Why does geranium turn yellow?
Sometimes, as if the hostess did not try, but the favorite geranium still turns yellow and refuses to bloom. What could be the reason for these whims?
- Lack of fertilizer and plant nutrition can lead to yellowing of geranium leaves. This begins the process with yellowing of the lower leaves of the geranium. In order to stop this process, you need to regularly spray foliage with fertilizer, but not exceeding the norm. It is recommended to feed the plant for at least two weeks, until the signs of the disease disappear.
- However, an excessive amount of fertilizer and fertilizing is also not desirable. In this case, the plant may seem healthy and green, but the buds do not appear. You can eliminate this problem by watering the plant for several days without dressings. Excess fertilizer will be dissolved and descend to the bottom of the pot.
- The reason why geranium leaves turn yellow may also be cold nights. In this case, the leaves become red-red tint.This can occur when planting a flower on the street early, when the temperature at night is still low. It must be remembered that the temperature at night should not be below plus 5 - 10.
- The problem may lie in the intense heat in the daytime. Geranium can stop blooming for this reason. However, some geraniums easily tolerate summer heat. For each type, you must select the appropriate place.
- Another reason why geranium turns yellow may not be comfortable enough. If, for example, the soil contains too much nitrogen, or there is not enough light in the room. Provided that day and night temperatures do not differ. You need to put the geranium in a place where there is enough light and stop feeding for a while. Additional lighting may be required with fluorescent lights. Geranium requires daily about six hours of direct sunlight.
- Sometimes it is necessary to thin out the geranium or to plant it. Since the plant can deteriorate due to excessive thickening and strong growth.

Improper soil can cause geranium diseases. Suppose if it will be increased acidity. It is known that acidity is considered ideal for geraniums - pH 6.5.
Geranium leaves may turn yellow if the size of the pot is too small. In this case, it will be necessary to transplant the geranium in a larger pot.
