Pruning and shaping of potted bluegrass flowers: When bluegrass flowers have old leaves and yellow leaves, especially those with pests and diseases, they should be cut off in time. Pseudobulb without leaves should not be cut off when styling, because it can store nutrients and moisture, which is beneficial to the growth of orchids. After the bud is unearthed, only one bud can be left per plant, and the rest should be cut off. If there are too many buds to compete for nutrition, it will not only grow well, but also affect the next year's flowering. After two weeks of flowering, cut off the flowers to prevent pollination and fruiting, which will affect the next year's flowering.
