Every spring sowing, we need to dig out the cactus, clean up the soil on the root, and then cut off all the small roots on the main root in turn, leaving only the main root, and then clean the main root. Place it in a ventilated place for about 1-2 days, and then bury it in the basin soil. In addition, the basin soil can be replaced in the process of pruning, which is more conducive to the healthy growth of cactus.
Cactus in the exchange of products should be cut off part of the old roots, rotten roots. Then place it in a ventilated place for about 4-5 days before potting. Do not plant too deep and keep it flat with the soil surface.
In order to avoid the phenomenon of rotten roots, the newly planted cactus should not be watered, only spray 2-3 times a day. After half a month, water will be changed from less to more. After a month, new roots can be sprayed and water will be increased gradually.
Cactus can carry on Cutting Propagation and grafting propagation.
Cactus is prone to diseases and insect pests, especially in the summer when the high temperature and poor ventilation will cause a variety of diseases and insect pests. If encountering diseases, you can spray carbendazim or tobujin solution; insect pests can spray Omethoate, and the best way to control diseases and insect pests is outdoor.
