Fertilization technology of privet
The time of fertilization should be in late March of the following spring, remove the sealed soil when applying fertilizer, dig a ring ditch 50 cm away from the tree trunk, 40 cm deep and 30 cm wide, and then apply farm manure. Ligustrum lucidum has low requirements for fertilizer application, more or less. After survival, fertilizers can be applied twice during watering from May to June each year, each time with 50Mel 100g of potassium dihydrogen phosphate or urea.

Control of Ligustrum lucidum
The wing pattern of the adult Ligustrum lucidum is slightly like a basket of woven texture, with a wingspan of about 9-10cm, which is a large moth. The larvae are gray-black or light-colored, and there are two dorsal horns on the 2nd and 3rd segments of the body when young, and the 2nd and 3rd segments are dilated when they are nearly old, and the color around the valve is bright. The larvae can make a cackling sound in their mouth when they are disturbed. Adult Eclosion from June to July. The hosts are privet, lobular wax, Japanese privet, white wax, sweet-scented osmanthus and so on. At present, it is the period of damage to the older larvae, which we are used to seeing.
