Potted plants not blooming or growing roots? Your pot may be lacking this

During the high-temperature summer and the autumn growing season, water demand in the morning and evening is high. Watering too much and too often will cause nutrients in the pot to be lost faster, leading to poor growth to a greater or lesser degree. How can nutrient loss be prevented? Flowers and plants just won't bloom and are prone to root rot? What can be done about this?

The above phenomena may be because your flowerpot is lacking this: potassium dihydrogen phosphate! For people who often grow flowers, there should be a lot to know about it, but many beginners know very little about its effects. Potassium dihydrogen phosphate is essential for growing flowers. It is quite outstanding at improving plants' disease resistance and cold resistance. It also promotes root growth, keeps plants dwarfed and compact to maintain their shape, and is the most effective fertilizer for promoting flowering.

Why potassium dihydrogen phosphate?

There is a saying about fertilizing: nitrogen grows leaves, potassium grows roots, and phosphorus is sprayed for flowering and fruiting. Flowers and plants need to grow roots, grow leaves, and bloom, so flower fertilizer is certainly indispensable. As the name implies, the advantage of potassium dihydrogen phosphate is its high content of phosphorus and potassium, with a small amount producing obvious results. Potassium dihydrogen phosphate is a binary compound fertilizer. Its main components are: phosphorus pentoxide 52.2%, dipotassium oxide 34.02%. Its main component is phosphorus, followed by potassium. Potassium dihydrogen phosphate is generally best used in August and September.

1. It enhances its own stress resistance and makes the root system well developed, thereby reducing the occurrence of root rot.

2. It can promote photosynthesis. Potassium plays a role in enhancing photosynthesis in plant growth, accelerating the manufacture and transformation of nutrients.

3. It can buffer changes in soil acidity and alkalinity, stabilize the pH value of the soil, and promote the growth and reproduction of microbial flora in the plant root system.

Correct methods for using potassium dihydrogen phosphate

Potassium dihydrogen phosphate can be directly absorbed and utilized through stomata and has a very good effect during the flowering period and fruit enlargement period. However, potassium dihydrogen phosphate contains phosphorus and potassium and nothing else, so it still needs to be applied in combination with nitrogen fertilizer.

It is recommended to use the Guoguang brand's Run'erjia 1 kg, about 25 yuan online. Note especially that Guoguang is a major domestic brand of agricultural supplies, genuine and guaranteed. In potassium dihydrogen phosphate, Guoguang has two products. One is for agrochemical use and is called Guoguangjia. For gardening use, choose Guoguang Run'erjia. The ratios also differ for different fertilization methods: dilute 1:1000 for foliar fertilizer, and dilute 1:2000 for root drenching.

When using it, pay special attention to fertilizing in the early morning or evening, avoiding high temperature and strong sunlight, otherwise the concentration will rise instantly and fertilizer burn is likely. In addition, stop fertilizing during the dormant period and flowering period. Be sure to spray both the front and back. The underside of leaves has many stomata, so fertilizer is more easily absorbed.

The good and the bad are mixed, so flower lovers need to keep their eyes open!

The disadvantage of potassium dihydrogen phosphate is that there are too many fakes on the market, and many use magnesium sulfate as a substitute. You need to carefully identify it when buying. Genuine potassium dihydrogen phosphate is expensive: 400 grams costs about 14 yuan, while fake potassium dihydrogen phosphate on the market sells for only 1-2 yuan.

Pay special attention: if it is labeled "compound type", "improved type", and so on, these are also not genuine. Potassium dihydrogen phosphate is white odorless crystals; if you can smell an odor, it is also fake.

How to deal with fertilizer burn?

Beginners lack experience and inevitably fail to get the fertilizer amount right. If the concentration is too high, fertilizer burn will occur. Fertilizer burn changes more obviously than any disease or pest. Two to three hours after over-fertilizing, you will find the branches and leaves wilting listlessly, the leaf color losing green, quickly discoloring and turning yellow and limp, and the underground root system turning dark brown, with severe cases turning black and rotting.

Once fertilizer burn occurs, take the following measures immediately:

Wash the roots and change the soil. Immediately take the affected flowers and plants out of the pot and rinse the root system with clean water. At the same time, cut off the affected part of the root system and trim off part of the scorched leaf edges. Completely replace the growing medium, repot, and water thoroughly.

If the flowers and plants have weak root systems, pulling them up by the roots and washing them with water is certainly not suitable. Instead, watering or soaking should be used. Immediately water the affected plants thoroughly 2-3 times in succession to flush out the high-concentration liquid fertilizer in the pot, or place the entire pot of flowers and plants in water to soak for 1-2 hours, remembering to change the water during the process, so as to quickly reduce the liquid fertilizer content in the potting soil.
