The nursery soil should be well drained and deep loam in nature with pH of 4.5 to 4.8. The rooting medium should be tested for pH and free from nematode infestation.

Manuring should be done 2 months after planting. Phosphorus should be applied at 80 – 100 kg/ha as rock phosphate once in a year by placement at 15 – 25 cm depth upto the first pruning and thereafter once in two years. N: K ratio of 2: 3 should be adopted for the
first 3 years and a ratio of 1: 1 thereafter may be followed.

Application of fertilizers should be done before the onset of monsoon. Fertilizers should be broadcast around the drip circle avoiding contact with the collar.
To induce more laterals, centering should be done 3 – 5 months after planting. The main leader stem should be cut, leaving 8 – 10 matured leaves.
First tipping at a height of 35 cm and second tipping at 60 cm respectively from ground level.
To maintain convenient height and vegetative growth and to remove dead and diseased branches, pruning is done.
Area to be pruned every year = Total extent of the garden/Pruning cycle
Pruning interval = (Elevation in feet / 1000) + 1
Pruning should be done in April – May and August – September respectively in S.W and NE monsoon areas.
The whole bush should be cut near the ground level less than 30 cm with a view to rejuvenate the bushes.
Formation pruning of young tea at 30 to 45 cm (12″ to 18″) for proper spread of bushes.
To check the bush growing to an inconvenient height this type of pruning is done in order to stimulate new wood and to maintain the foliage at lower levels less than 60 cm.
Pruning depends on the previous history of the bush raising the height of medium pruning by an inch or less to manageable heights for plucking (less than 65 cm).
This is the lightest of all pruning methods. Remove the top 5 – 8 cm new growth to obtain a uniform level of pruning surface (more than 65 cm).
Pollarding of shade trees should be done prior to heavy rains at a height of 8 – 10 m
from the ground level.
Cutting the erect type branches on the laterals in shade trees before monsoon season.
