You'd better cut off the roots when changing pots. Orchids need to change the pot soil regularly in the process of reproduction. So do you want to cut the roots when changing pots? You don't need pruning at ordinary times, but if there are old roots, diseased roots and rotten roots, you need to prune them in time and only keep healthy roots. If not pruned in time, it will affect the absorption of nutrients by other roots.
Whether the roots of orchids are pruned or not, they need to be disinfected, soaked in carbendazim and taken out for about 15 minutes, which can disinfect the roots and reduce the occurrence of diseases. The remaining carbendazim can be poured into the soil to sterilize the soil, which can promote the growth of orchids.
After the orchid is changed, it needs to be moved to a cool environment to avoid light, otherwise it will affect the potted effect of the orchid. After a period of adaptation, plants can be maintained normally, and the light time is gradually increased to promote the vigorous growth of orchids.
After orchids adapt to the surrounding environment, they can be fertilized once, which can be farmyard manure or organic fertilizer, which can supplement nutrients for plants and promote their robust growth. In the process of orchid growth, they also need to supplement nutrition in time, especially foliar fertilizer, which can make their leaves green and shiny.
