Aloe Vera is a tropical herb. It is easy to breed and has a high survival rate. Many people like to breed aloe vera in the office or at home. But improper maintenance will make aloe leaves yellow. Let's understand the reasons and solutions for aloe leaves yellow.
The reason analysis and treatment method of aloe leaf yellowing: 1. The environment mutation causes aloe leaf yellowing: the reason of the environment mutation, the sudden change of temperature, humidity and light is too big, or the root needs to be slowed down when the basin is changed, and the leaves are yellowing due to the partial acid or alkali of the soil.
Solution: minimize the degree of environmental change, and wait for it to adapt.
2. Too much watering causes aloe leaves to turn yellow (watery yellow): after being damaged, the young leaves first turn pale yellow, and then the old leaves gradually turn yellow.
Solution: at this time should immediately control watering, stop fertilization, and often loosen the soil, so that the soil ventilation is good.
3. Long term water shortage will cause aloe leaves to turn yellow (dry yellow): it will cause the leaves to be dull and lusterless, and the leaves will wilt and droop. First, the lower leaves were aged and withered from bottom to top.
Solution: at this time, appropriate watering is needed to make it gradually recover and then transfer to normal water and fertilizer management.
Aloe, which is short of water for a long time, is dark and yellow
4. Insolation causes aloe leaves to turn yellow (burn yellow): it is very easy to cause young leaf tip or edge to scorch, or yellow leaves to fall off.
Solution: move to a cool place with good ventilation for maintenance.
5. Air drying causes aloe leaves to turn yellow: the tip of the leaves will often dry and turn yellow, or the edge of the leaves will be scorched, or the leaves will be scorched and curled.
Solution: spray the branches and leaves with warm water close to the room temperature to increase the air humidity.
6. Lack of sunlight causes aloe leaves to turn yellow (lack of light yellow): will gradually lead to weak growth, thin and yellow leaves.
Solution: move the potted flowers to the sunny place.
7. Too high temperature causes aloe leaves to turn yellow: it is very easy to cause the tip or edge of young leaves to scorch, or yellow leaves to fall off.
Solution: move to a cool place with good ventilation for maintenance.
8. Too low temperature causes aloe leaves to turn yellow: the room temperature is too low in winter, and the leaves will turn yellow if slightly damaged by freezing.
Solution: adjust the room temperature according to the situation in time.
9. Too much fertilizer causes aloe leaves to turn yellow (fat yellow): new leaves will appear to be fat, but most of them are uneven, and the old leaves will be burnt yellow and fall off.
Solution: stop fertilizing immediately, increase the amount of water to make the fertilizer flow out of the drain hole; or immediately pour it into the basin, wash the soil lump with water and then replant it in the basin; or remove part of the old soil and replace it with new culture soil.
10. The long-term lack of fertilizer leads to the yellow leaves of aloe (lack of fertilizer yellow): the lack of nitrogen and other nutrients in the soil leads to the thin and yellow branches and leaves.
Solution: pour the pot in time, change into a new fertile and loose culture soil, and gradually increase the application of compound flower fertilizer or thin liquid fertilizer.
11. Rotten root causes aloe leaves to turn yellow: the color of tender leaves becomes light, yellow, etc.
Solution: remove the rotten roots in time and put them in a ventilated place to cool and dry. After the wound is healed, return to the basin. Pay attention that there should be no water in the basin.
12. Diseases and insect pests cause aloe leaves to turn yellow: yellow spots or plaques appear, and the whole leaves will wither and fall off in serious cases.
Solution: when diseases and insect pests are found, tobuzin or dimethoate should be sprayed in time for control.
Aloe leaves with yellow diseases and insect pests: 1. Aloe like to grow in loose soil with good drainage performance and not easy to harden. The general soil can be mixed with some gravel ash, for example, it is better to add rotten leaf ash.
2. During the vigorous growth period, the nutrients in the soil are constantly absorbed by the plant, and if the fertilizer is not applied in time, the growth of aloe will be affected. Organic fertilizer is generally slow in fertilizer effect, so it is too late to apply fertilizer after aloe growth is affected. Do not apply fertilizer too much at a time. Do not contaminate the leaves. If contaminating, wash with clean water.
