Fertilization should be done regularly but in moderation. Spring fertilization is great for a quick green up, but late autumn is the optimum time for good grass root growth. Your lawn will go into winter in a healthy state and green up quickly in the spring. Compost, composted manure or other organic products such as corn gluten meal, make nitrogen available immediately but also over a longer period of time as does a slow-release granular fertilizer.� If you're uncertain how much fertilizer to apply, a soil test determines the current fertility level. Sampling instructions are available from your local county extension office.
Longer grass prevents weeds from sprouting and reduces the need to water. Set the mower to 3 inches, mow regularly and keep the blade sharp. Try not to take more than a third of the length of the grass each time. Lawns that are mowed too short have poor heat and drought tolerance and are an invitation to weeds. Clippings left on the lawn as mulch reduce the need for other fertilizers. If the grass was very long, compost the clippings instead of leaving them on the lawn. A mower that can mulch the clippings or bag them is a good choice.
Summer is a time to enjoy our gardens and lawns. The above steps can help reduce dependence on lawn chemicals and give us a little extra time to sit back and enjoy the green grass and warm sunshine.
