Orchid leaves grow out why is it closed

Orchids are suitable for a good permeable environment. Its sex likes yin, avoid glare direct light. Avoid drying, like moist air environment. According to the physiological habits of orchids, 15-30 degrees is the most suitable for growth, while temperatures above 35 degrees are bad. Growth stagnation below 5 degrees is in a dormant state

The unearthed time of new buds of different orchid varieties is different. Take Chunlan as an example: new buds were unearthed from late May to late June, and some were unearthed in early August. The new buds unearthed in August can not be completed in the same year and continue to grow in the coming year, when the new buds are in a closed state. This state will be maintained from mid-June to mid-July, and the growth will begin to accelerate. Until November, the growth of leaves stopped.

In fact, careful observation, most of the orchid leaves are in a closed state, will gradually unfold with the growth of the leaves. At the same time, the leaves are not spreading for a long time, and there are reasons for rooting. However, there are also some abnormal phenomena due to uncomfortable environmental conditions, such as the adhesion of new and old leaves, which is mostly caused by insufficient air humidity.

For example, when the northern winter heating room is dry, this phenomenon will occur due to insufficient humidity; there will also be caused by insufficient root support for new buds, which is related to the coarsening of the plant material. This is very convenient, so it is better to let nature take its course. Don't break it with your hands, just touch it and break it. The leaves will rot if you are negligent in management.

The last reason is lack of phosphorus. The results showed that the growth of leaf buds was slow, the root was too late, and the leaf margin curled slightly. The root can be irrigated with 800 times potassium dihydrogen phosphate solution. Once every 10 days, twice in a row.
