- Synthetic fertilizer: Synthetic fertilizer is composed of chemical compounds that provide essential nutrients to plants in a concentrated form.
What Does Fertilizer Do?
Fertilizers provide plants with the essential nutrients they need in order to grow and flourish, this includes nitrogen for healthy foliage growth, phosphorus for strong root growth and disease resistance, and potassium for strong flower development.
When to Apply Fertilizer to Roses
