Basically, all dicotyledonous woody plants can be propagated by budding. But durian is different from other fruit pens in that it is not allowed to wrap all the buds. The main reason is that the bud on the bud of durian is easy to fall off. After two weeks, we can know whether it survived or not. If a flower survives, it should be cut at the top of its rootstock about 30 cm away from the bud to promote the rapid growth of the bud eye. In the future, the rootstock will also produce many rootstocks, but these rootstocks should not be cut off completely. One or two rootstocks should be left to promote the absorption of nutrients by the buds, and the remaining rootstocks should be pruned frequently.
The seedlings are most suitable for rootstock before the seeds have sprouted or become woody. After splitting, we need to cover the whole seedling with plastic bags, and put it in a cool place for 2 to 3 weeks. If the leaves used for scion don't fall off, it will be a success
Cutting needs to use 15 cm long branches, the diameter of which is about the same as the little thumb of a child. Several leaves are needed on the branches, each of which should be cut off by 2 /3 to reduce the evaporation of water. The lower end of the branch tip needs to be cut 1 cm obliquely from the bottom to the top. After applying rooting agent, it can be inserted into a wet cup. Put it into a greenhouse with weak light, and water it properly. After about 7 to 8 weeks, the leaves are not dropped, and the young roots have grown, so it can be put into a plastic bag.
Durian can also be propagated by grafting, but it is only suitable for a small amount of propagation. Besides, there are propagation methods such as air layering and ventral grafting of branches.
