It is a good time to aerate your lawn. After aerating, fertilize and oversee with milorganite. It will take about 3-4 weeks for the lawn to grow again.

What should I do after dethatching?
After dethatching, rake up the newly exposed thatch. It’s a good idea to mow your lawn to help clean it up. Fertilizing at this time is important. This will allow your lawn to recover and get the needed vitamins and minerals back into the soil.
Should you water lawn after dethatching?
Recovery after dethatching thatch removal can be traumatic for grass plants, so recovery techniques must encourage root repair and deep growth. After ditching, grasses may become more susceptible to drought stress. This is especially true of drought-sensitive species such as ryegrass, clover, and alfalfa, which are more likely to be affected by droughts than other grass species.
In general, ditches should be left in place for a minimum of three years to allow the soil to fully recover from the drought. Ditches that have been in use for more than five years may be removed and replaced with a new ditch if necessary.
Do I need to remove dead grass before seeding?
Allowing the dead grass to build up also weakens the grass around it and will cause more of it to die. It’s important that it’s removed. If you don’t have a lawn mower, you can use a garden hoe to remove grass clippings from the lawn. You can also use an electric lawnmower to do the same thing.
When should I dethatch and overseed my lawn?
The best time to dethatch your lawn is when it’s growing and the soil is moist. After the second mowing, dethatch in late spring through early summer for warm-season grasses. If you don’t have a lawn mower, you can mow the lawn by hand. You can also use a hand-held weed whacker, but be careful not to over-mow. If you do, the grass will die and you’ll have to start all over again.
Can you dethatch too much?
If your thatch is more than 2 inches thick, you may want to consider hiring a professional for the job. Excess thatch can take more than one removal session and can damage your roof.
How soon after dethatching can you fertilize?
Because you fertilize your yard immediately after dethatching, it’s best to wait until your yard has greened up. You encourage weeds to compete with your lawn if you fertilize while it’s still dormant.
If you have a lawn that has been dormant for a long period of time, such as in the spring or summer, then you may want to consider using a nitrogen-based fertilizer.
Nitrogen fertilizers are designed to be applied to the surface of the soil, rather than the roots, so they are less likely to harm your plants.
How long after dethatching can I fertilize?
The dead grass and soil can be collected into piles of debris by shoveling or bagging with the help of a dethatcher. Some you should wait two weeks before fertilization, but the spreader settings need to be adjusted after each use. Insecticides are used to control grasshoppers and other insects that may be present in the soil. The most common insecticides used are pyrethrins and organophosphates, both of which are toxic to humans and animals.
Pyrethroids are the most widely used insecticide in North America, but they are not approved by the U.S. Food and Drug Administration (FDA) for use on lawns. However, they can be used on trees, shrubs, and grasses. In addition to being toxic, these chemicals are known to cause birth defects and reproductive problems in animals and humans.
