As long as the flower friends who have raised flowering plants at home, they must be no strangers to potassium dihydrogen phosphate as a fertilizer, potassium dihydrogen phosphate has a good flower-promoting effect, and is often used to promote the use of various flowers and plants.
Although the flower-promoting effect of potassium dihydrogen phosphate is good, it is not a test of the lark. If the timing is not right, it will not only not promote the development of flower buds, but also increase the burden on the plant and cause fertilizer damage. If the flowers and plants do not meet the 3 conditions, even if more potassium dihydrogen phosphate is used, it is difficult to have an effect. What are the 3 conditions? Let's take a look together~
1. Do not use only potassium dihydrogen phosphate
If plants want to flower, they need to absorb various nutrients, and phosphorus is one of the most important elements for flower bud differentiation. In order for flowering plants to obtain sufficient phosphorus, we need to supplement the soil with phosphorus by fertilization, and potassium dihydrogen phosphate is a single phosphorus and potassium fertilizer that contains very high phosphorus. Therefore, using it to fertilize flowers and plants has a good flower-promoting effect.
But plant growth buds are not only phosphorus involved, it also needs other nutrients, do not think that as long as you use potassium dihydrogen phosphate, everything is fine. If we only use potassium dihydrogen phosphate, we usually neglect to supplement the plant with other fertilizers, and over time, it will grow poorly due to lack of nutrients. The plant itself is weak and does not have enough nutrients to nurture the buds, so even if more potassium dihydrogen phosphate is applied, it will not flower.
2. Light promotes flowers
In order to nurture buds, flowers and plants need to have enough energy in addition to sufficient nutrients. The only way plants can get energy is through photosynthesis. Different varieties of flowers and plants have different requirements for light. Many flowering plants prefer plenty of light, such as lunar season, clematis, petunias, and so on. If such flowers are raised in a place with insufficient light and cannot absorb enough energy, the flower buds will not develop, and the use of potassium dihydrogen phosphate will not have a flower-promoting effect.
Of course, there are some flowers that belong to shade-tolerant flowers (also called shade-tolerant flowers), such as orchids, panies, African pansies, etc., which do not like bright light and need to be kept in darker places. But just because they don't like bright light doesn't mean they don't need light. In fact, these flowers just can't get direct light, but they need to be kept in a bright position and maintain sufficient soft scattered light to develop normally.
3. Prune and promote flowers
Proper pruning is also one of the ways to promote flowers. When the branches of the flower grow too long, the distance of nutrients from the root to the top becomes longer, resulting in untimely nutrient transport, which can lead to leaf litter or stiff seedlings. And if there are too many thin branches, they will also compete with the flowering main branch for nutrients, so that the main branch receives fewer nutrients, unable to provide enough nutrients for the flower buds, resulting in a decrease in flower volume.
In order to ensure that the flowers can bloom, we must prune the branches of the flowers and plants in time to keep the plant shape neat. After pruning, new shoots will grow more densely, which will increase the chances of flowering, while also helping the plant to better adapt to the potting environment. Maintaining moderate pruning is very important for the healthy growth and flowering of flowers.
