the grass is still too moist to de-thatch. That said, rake as soon as it鈥檚 dry and the grass is still brown; raking too late will harm healthy roots.
6. Do Not Fertilize Too Early
The best time for fertilizing is autumn; this helps build turf by giving grass plants the food they need to build up their root systems.
However, many people also fertilize in the spring. Do not fertilize too early in the spring. This will divert the plant鈥檚 energy into leaf development too soon. Instead, the grass needs phosphorus for root development.
The best time for the first spring application in most regions is late spring (around May), just as the grass is beginning to grow green and you want to promote a lush, green lawn. Fertilize before the heat of summer begins and after the grass is growing nicely. A good feeding of 3/4 to 1 pound of fertilizer will allow the plant to rebuild its food supply.
When you fertilize grass in the spring, apply lightly. Heavy nitrogen (N) fertilization is not good for the grass and can also lead to disease problems. A healthy lawn is a light, bright green color; if it鈥檚 darker, that means too much nitrogen (which will also run off into our water supply). Remember that you can always start lightly and add more until you get the right color.
Also, consider a mulching mower鈥攚hich returns grass clippings back to the soil. This saves you time and energy, while also improving the condition of your lawn. Since grass clippings contain up to 90 percent water, the clippings dry up very quickly. It鈥檚 almost as if the grass clippings disappear. Plus, this returns 25 percent of the nutrients to the soil鈥攁 fantastic fertilizer.
7. Loosen the Soil鈥擨f It鈥檚 Compacted
Do you have flower beds? After the winter, the soil in your garden beds may be completely compacted. Remove thick layers of leaves that cover evergreen ground cover beds. Thin layers of leaves in your beds can be left alone and simply mulched over later. They鈥檒l break down and add organic matter to your soil. Then, loosen the soil to help oxygen reach the plants鈥 roots. You can use hand tools for small areas, but larger areas may benefit from tilling.
A grass lawn also gets compacted soil, especially if people walk on it. If you see patches of moss or signs of decline, we would advise aerating the lawn; this allows water and air to reach the root zone faster, resulting in new growth and increased root development. However, this is usually best done in the fall. Plan to rent a lawn aerator at your local home improvement store. If you aerate in the spring, it is important to core aerate before the soil temperature reaches about 55 degrees F. As it warms, you鈥檙e simply making room for and inviting, aggressive weed seeds to find a home.
Moss can also mean that your lawn is getting acidic. If you are growing grass, the goal is a neutral pH. Get a soil test (often free or done for a small fee through your local County Cooperative Extension office). If your lawn is acidic, you鈥檒l need to apply lime to it; the Extension folks can advise you.
8. Redraw Beds鈥擶ith a Garden Hose!
You may wish to redraw the boundary between your garden beds and grass in springtime. Wider beds mean less lawn care, too. Here鈥檚 a simple way to do it yourself: Use a garden hose to mark out a nice line for your garden beds. Then, along this bed line, take a sharp metal edger and drive it into the ground as deep as it will go. Dig all along the hose line and then remove the grass that鈥檚 there, creating a nice bed. Once done, fill up the bed with 2 to 3 inches of mulch (pine bark is a good choice)鈥攐r you鈥檒l just get a bed of weeds! Then, you鈥檙e ready to transplant or plant perennial flowers.
9. Mow Grass鈥擝ut Not Too Soon
Mow the lawn when the grass level reaches 2 to 3 inches tall. The lawn needs time to recover after winter. However, if the grass grows too long, it shades the roots, which allows fewer weed seeds to sprout.
If you use a traditional lawn mower, spring is the time to clean (or replace) the filter and spark plugs. It鈥檚 important to sharpen the mower blade every month or two for a clean cut. When you just rip grass and leave it with open cuts, you leave your yard susceptible to fungi and disease. See more about lawn care.
If you鈥檙e interested in alternative mowers, consider a reel mower or an electric mower as a more environmentally friendly option. These mowers work best if your property is one-third of an acre or less. It鈥檚 important to mow your grass regularly, as it鈥檚 much more difficult to cut the grass if it gets way too tall (as many of us have experienced firsthand!).
Of course, we have to mention that there are alternatives to grass as well! Many folks are using more ground cover plants (such as sedum), walkways, and wider flower beds. There鈥檚 also a growing trend to add vegetable garden beds or to integrate edibles (herbs, vegetables, fruit) into your front yard.
10.&苍产蝉辫;惭耻濒肠丑鈥擟补谤别蹿耻濒濒测
As with leaf removal, don鈥檛 mulch too early. Be patient. There are also many beneficial insects and pollinators (e.g., soldier beetles, native bees, hummingbird clearwing moths) who overwinter in your garden, and smothering your ground with mulch is not helpful. Just hold off on mulching chores until the soil dries out a little and the weather warms.
We mulch once we have edged our beds and trimmed dead branches on our shrubs. Then add your mulch (or, replace your old mulch). We prefer a heavy mulch, such as hardwood bark mulches, over dyed brown wood chips. They are higher quality, last longer, and look better. Read more about the benefits of mulching.
Not everything on this list is necessary for every yard, but we think that we鈥檝e covered most of what you need to know for spring!
