Short answer: yes. Although aeration is beneficial for most lawns and soil types, if it’s done too frequently, you can weaken the grass’s roots so much that they’ll begin to have trouble. Generally, most lawns can be aerated as infrequently as once every one to three years, although those with more foot traffic and compaction may benefit from aeration up to twice yearly.

There are plenty of products to help green up your grass. Try an iron supplement spray or fertilizer that is rich in nitrogen. You can also apply a thin layer of compost on top of your lawn at the beginning of spring to give the grass a nutrition boost, which helps it achieve that bright color you are looking for. 

The screwdriver test involves trying to push a screwdriver into your lawn. If it goes in easily, you’re likely overwatering and should cut back. If there’s moderate resistance, you have a good watering schedule and soil composition. If there’s a lot of resistance or you can’t get the screwdriver into the soil, you may need to aerate your lawn to reduce compaction and increase your watering schedule.

Yes, you can overwater your grass. Depending on your climate, it could be easier than you think. While water is an essential element for lawn growth, too much of it can actually damage its roots, leading to rot and other damage.

Whether your drip irrigation system leaks, it’s been a rainy summer, or you use the sprinkler too often, overwatering your lawn can drive up your water bill and impact the longevity of your lawn.
