How can I have a healthy, pest-free garden without chemical pesticides and fertilizers? |
Many commercial garden products contain toxic chemicals that can affect the environment and your health, but there are alternatives. With a well-conceived landscaping plan, you can reduce the need for pesticides and fertilizers and make your garden selfmaintaining. Start with plants native to your area and appropriate for your climate (they require less maintenance), and plants that attract beneficial insects (which keep some pests away naturally). Organic compost keeps soil healthy, while mulch discourages disease and pests. Using materials found on your property (e.g., pine needles, dry grass clippings, twigs, shredded leaves) benefits your garden while reducing waste.
You can also make effective, nontoxic pest control formulas using some common household items. Liquid soap, for example, serves as an all-purpose pesticide. Dilute a few tablespoons in a quart of water and mix with strong-smelling substances such as garlic, cayenne, horseradish, or onion, then spray on plants weekly. Physical barriers can also keep pests at bay: A layer of crushed eggshells around stems presents sharp edges that deter root maggots and slugs, while providing calcium for the soil. Coffee grounds and tea leaves are other good pest repellents.
