These nutrients include macronutrients like nitrogen, phosphorus, and potassium, as well as micronutrients such as iron and magnesium. Plant food can come in various forms, including organic options like compost and synthetic fertilizers. Using plant food correctly can enhance soil quality and promote healthy plant development. It is important to follow recommended guidelines for application to avoid over-fertilization, which can harm plants and the environment.
