How to divide the roots and pots of orchids

Orchids grow slowly and can not be rooted until every 3-Mel for 4 years, and Cymbidium should have 5-Mel and 6-clumps of leaves, and Cymbidium should have 8-Mel and 9-clumps of leaves before it can root. Turning the pot is controlled in the dormant period after anthesis. The types of spring flowering are before "the Autumn Equinox" to "heavy snow" or new buds sprout; those in summer and autumn should blossom during "Qingming Festival" to "Grain Rain". When the soil is slightly dry, the orchid plant is gently turned out from the basin, the soil is wet and easy to break the root, shake off the soil, cut off the residual roots, fallen leaves and dried false corms, and do not hurt the buds and flesh roots when cutting. The newly purchased seedlings should cut off the broken root, if the injured section is rotten, it must be cut to see the whitish tissue, then wash the root, place it in a cool place, and then split the root when the root color is white and dry. Find out the wide distance between the two bulbs, the cut and the injured section, all need to be coated with plant ash or charcoal powder to prevent decay. Both of the cut parts should have new buds. And cut off too many old roots to facilitate the development of new roots, and finally put on the basin.

It is best to use tile basin, purple sand basin, glaze basin should pay attention to drainage, magnetic basin had better not be used. The size of the pot is appropriate for the root of the flower to stretch in the basin. Potted soil should be fertile, loose, non-alkaline, pH between 5.5 and 6.5, mountain mud is a good soil for orchids, can also use self-made humus soil. Orchids are most afraid of water burst, so first put a few small stones and charcoal at the bottom of the basin, be careful not to block the basin hole, and cover it with plastic gauze, which is about 3mur4cm high. Then fill the coarse-grained soil, then fill the fine-grained soil to the waist of the basin, protrude like steamed bread, place the orchid in the middle of the basin, evenly distribute the roots, cover the fine soil and lift the orchid seedlings lightly, vibrate the flowerpot at the same time, closely combine the soil with the root, cover the fine soil again, and use your fingers to pick up the basin soil from the edge of the basin to the root system, compacting and compacting it, so that the center is slightly higher, and finally add a layer of bean stone, then water from the edge of the basin, leaving a cool and ventilated place for half a month. And then moved to the shade to the normal maintenance.
