What food do plants need to grow?

Plants primarily need macronutrients like nitrogen, phosphorus, and potassium, which are essential for their growth and development. They also require secondary nutrients such as calcium, magnesium, and sulfur, along with micronutrients like iron, manganese, and zinc in smaller amounts. Additionally, plants rely on water and sunlight to facilitate photosynthesis, which is crucial for converting these nutrients into energy. Healthy soil rich in organic matter helps provide these essential nutrients for optimal plant growth.
