Urea is a kind of fertilizer with the highest nitrogen content. It is a neutral nutrient. It can be applied to most of the soil and flowers. It is easy to preserve and convenient to use. In particular, some of the plants raised at home for leaf observation, such as the scattered tail anemone, Money Tree, pothos, etc., need to be applied in time in order to maintain the green and luster of the leaves. It can also adjust the amount of flowers, so that the next year's increase in the amount of flowers, such as peony, rose, Spathiphyllum, etc. can be used, but pay attention to a good concentration, too high may cause the plant to grow in vain.
1. Root: improper use will lead to damage, waste of nutrients and reduce the use rate. It's better to dig a small hole about 15-20cm away from the flowers, bury a proper amount of fertilizer in it and then bury it with soil, and it's better to apply water after 7 days.
2. Leaf surface: urea can be dissolved in water, which is very easy to be absorbed, and the loss is small, so it is suitable to be used as leaf fertilizer, mixed with water and sprayed on the leaf surface. The application time is chosen at 4:00 p.m. every day, when the pores open, it is conducive to full absorption.
