No worries. Miracle Grow is a fertilizer and fertilizers are perfectly safe to use on edible plants. You must be thinking about pesticides that kill pests that you should be careful about using on edible plants. Vegetables need fertilizer and organic farmers use plant food from an organic source but most farmers and home gardeners are more successful using plant food or fertilizer that is more easily available to the plant and more complete from a packaged fertilizer either one you add to water or soil such as Miracle Grow or a slow release plant food such as Osmocote in pellets or in granular form. Enjoy your home grown, healthy produce this summer and remember to fertilize with no worries. Keep growing, Marianne Binetti
