Carefully follow label instructions for use and disposal of fertilizers and pesticides and use less toxic alternatives whenever possible.

Plants and Biological Controls

Select disease and pest resistant plants and learn about biological controls. Call your local County Extension Service Office for free information.

Avoid Over Fertilization

Go easy on fertilizers and pesticides. Test your soil to help determine fertilizer and compost needs for your lawn and garden to avoid over fertilization.

Water Wisely

Avoid over-watering, especially after fertilizers and pesticides have been applied. Water during the cooler parts of the day (late evening and early morning) to reduce water lost to evaporation. Water slowly and evenly with 1 to 1½ inches of water per week so that moisture soaks down to the roots. If it doesn’t grow, don’t water it! Use a broom (not a hose) to clean driveways, sidewalks, and other hard surfaces. Check for leaks in pipes, hoses, faucets, and couplings.
