Restoring a lawn after it has gone dormant in the summertime requires a slightly different approach than restoring a lawn after wintertime. When a lawn goes dormant in the summer, it means that the grass has stopped growing and has turned brown or yellow due to lack of water and heat stress. Restoring your lawn after summer dormancy involves rehydrating the soil, providing nutrients, and encouraging new growth.
The first step in restoring your lawn after summer dormancy is to water it deeply and thoroughly. This will rehydrate the soil and encourage the grass roots to start growing again. It's essential to water your lawn deeply, as shallow watering can lead to shallow root growth, which makes your lawn more susceptible to drought stress. You should aim to water your lawn at least once a week, providing it with one inch of water.
Next, you'll need to fertilize your lawn with a high-nitrogen fertilizer. Nitrogen is essential for promoting new growth, and a high-nitrogen fertilizer will provide your lawn with the nutrients it needs to recover from summer dormancy. Make sure to follow the manufacturer's instructions when applying fertilizer to your lawn, as over-fertilizing can damage your grass.
After fertilizing your lawn, you'll need to mow it regularly. This will help to encourage new growth and keep your lawn looking neat and tidy. When mowing your lawn, be sure to cut no more than one-third of the grass blade length at a time. Cutting more than this can cause stress on the grass and make it more susceptible to disease and pests.
Finally, it's important to keep an eye out for weeds and pests, as they can quickly take over a weakened lawn. You can control weeds by applying an herbicide, and you can control pests by using an insecticide. However, it's important to use these products sparingly and only when necessary, as they can also harm beneficial insects and pollinators.
In summary, restoring a lawn after it has gone dormant in the summertime requires rehydration, fertilization, regular mowing, and pest and weed control. By following these steps, you can encourage new growth and restore your lawn to its healthy, lush state.
