High Phosphorus Fertilizer?

A phosphorus fertilizer is typically used to create a copious cascade of blooms on vines and bushes to create a lush garden, indoors or out. Phosphate is a key element in plants that need to flower or produce fruit. It promotes good root development. Phosphate is combined with calcium to create calcium phosphate. This form of phosphate fertilizer requires natural microbial and chemical processes to be released into the soil. A soil test can give you a good idea of what you are working with before you begin adding any type of fertilizer. Dig up 2 teaspoons of soil from the garden and add ½ cup of vinegar. If the soil beings to fizz, then it’s on the alkaline side, with a pH of between 7 and 8. The calcium and phosphorus bond is stable, so it won’t burn the plants as other fertilizers will if too much is added to the soil. This is particularly important to do with a garden bed that has previously used soil.
