Plants with similar water or sunlight requirements should be planted in the same area. For example, don't place drought-tolerant plants in or next to a lawn. Native flowers, shrubs, and trees are often good choices because they are well adapted to local conditions and require minimal care. Plant natives based on their natural growing habits. Select seeds and seedlings known to resist pests and disease and suited to the climate and soil where you live.
Many pests prefer specific kinds of plants.
Don't provide them a continued source of food. For example, rotate potatoes, tomatoes, and peppers with other kinds of plants. Mix vegetables and herbs by planting in alternating rows or small blocks. Talk to your nursery about crop rotation. Some pests don't show up until late in the growing season, so plant susceptible crops early.
