Using potassium dihydrogen phosphate wrong for your flowers? The correct way makes leaves dark green and branches full of blooms

Every gardener knows that potassium dihydrogen phosphate has extraordinary effects when used on flowers: it can boost photosynthesis, make stems thick and strong, develop a robust root system, promote flower bud differentiation, produce more and bigger flowers with vivid colors, and extend the blooming period. But potassium dihydrogen phosphate is not an all-purpose fertilizer. Some flower growers think that if their plants are not growing well, a little potassium dihydrogen phosphate will fix them, but after using it the results are not obvious.

First, let us understand what each of the nitrogen, phosphorus and potassium elements does for flowers. Nitrogen promotes lush growth of stems and leaves with a deep green leaf color. Phosphorus promotes a well-developed root system, enhances cold and drought resistance, and promotes flower bud differentiation. Potassium promotes robust plant growth, hard and sturdy stems, strengthens resistance to pests and diseases, and prevents leggy growth. In summary, potassium dihydrogen phosphate contains only phosphorus and potassium, and it is very effective at promoting flower bud differentiation, root development and strong plants. But it has little effect on thin, small plants with yellowing leaves.

Thin, small plants with yellowing leaves are lacking nitrogen. Nitrogen is a component of nucleic acids and chlorophyll, and nitrogen has a close relationship with the chlorophyll content in leaves. Slow growth, short stature, thin and small leaves, and chlorotic yellowing leaf color are all caused by a lack of nitrogen. No wonder many flower growers see no obvious effect after using potassium dihydrogen phosphate; most of them are using it the wrong way. Some flower growers even buy fake liquid potassium dihydrogen phosphate. Real potassium dihydrogen phosphate looks like white crystals or powder; there is simply no such product as a liquid version. So when buying, you must tell the real from the fake.

The correct way to use potassium dihydrogen phosphate is together with urea. Before flower bud differentiation, mix 1 gram of potassium dihydrogen phosphate and 1 gram of urea with 1000 grams of water to make a 0.2% fertilizer solution for spraying on the leaves. Spray both the front and back of the leaves, once every 10 days, for a total of 2 to 3 sprays. You can also bury half a spoonful (2 grams) of urea into the soil in the pot a bit away from the roots, and spray the leaves with a 0.2% potassium dihydrogen phosphate solution. Do this and you will see results within a few days. It can make the flowers' branches and leaves vigorous and produce abundant blooms.
