Fertilize only as needed following the recommendations on your soil analysis.
Fertilize only as needed following the recommendations on your soil analysis. Crops with long growing seasons, such as corn and tomatoes, may need additional fertilizer partway through the growing season. Watch for symptoms of nitrogen and other nutrient deficiency (including leaves turning yellow and slow growth). Avoid the urge to overfertilize, which can produce lush plant growth but decrease flowering and fruit development and increase pest problems.
