jacking
Topping should be done at seedling stage, and the trunk length should be controlled between 15-20 cm. Topping can remove the top advantage, promote the growth of lateral branches, make plants more beautiful and more convenient for modeling. You can also top the side branches, which will also appear more lush.
Pruning in growth period
The growth period of orchids should be pruned, usually 7 days before and after flowering. Before flowering, the buds can be properly thinned or smeared, which can reduce the consumption of nutrients and make the flowers bloom more evenly. After the flowers wither, the residual flowers should be cut off in time to accumulate certain nutrients for the continued growth of plants.
Disease pruning
If orchids get sick, the branches and leaves will often start to wither, so pruning is needed at this time. Cut off diseased branches and spray carbendazim to avoid recurrence. Then put it in a semi-shady place for maintenance, and when the wound is dry, the plants can recover quickly. In addition, the cut branches and leaves must be destroyed to avoid infecting other plants.
