How can I prevent the return of spider mites, which were a big problem in my beans and melons last summer?
These spiders are most problematic when the weather is hot and dry. Keeping your plants well mulched and misted will help deter them, as they hate cool, moist conditions. You can destroy the webs of these spiders with water bursts from your hose. Spraying with an insecticide is another solution. Do this three times at one-week intervals to kill the mites plus any developing eggs.
