How to deal with the yellowing of the new leaves of Geranium? The causes and treatment methods of the yellowing of the new leaves of Geranium: generally, there are two reasons, one is the yellowing of the new leaves caused by lack of fertilizer, the other is the yellowing of the new leaves of Geranium caused by excessive humidity.
1. Generally speaking, it is rare that new leaves turn yellow due to lack of fertilizer, and it is easy for flower friends to rule out. If the plant grows weakly without topdressing for a long time, topdressing can be given appropriately.
2. In addition to the lack of fertilizer, there is also a very important reason for excessive humidity. The basin usually used is a deep basin (for example, a gallon basin). The upper part of the soil is relatively dry, and the bottom 1 / 3 of the basin is still very wet.
Treatment method: ventilation, can be planed off the surface of the soil, on the basis of soil moisture control watering.
Pelargonium new leaves yellow
Note: the withering or soft rot of geranium leaves is mostly caused by excessive watering, while the leaves are relatively strong but the edge is scorched, which may be due to insufficient watering. Generally, these two conditions can cause the leaves to fall off.
Pelargonium new leaves yellow expand knowledge - Pelargonium culture methods: 1, soil: Pelargonium adaptability is also strong, all kinds of soil can grow, but rich in humus sandy loam soil growth is the best.
2. Watering: Geranium likes dryness and dampness. It should not be watered too much in winter. If the soil is wet, the stem is tender, which is not conducive to the germination and opening of flower branches; if the soil is too wet for a long time, the plant will grow excessively, the position of flower branches will move up, and the leaves will turn yellow and fall off.
3. Sunshine: Geranium needs plenty of sunshine during its growing period, so it must be put in the sunny place in winter. The results showed that the light was insufficient, the stems and leaves were too long, the pedicels were soft, and the inflorescence was underdeveloped; the flower buds under weak light often failed to open and withered in advance.
