Usage and dosage of flower base fertilizer and top dressing

The fertilizer applied to the soil before planting or above the pot is called base fertilizer, generally dry powder, such as poultry manure, bone meal, bean cake, etc. It is required to have more nitrogen, phosphorus and potassium components, which is beneficial to improve soil structure. And can continue to decompose to ensure the constant need during the long growing period. The base fertilizer must be decomposed. When planting flowers, it should be applied under or around the roots, but it should not be in direct contact with the roots. When the potted plants are used, they should be determined according to the type of flowers. The base fertilizer is the basic nutrient for flower growth and should be taken seriously.
During the growth of flowers, due to the lush growth of the foliage, a large number of flowering results, consume a lot of nutrients, need to add fertilizer at any time, this is called top dressing. Most of the topdressing is based on liquid fertilizer, which is beneficial to soil absorption and root utilization.
Topdressing can apply both inorganic fertilizers and organic fertilizers. Inorganic fertilizers must pay attention to the appropriate concentration, usually 0.1~0.5%, so as to avoid the harm caused by excessive concentration; organic fertilizers must be fully decomposed, and the principle of “small meals” should be mastered.
