3. What about lawncare and fertilizing?
Lawn Care And Fertilizing
Fertilize lawn grasses at eight to ten week intervals during the growing season. The first application should be made six to eight weeks before the first expected killing frost. Apply a 3-1-2 or 4-1-2 ratio fertilizer at each of these times. Rates of application will be listed on the package.
Obviously, excessive rainfall and other climatic factors can result in more frequent feedings for newly installed lawns. Start your fertilizing 6 weeks after installation. Use no weed killers for 10 to 15 weeks.
Most young grass is very sensitive and it is safer simply to wait, instead of taking the chance on chemical damage. Mowing will eliminate most of the weeds. Mow at recommended heights, don't let your grass get long and lanky.
There are several non chemical alternatives for use against insects or fungus, or organic fertilizers. An excellent resource is the Internet.
