What if the leaves of potted sweet cherry turn yellow?

Potted fragrant cymbidium has high ornamental value, especially when several different varieties of fragrant cymbidium are implanted in one flowerpot. After all, there are many varieties of fragrant cherry, and different varieties often produce flowers of different colors. If multiple varieties are planted together in a flowerpot, the flowering period will certainly bring a lot of surprises.

However, Xiangxue orchid has a high temperature requirement under the growth environment, and it likes to grow in the environment of 15 ℃-20 ℃, and it is neither heat-resistant nor cold-resistant. When the temperature in the growing environment exceeds 20 ℃, the plant may go into dormancy, and when the temperature is as low as 5 ℃, it may be frostbitten. Perhaps this is one of the reasons why many potted friends will not choose this kind of plant as a family potted flower.

It can be seen that potted fragrant snow orchid is a kind of delicate flower plant, which needs our careful care to make it bloom as scheduled. And after the flowers fade and enter the summer, the plants will be withered and yellow. However, sometimes the leaves of the plant may turn yellow before the summer after flowering. So, what if the leaves of potted vanilla turn yellow?

First, burning yellow and lack of light yellow

Xiangxuelan likes light better, but it is a kind of plant suitable for short-day sunshine after all. If the light is too strong and the time is too long, its leaves are also easy to burn and turn yellow. Therefore, it is necessary to control the intensity and time of light exposure while providing light for it. Once the burning yellow phenomenon occurs, shading measures should be taken in time.

What is different from dry yellow is that the leaves of plants turn yellow due to lack of light, so it is generally necessary to put potted plants in places that are easy to receive light, usually let them bask in the sun more, but pay attention to control light intensity and exposure time, otherwise it may cause burning yellow phenomenon.

2. Dry yellow and lack of water yellow

If the humidity of the growing environment of Xiangxue orchid is too low, especially if the basin is in a state of lack of water for a long time, the original leaf edge is easy to dry up, and the old leaves turn yellow and fall off. This is a dry and yellow phenomenon caused by lack of water, so usually we should strengthen water management, generally pour water thoroughly, and often keep the basin soil moist, especially when the temperature is high to improve air humidity.

However, if we water too frequently and supply too much water, it will often cause too much dampness or stagnant water in the basin for a long time, which is easy to make the leaves of the plant yellow. This is mainly from the tip of the leaves began to turn yellow, and the extracted young leaves will also appear dark yellow and no sense of gloss, even the branches may also show a yellowish green. Therefore, once this situation is found, drainage measures should be taken in time to improve environmental ventilation and accelerate water evaporation.

Third, fat yellow and lack of fat yellow

The appearance of fat yellow in Xiangxue orchid is mainly due to too much fertilization or too high concentration in the process of maintenance and management, which will not only cause the yellowing of leaves, but also make the old leaves fall off. This is a performance of fertilizer damage, once it occurs, it is necessary to pour water in time to dilute and dilute the fertility in the basin soil, so as to reduce the fertilizer efficiency. However, if the fertilizer damage is serious, it is necessary to change the soil and replant it in time.

On the contrary, it is naturally lack of fat and yellow, because Xiangxue orchid likes the fertile soil environment, especially the flowering period needs to consume a lot of nutrients, so it is necessary to remove the residual flowers and cut off the flower branches in time after flowering to save nutrients. at the same time, we also need to do a good job of topdressing to supplement nutrients. Of course, it is generally necessary to apply some base fertilizer in the basin to ensure that the plant keeps growing normally and that the leaves are not yellowed due to lack of fertilizer. However, once the lack of fat yellow occurs, we should topdressing timely and scientifically.
