So I don't know how to deal with it, so what about the leaf yellowing of hydrangea? In fact, the solution is very simple, let's go with the editor to have a look.
First, the reason for the yellowing of hydrangea leaves
1. Direct illumination
Although hydrangea is in breeding, it also needs light, but it cannot be exposed to the sun for a long time, otherwise it will cause the leaves of hydrangea to turn yellow, so it is necessary to avoid direct sunlight during its growth. this is the only way to avoid the phenomenon of yellowing leaves.
2. Excessive fertilization
In the process of fertilizing hydrangea, excessive fertilization or raw fertilizer can easily burn roots, resulting in yellowing of leaves. If the plant does not change the soil for a long time, especially the lack of nitrogen fertilizer, the plant growth can not get enough nutrients, and the leaves lose green and yellowing.
3. Insufficient watering
Hydrangea likes wet and dark growth environment, and the demand for water is relatively high, so too little watering will lead to hydrangea leaves yellowing, and even lead to hydrangea root rot, so we should pay more attention in the process of maintenance.
4. The soil is alkaline.
If the hydrangea planting soil is alkaline or long-term alkali, neutral water, it will lead to soil iron deficiency, the leaf color will gradually turn yellow. The main performance is that the young leaves at the top of the branches are yellow, the old leaves are yellow, but the veins are still green. With the aggravation of the disease, the leaves of the whole plant will turn yellow, the leaf margin will be scorched, and wither gradually.
Second, what if the leaves of Hydrangea turn yellow
1. Reduce the lighting time
The light is too little, it is necessary to increase the illumination time appropriately, and it can be recovered slowly. If the light is too strong, you should immediately move the plant to a cool place to avoid direct sunlight. At the same time, the leaves and the surrounding environment are often sprayed with water to increase the air humidity, and the leaves gradually return to green.
2. Watering should be appropriate
When fertilizing too much, you should immediately stop fertilizing and pour a small amount of water. Or directly remove the plant from the pot, wash the plant with clean water, change the soil and replant it. If the leaves turn yellow due to too little fertilization, change the soil and apply fertilizer in time, and pour thin liquid fertilizer once every 10 days, the leaves will gradually turn green.
3. Replanting and breeding
When fertilizing too much, you should immediately stop fertilizing and pour a small amount of water. Or directly remove the plant from the pot, wash the plant with clean water, change the soil and replant it. If the leaves turn yellow due to too little fertilization, change the soil and apply fertilizer in time, and pour thin liquid fertilizer once every 10 days, the leaves will gradually turn green.
4. Change the pot and soil to prevent the leaves from yellowing
When planting or changing the soil, adding sulfur powder to the soil can ensure that the soil is acidic and its validity can be maintained for 2-3 years. The leaves flourish in spring and autumn. Applying alum fertilizer and water once every 15 days can prevent the occurrence of plant yellowing and make the leaves bright and green.
Conclusion: through the detailed introduction above, I believe we already know the reasons for the yellowing of hydrangea leaves, which is usually caused by too strong light, so it is best to raise hydrangea in a dark and damp place in the process of maintenance. in order to make hydrangea leaves green again, now flower friends already know what to do about hydrangea leaves yellowing.
