1、 What flowers are suitable for

Urea is a kind of fertilizer with the highest nitrogen content. It is a neutral nutrient. It can be applied to most soils and flowers. It is easy to preserve and use. In particular, some plants cultivated at home for viewing leaves, such as loose tail sunflower, fortune tree, green rose, etc., need to be applied in time in order to maintain the green and luster of the leaf surface. It can also adjust the amount of flowers and increase the amount of flowers in the coming year, such as peony, rose and white palm. However, pay attention to the concentration. If the concentration is too high, the plant may grow in vain

2、 Method of use

1. Root: improper use will cause damage, waste nutrients and reduce the utilization rate. It is best to dig a small hole about 15-20cm away from the flowers, bury an appropriate amount of fertilizer in it, and then bury it with soil. It is best to apply water after an interval of 7 days

2. Foliar: urea can be dissolved in water and is easily absorbed. The loss is small. It is very suitable to be used as foliar fertilizer and sprayed on the foliar surface with clean water. The application time is selected at 4 p.m. every day. At this time, the pores open, which is conducive to full absorption
