Wet leaves on crowded plants are subject to diseases. Thin plants to increase air circulation and avoid touching the leaves while they are wet.
Diseases & Pests: Cutworms and root maggots can attack seeds and seedlings. Allowing for good air circulation between plants and taking care not to over fertilize can slow foliar disease, both fungal and bacterial.
Companion Planting: Beans fix nitrogen in the soil. Plant with Brassicas, carrots, celery, chard, corn, cucumber, eggplant, peas, potatoes, radish, and strawberries. Avoid planting near chives, garlic, leeks, and onions. Pole beans and beets stunt each other’s growth.
