I. How to use foliar fertilizers for flowers
When flowers grow, foliar fertilization can be used to provide them with the nutrients they need for growth and flowering. The use of fertilizer is very simple:
1. According to the type of plant, choose the appropriate type of foliar fertilizer. If it is a foliar fertilizer prepared by yourself, pay attention to control the concentration.
2. Dilute the foliar fertilizer to the required ratio with hydroponic nutrient solution or other substances.
3. Put the foliar fertilizer into the watering can, and spray it on the leaves of the flowers with the watering can, once every 10 days.
Second, whether to spray foliar fertilizer on the front or the back of the leaves
When spraying foliar fertilizer on flowers or plants, many friends are not sure about the foliage Whether the fertilizer should be sprayed on the front or the back of the leaves, some friends have always only sprayed the front, but this is actually wrong.

When foliar fertilizer is sprayed on the back of the leaves, the plant will absorb it faster, especially some fruit trees, such as peach and pear trees, which have a waxy layer on the front of the leaves. Very thick, about 4 times thicker than the back of the leaf.
Therefore, to sum up, when applying foliar fertilizer to plants, both the front and the back should be sprayed, and the back of the leaves should be sprayed as much as possible, so that the foliar fertilizer can be better absorbed.
Three, can foliar fertilizers be used to irrigate roots?
It is generally not recommended to use foliar fertilizers to irrigate roots.
Foliar fertilization and root irrigation are all to allow plants to absorb fertilizer. Foliar fertilizers are generally foliar spraying, which has the advantages of fast absorption, low dosage and high efficiency. Foliar spraying leaves Fertilizers can be quickly absorbed by plants; however, using foliar fertilizers to irrigate roots has very little effect and is prone to waste.
