Fall is just around the corner and the lawns in the area are waking up from their heat and drought induced dormancy.
If you have kept up with at least biweekly mowing you probably have a good handle on weed control, but if you let the lawn go you are likely to have more weeds in your yard than before the drought started. Getting your lawn back to a healthy condition will help get those weeds back under control.
I see a lot of people mowing their lawns short which is stressful on the lawn. Cutting the lawn at 3 inches will keep the lawn healthier as it makes it easier for the lawn to retain moisture and shades the soil from the sun. Other things that can be done to help the lawn recover include:
Aeration - This is a process that pokes small holes in the lawn making it easier for water and air to reach the root system of your lawn. It also helps with compacted soil so the roots can grow better. Aeration will help break up thatch that can develop in lawns.
Over Seeding - Often done after aeration this is simply adding grass seed on top of the existing grass. The seeds will drop to the soil level and into the aeration made holes where they can germinate and thicken the lawn.
Top Dressing - Some people will choose to Top Dress their lawn. While the other steps are relatively inexpensive, top dressing is labor intensive and requires a lot of soil be added so can be costly to have done so not everyone chooses this process. It involves calculating the amount of soil needed to cover the lawn with 1/4 inch of soil. Top soil weighs around 2000 pounds per cubic yard depending on moisture level so it usually is delivered to the job site then shoveled into a wheelbarrow to be put in small piles in the work area. Then you use a rake to spread the topsoil over the lawn. The topsoil will settle into low spots and between the grass blades to add to the depth of your soil. You don't want to completely cover the grass so have to spread it out well.
Ideally you would do all 4 steps, mowing - aeration - over seeding - and if desired top dressing one right after the other as you won't want to mow right after over seeding or top dressing. With luck it will rain a couple of days after top dressing to help settle the new top soil. If not, it is a good idea to water the lawn a couple of times to settle the top soil before mowing again.
