Newly dug trees should be planted in cultivation pots, cultivated for 1 year, and then planted in ornamental pots. The decorative basin can be of medium-deep type. Loose, neutral or slightly acidic topsoil, such as mountain soil and humus soil, mixed with a small amount of coarse sand, should be used as basin soil. The pond soil containing humus is very suitable for planting black pine after being crushed by selenium.

When potted, you can cut the pine branches with needles in half and cut off the roots that are too long. When serving, the roots should be stretched tightly, and the roots should not be hugged together. After planting, water it and place it in a cool and ventilated place.

Modeling is mainly based on climbing, supplemented by scissors. The lower branches of the trunk Dozza into drooping branches, ups and downs, or tied into flat branches. The branches of the trunk are wheel-shaped, so the thick branches of 1 should be selected, and the upper and lower branches should be staggered to avoid parallel branches.

Climbing and pruning are mostly carried out during the dormant period. Pruning during the growth period will easily lead to the outflow of turpentine from the wound, which will affect the growth. In this period, we usually only do climbing and picking buds to control its growth, making the branches thicker and the internodes shorter. When the branches grow, we can pick new buds before the needles are born. ] When controlling the growth of branches, the whole bud should be picked. Pruning technology can be used to promote branch germination during dormancy, that is, before standing. Leave some needles when trimming. If you don't leave a needle, this technique will not sprout and die easily.

Black pine likes to dry, so the daily pot soil should not be too wet, and it will be permeable when it is dried. Proper water control during the growth period can make branches stout, internodes dense and needles short. When the temperature is high in summer, you can often water the needles to help them grow.

The newly dug stumps have been cultivated for 1 year. When changing pots, the stumps should be turned out of the original pots in combination with soil changes, and 2/3 of the old soil should be removed to promote the stumps to take root and make them flourish. Too long roots, old, rotten and diseased roots should be cut off when turning over the old pots. 2 Change pots? Advance before the branches sprout.

The main disease of black pine is leaf rust, which can cause defoliation, affect growth and even avoid death. Spraying 65% wettable thiram magnesium 3000 times solution can prevent and control it. Most of the pests are red spiders, scale insects and aphids, and 40% dimethoate milk can be sprayed 1000 times.
