The best plant food

Plant food is essential to well-developed, mature plants. Without crucial nutrients, plants can’t thrive with just water and sunlight alone. To help you decide on the best plant food for your garden, we’ve created this list of the best ones available.

Proper plant nutrition depends on three nutrients mixed in with your soil — nitrogen, phosphorus, and potassium. In a nutshell, nitrogen keeps leaves and stems green and alive; phosphorus helps the plant mature and develop; and potassium promotes crucial plant processes like photosynthesis. Other nutrients help plants grow to their full potential, but plant feeding actually depends on a plant’s specific needs. For instance, a flower has different needs from a young tree. So let’s check out the best plant foods to see which type might be best for you.
