This is a common phenomenon in the cultivation of meat. Specifically speaking, it refers to the originally compact shape. Suddenly, the stem and leaf extend wildly. The leaf droops, and the branches and leaves become very slender, but very weak. This kind of phenomenon can cause the ornamental of the plant to reduce, it is the phenomenon that breeders are most reluctant to see.
(1) the first possible reason is that the soil contains too much N fertilizer. We all know that N element can accelerate the cell division of plants. If photosynthesis can't keep up with the speed of cell division at this time, then the plant will grow in vain, and even fall down easily. If that's the reason, then we need to adjust the number of times we use fertilizer, and the type of fertilizer. Properly reduce the frequency of topdressing, or change the type, it is OK
(2) the second reason may be too much water. If too much water is absorbed by the plant, and the sun is weak at this time, then these water can not be consumed by the plant, they will accumulate in the stem position, where the vacuole will expand, resulting in excessive growth. If it is for this reason, then we should adjust the watering, less water, so that the soil is half dry and half wet.
(3) the last reason is lack of light. For this reason, we can put it on the balcony directly to receive the light, not on the windowsill behind the glass.
