Yes, Osmocote is safe for all edible plants and is also good for the environment as there is no excess fertilizer running into water supplies and causing algae bloom and other issues. Even if the Osmocote label has pictures of flowers, you can safely use it on your vegetables. Tomatoes love sunshine and heat and the Osmocote releases nutrients right when your tomatoes need them the most during active growth. Enjoy a great harvest, Keep growing, Marianne Binetti
