what type of fertilizer is the best
It is the basis for protein manufacture in plants and plays a major part in photosynthesis. For lawns, shrubs and leafy houseplants, a nitrogen-rich fertilizer is the best choice. When reading a fertilizer package, nitrogen will be the first in a series of numbers appearing with dashes between them. For example, a formula of 10-0-0 is a nitrogen-only fertilizer.
Phosphorous aids in the transfer of energy from one part of the plant to another and is responsible for strong root growth and healthy, hearty blooms. If you need to revitalize a blooming plant, a plant that isn't producing as much fruit as it should or a sparse lawn, a phosphorous rich fertilizer is the best choice.
