Many plants are naturally resistant to pests or have been bred to be so. Talk to knowledgeable nursery personnel or do your own research in gardening books. Diversify your Garden. Variety in your garden will help prevent a situation where a pest can rapidly devastate a large group of identical plants. Maintaining nectar and pollen-rich plants in your garden attracts the adult stages of many beneficial insects that feed on pests.
Flowers attract honeybees to pollinate fruit and butterflies to add beauty.
Use Mulch to Prevent Weeds. Many weedy plants are specifically adapted to grow best in bare or disturbed soil. Covering the soil with mulch eliminates their habitat. Take Care of your Soil. A healthy soil, one which harbors abundant populations of earthworms, fungi, and bacteria, keeps your plants vigorous and resistant to attack by pests and diseases.
