What do the Numbers in 10-10-10 Fertilizer Mean?

Phosphorus is important for plant growth and development, particularly for root growth and the production of flowers and fruits. It also plays a role in photosynthesis and energy transfer within the plant.

It is also important for regulating water balance within the plant, which is critical for maintaining turgor pressure and preventing wilting.
