What to do about the yellowing of the leaves of Pelargonium? the reason and solution of the loss of leaves of pelargonium

Pelargonium has a long flowering period and strong adaptability to the environment, so it is distributed all over the world. The plant is small and exquisite, beautiful in shape, very suitable for potted plants, so it is very popular with flower lovers. But how to raise a pot of geraniums? Geraniums often appear leaves yellowing, or even falling, how to solve it?

What if the geranium leaves turn yellow?

1. Abrupt changes in the environment lead to yellowing of geranium leaves: geraniums have a process of adapting to the new environment, just pinch off the large yellowed leaves and dry buds. Others adjust themselves.

2. Too much watering leads to yellowing of geranium leaves (water yellow): this requires immediate water control, loose basin soil in a ventilated and dry place to speed up evaporation. Or put the flowerpot on a stack of newspapers or dry peat and let the newspaper and peat suck out too much water from the pot as soon as possible. If the situation is particularly serious, the whole clod can be protruded from the basin and placed in dry peat or mound to make the water seep out quickly, and then replant it into the basin after the drooping branches and leaves are restored.

3. Long-term lack of water leads to yellowing of geranium leaves (dry yellow): in this case, it is necessary to adjust the watering method and use the principle of alternating dry and wet to water the geranium.

4. Sun exposure leads to yellowing (burning yellow) of geranium leaves: it is best to put them in the shade in summer.

5. Dry air leads to yellowing of geranium leaves: place in the ventilated place of transplantation.

6. The lack of sunlight leads to the yellowing of geranium leaves (lack of light yellow): because the yellowing leaves also hope that they can recover as soon as possible, they will absorb the nutrients accumulated by the plant itself, and it consumes more nutrients than it produces. So we don't have to worry too much, we just need to remove the yellow leaves in time.

The cause and solution of the loss of leaves of Pelargonium

1. Fall off naturally. The old leaves grow old and yellow and fall off naturally, the new leaves are still green, there is no other problem with the plant, and there are not many fallen leaves.

2. The weather is too hot. Geranium in the overheated environment, chlorophyll is destroyed, leaves collectively yellow, shedding more, serious new leaves whiten or yellowing does not grow up. At this point, the leaves get thicker and smaller, reducing the amount of light they receive. At this time, the geranium should be transferred to a cool place to reduce the time of exposure to sunlight, so that the plant type is relatively bald. If the weather turns cool, it will recover by itself.

The weather is too cold. Too cold will frostbite the leaves, and when the cells die, the leaves turn yellow and fall off.

4. Intermittent drought. Watering often waits for the soil to dry before watering, when the old leaves turn yellow and fall off in order to reduce water loss, and the watering rate can return to normal after the weather is cool and the watering rate is restored.

How do geraniums blossom more?

1. Reasonable fertilization and sufficient nutrients laid the foundation for the flowering of geranium. Need to consume a lot of nutrients when flowering, in the breeding of geraniums, need to apply more phosphorus and potassium fertilizer, so that more flowers, and bright colors.

2. Pruning in time. In the seedling stage of the geranium, the heart is about to be picked, so that its plant will grow a lot of branches, which will increase the number of flowers.

3. Proper lighting should be ensured. Generally, geraniums can be given 5 hours of light every day, which can promote flowering.

Matters needing attention in geranium culture

The main results are as follows: 1. There are different varieties of geraniums and different plant heights. Small plants should be selected for family planting. In addition, growth agents are needed to regulate them.

2. When the plant grows to 12 cm or 15 cm, spray chlorpromazine once a week for 2 consecutive times. Ensure that the light is 14-18 hours a day, which can effectively control the height of the geranium and provide high-quality potted flowers.

3. Special attention should be paid to watering. It is said that more plants will die, while the roots will rot easily if the temperature and humidity are high. Of course, the flowering time can also be controlled, and the full flowering period is generally from April to June, but if the temperature is raised appropriately in winter, it can blossom all the time from September in autumn to June of the following year.

As a perennial fleshy and evergreen shrub, geranium has high ornamental value. Planting geraniums in addition to daily watering, but also pay close attention to the growth status and diseases and insect pests of geraniums, timely detection and timely solution, geraniums can grow better, the more flowers will bloom.
