Develop a tolerance for pests
A few weeds or insects won't harm your healthy lawn. Before using pesticides, try improving your lawn with some occasional hand weeding.
Hand weeding can be beneficial if you have sensitive plants, or a vegetable garden where there can be concerns about spray drift.
Evaluate your lawn care practices
Developing a certain level of tolerance for some weeds in your yard is a no-cost, no-effort alternative to weed control. Often, recurring pest problems are a sign that lawn care practices need to change.
Examine your lawn care program and the condition of your lawn to determine if anything needs to be done differently. Improving the management of lawns gives long-lasting results and avoids future pest problems.
