The key to minimizing the potential for pollution is to use them responsibly — at the right time, in the right amount, in the right place and for the right reason.

Before applying fertilizer, test your soil and apply only the amount recommended.

Consider slow-release or organic fertilizers.
Improve soil fertility through adjusting soil pH or acidity. For many plants, especially lawns, this involves applying lime to raise the pH. Soil fertility is also improved by increasing soil organic matter through the use of compost and mulching.

Before applying a pesticide, be sure that you have correctly identified the pest or pests.

Avoid using pesticides as a routine, preventative measure.
If a pest problem has been correctly identified, determine if uniform treatment is needed or if spot treatment can work.
Determine if there are alternative control options such as mechanical, biological, or cultural methods.

View our Healthy Lawn Care page for more information on pest management and proper application methods.

Alternative White Grub Control

Apply the amount of fertilizer and/or pesticide intended by measuring the treatment area and calibrating your spreader.

Avoid applying fertilizers and pesticides on paved surfaces and near storm drains, surface waters and drinking water wells. Drop spreaders allow for controlled applications.

Always read label directions carefully and store these products in dry, well-ventilated places in their original containers.

Buy only the amount needed and dispose of unused products properly. Give leftovers to a neighbor or contact the RI Eco-Depot for proper disposal options.
