Some gardeners use a homemade insecticide for plants, such as salt spray, mineral oil, or garlic spray. Use these natural insecticides and organic pesticides to fight off pests without causing harm to you or the plant. Just remember to reapply these natural garden pesticides frequently, especially in rainy climates, and check to see if your organic pest spray is actually organic.
The easiest way to prevent insect damage in your garden is to discourage them from coming in the first place. A healthy garden is the best defense.
They may already be infected. If not, they will attract predators. Pull the plant and dispose of it away from the garden area..
Natural composting methods, mulching, and top-dressing your soil with compost or natural fertilizer is the best way to develop strong, vigorous plants.
Practising no-dig or no-till gardening will help minimize the introduction of pests to the soil and increase the beneficial microbes.<
Insect pests are often plant specific. When plantings are mixed, pests are less likely to spread throughout a crop. Rotating crops each year is a common method to avoid re-infestation of pests that have over-wintered in the bed.
Water early so foliage will be dry for most of the day. Wet foliage encourages insect and fungal damage to your plants. See our page on drip-irrigation for methods of delivering water to the root systems without wetting the foliage.
