Use organic compost or organic fertilizer. Do this only in spring or early fall, otherwise you’ll be feeding your annual weeds.
Say no to Pesticides
Caring for your lawn without synthetic chemicals is easy and doesn’t have to be costly. You’ll be pleased with the results, especially if you aren’t in a big hurry to achieve that “golf course” look, or if you enjoy the pleasant naturalized color and texture variation that comes with a healthy mixture of plants.
Read the Labels!
Before you purchase a lawn product, read the whole label. The label contains ingredient lists, safety and handling information, and instructions for use and disposal. If the product says it is a hazard to humans or the environment, it is best to avoid it.
Lawn Tip – Dont Mow to Low!
This is easiest way to ensure the health of your lawn through the summer. When in doubt, just raise the mower all the way to its tallest setting. You never want to cut more than about one-third of your grass in any single session. Yes, this does mean you’ll need to mow with a little more regularity, but don’t fret: the growth of your lawn will slow considerably as the temperature average goes up. By maintaining a tall lawn, you deter weed growth and allow the grass to root deeper into the soil.
Equipment Tip – Maintenance
Chances are your mower has been sitting dormant in a garage for three, four, maybe even five months. It’s time to get that thing out and show it 
some love. There are a few things you’ll need to do. First, change the oil, air filter and spark plug. This is basic yearly maintainence that will keep your machine running smoothly for years longer than it would if you neglected it. If you don’t care to attempt these upgrades yourself, a mower repair shop or sales facility will take care of it for you in exchange for a bit of money.
