1, environmental mutation leads to the yellowing of mint leaves: 1. The leaves turn yellow due to excessive watering, and it is not easy to be excessively wet at ordinary times. Too wet soil is easy to accumulate water, root rot and yellow leaves. 2. The soil slab is hard and impermeable, and the poured water can't penetrate into the soil layer, which leads to the fact that most roots can't absorb water and nutrients, resulting in dehydration and malnutrition of leaves and drooping of yellow leaves.

Solution: It is best to keep the soil dry and water it, which is beneficial to the growth of roots and leaves are not easy to turn yellow. The best way is to loosen the soil properly, which is beneficial to soil loosening, ventilation, drainage and root growth.

2. Too much watering causes the mint leaves to turn yellow (water yellow): Pay attention when watering wrinkled mint. Do not water the soil when it is dry. If it is dry, it will be watered. The water used can be clean water, preferably rice washing water at home, which is nutritious and water-saving.

Solution: Just pick the yellow leaves and be careful not to water them too much. Mint has a strong vitality. Even if the leaves and stems wither for a while, don't think it's dead. Cut off the withered parts and wait for new buds. Don't throw them away!

3. Long-term water shortage causes the leaves of mint leaves to turn yellow (drought yellow): wither, zoom, and the leaves become castrated.

Solution: Mint is a good plant. Usually, the failure of planting is due to lack of water, which makes the plants die. However, if there are white objects on your plants, it may also be caused by pests and diseases. If the indoor balcony does not open the window, the ventilation is not good, and pests and diseases are more likely to occur. Next time it happens, it is suggested that the stem can be trimmed to 1/2, and some insect repellent, such as neem oil and lavender essence, will generally grow healthy new branches again. If water and pests are well controlled, plus good light and ventilation, mint can grow well.

4. Air drying leads to yellowing of mint leaves: the tip is dry or the leaf edge is brown.

Solution: Attention should be paid to increasing air humidity by spraying water and covering with plastic film.

5, insufficient sunlight leads to yellowing of mint leaves (lack of light yellow): long-term darkness is easy to cause symptoms of excessive growth of yellow leaves.

Solution: It is best to put it indoors in a sunny and ventilated place to reduce the problem of yellow leaves, and it is better to move out of the sun every morning and evening 1-2 hours.

6, the temperature is too high, causing the mint leaves to turn yellow: the room temperature in winter is too low, and flowers that like high temperature are often vulnerable to cold damage, causing the leaves to turn yellow, and in severe cases, they will die.

Solution: Please pay attention to adjust the room temperature in time. It needs to be moved to a well-ventilated shade in time.

7. Low temperature leads to yellowing of mint leaves: if the room temperature is too high, the transpiration of plants is too strong, and the water and nutrients in the roots are in short supply, it will also make the leaves yellow.

Solution: Please pay attention to adjust the room temperature in time.

8. Excessive fertilization of mint leaves leads to yellow leaves (fat yellow): the new leaves are thick and uneven, and the old leaves are brown and fall off.

Solution: Stop fertilization immediately, increase the amount of watering, and let the fertilizer flow out from the drainage hole at the bottom of the basin, or immediately pour the basin, rinse the clods with water and replant them in the basin.

9. Rotten roots lead to yellowing of mint leaves: the leaves are longitudinally wrinkled and deformed.

Solution: Find out the rotten roots and cut them off with scissors.

10. Yellow leaves of mint leaves caused by pests and diseases: Leaf spot caused by fungi and other bacteria is easy to cause local necrosis of leaves and yellow spots or patches appear. In severe cases, the leaves are completely yellow and fall off, and yellow-green spots appear after the leaves are infected by mosaic virus; Suffer from scale insects, red spiders, etc. The leaves will also become partially yellow and withered, or even the whole leaves will turn yellow and fall off.

Solution: spray them all in time.

Maintenance experience of Bian Xiao Mint;

1. mint must be fully sunny and can be placed on the windowsill for a while at noon.

2. When it is dry, water it again, that is, there is a drop of water at the bottom of the basin.

3. Mint needs rich and soft soil. If the flowerpot is too small, or the soil is too small to keep up with the nutrition, it will grow slowly. Therefore, it is very fertile soil with strong air permeability and water permeability. Common garden soil, humus soil. Add some chicken manure fertilizer and it will be fine. It is not picky about the soil.

4. Prune regularly, and it is no problem to make tea with its leaves. The more you trim it, the more lush it will be. You often loosen the soil, or add some soil, or fertilize it, it will grow faster. Be sure to put it in a ventilated place on the balcony.

It is best not to plant it in a flower bed, because it will occupy the whole flower bed area. Grab nutrients from other plants.
