Generally, the tea areas in the middle and lower reaches of the Yangtze River should be applied in the middle of October, and the tea areas in the south can be postponed appropriately.
The amount of basal fertilizer application depends on the age of the tree and the productivity of the tea garden. Generally, 250-300 kg of biological organic fertilizer is applied to tea garden acres.
The base and method of fertilizer application in tea garden are determined according to the tree age:
1-2 years old tea trees are opened at a distance of 10-15 cm from the root neck, about 15 cm wide and 15-20 cm deep.
Tea plants of 3-4 years old are applied with bio-organic fertilizer at a depth of 20-25 cm at a depth of 35-40 cm from the root neck; adult tea gardens are ditched along the vertical vertical position of the crown and the depth is 20-30 cm;

The third time was after the summer tea was picked or when the growth of summer shoots stopped basically.
For tea gardens with high temperature or high yield, a fourth or more top dressing is required, and the top dressing time should be determined according to the actual situation. 100 kg of bio-organic fertilizer was used for topdressing of tea gardens per acre. Young tea gardens were ditched 10 cm away from the outer edge of the tree canopy. Adult tea gardens were ditched vertically along the canopy.
