Spring Lawncare

Spring Lawncare, blog post

April is finally here, which means spring should be bringing in warmer weather. April is a good time to get out and start working in the lawn and garden to prepare our yards. To help ensure that you have the best lawn on the block, here are few tips to improve your lawn this spring.

April is a great time to overseed your lawn. If you had some spots that were flooded out last spring, now is a great time to get some new seed planted. The beginning part of April is best for seeding lawns, but it can be done until the end of the month. Frequent, light irrigation is necessary to keep newly seeded lawns moist. It may be necessary to water twice a day to keep it from drying out and dying. Straw mulch can be applied to keep the seedbed moist, but it is not necessary and can bring problems with weed seed that is often a contaminant of straw. Do not apply any pesticides to newly seeded lawn until you have completed 2-3 mowings. Also, do not try to overseed right before or right after applying crabgrass preventer as this chemical will prevent the germination of your desired grasses as well.

We often face difficulties with weeds in our lawns. The key to weed management is to keep your lawn healthy to avoid weed infestations and to identify the weed before chemical controls are used. Many of our herbicides are specific to either a grass weed or a broadleaf weed and won’t work on the other weed type. Also, you need to know the weed to know the lifecycle for when the best time is to manage that weed with a chemical. As I stated in my previous news column, henbit is a winter annual and should only be chemically controlled in the lawn in the fall, the spring is too late.

Crabgrass pre-emergent herbicides need to be applied before crabgrass germinates, which is when the soil temperature is 55-60 degrees Fahrenheit. This typically occurs toward the end of April. Applying this chemical too soon may cause the chemical to stop working earlier in the season when crabgrass may still be germinating. In this case an additional application may be necessary later in the spring, so it is best to wait until the correct time to only have to apply this one time per season. Broadleaf weeds, such as dandelions, clover, and ground ivy should be controlled in the fall for best control but can be managed in the spring with 2,4-D products.

Fertilizing turf can be done up to 4 times per growing season. Apply fertilizers at a rate of 1 pound of nitrogen per 1,000 square feet for each application. A good trick for remembering when to apply fertilizers is to fertilize with the holidays: Arbor Day, Memorial Day, Labor Day, and Halloween.

We are now getting to the time of year when we will have to start mowing our lawns. Prepare your lawn mower for the season before you start mowing. Start by sharpening the blades. Dull mowing blades can cause tearing to occur on the grass blades rather than a smooth cut. These tears can lead to more insect and disease problems. Change the oil in your lawn mower, if you didn’t do that in the fall. Check your spark plugs and tire pressure. Finally, make sure you clean under the deck for any grass that may still be stuck under there from last season. You can start mowing as soon as the grass starts growing. Remember to mow at a height of 2.5-3.5 inches and only cut off 1/3 of the grass blade each time you mow.
