How to use potassium dihydrogen phosphate to make flowers grow well (how to fertilize flowers at home)

Potassium dihydrogen phosphate is a phosphorus-potassium binary compound fertilizer, which is mainly used to supplement phosphorus and potassium elements.

Potassium dihydrogen phosphate is more commonly used in flower cultivation, but potassium dihydrogen phosphate should not be used indiscriminately. When using it, you should pay attention to the time of use, method of use, concentration, etc., which are explained in detail below.

1. Usage time of potassium dihydrogen phosphate

Potassium dihydrogen phosphate contains 52% phosphorus and 34% potassium, and its main use is to supplement phosphorus and potassium fertilizers. The three elements that plants need the most for nutrients are nitrogen, phosphorus and potassium, and the needs for nitrogen, phosphorus and potassium are different at different growth stages.

In simple terms, plants need more nitrogen during the growth stage of branches and leaves, and more phosphorus and potassium during the flowering stage. Therefore, potassium dihydrogen phosphate is generally used in the bud and flowering stages of plants.

2. Usage of potassium dihydrogen phosphate

There are two ways to use potassium dihydrogen phosphate, one is direct root irrigation, the other is foliar fertilizer. From the perspective of plant absorption efficiency, foliar spraying is the best, and root irrigation will cause a waste of some fertilizer.

Another factor to consider when using it is that potassium dihydrogen phosphate is generally used during the flowering period. Therefore, for some plants after flowering, direct foliar fertilization will inevitably spray onto the flowers, causing them to rot.

Therefore, if you want to add fertilizer after flowering, you can use root irrigation.

3. Use concentration of potassium dihydrogen phosphate

The concentration of potassium dihydrogen phosphate must be paid great attention to. It must not be too high. Generally, as a foliar fertilizer, the concentration can be controlled at 0.2-0.3%. As a root irrigation, the concentration can be slightly higher, but not more than 0.5%.

4. Do not use potassium dihydrogen phosphate alone

Potassium dihydrogen phosphate is just a binary compound fertilizer of phosphorus and potassium, which can only provide phosphorus and potassium elements, but not other elements. Plant growth requires not only phosphorus and potassium, but also nitrogen fertilizer and some trace elements.

Therefore, potassium dihydrogen phosphate cannot be used alone to fertilize flowers. Potassium dihydrogen phosphate only supplements the deficiency of phosphorus and potassium before and after the flowering period. Other types of fertilizers should also be used regularly.
