Moisture management. The blackening of the leaves of the mint may be a problem with the watering method, generally when watering the mint, you need to follow the principle of dry watering, do not water the potting soil if it is not dry, and wait for the soil to dry out at one time. When watering, it is best to use rice water, which can provide a certain amount of camp material for mint, and it can also be watered with ordinary water, but it is necessary to be careful not to water directly with tap water, and you need to dry the tap water in the sun for a period of time before using it.

Breathable and light-permeable. Peppermint prefers light, if the light is insufficient, it is easy to cause the leaves to turn yellow and black, so it is best to put it in a sunny place when breeding, if there is no sunny corner in indoor farming, you need to put the potted plant in a sunny place every two or three days to dry for a day or two, and so repeatedly, but it should be noted that in summer to avoid sun exposure, you need to carry out appropriate shading treatment.

There can be many reasons why the edges of mint leaves turn black, and here are some possible causes and how to fix them::

1.Improper water management: Excessive humidity or too dryness can cause the edges of peppermint leaves to turn black. If the soil is too wet, stop watering and make sure the soil is slightly moist. If the soil is dry, it should be watered immediately, but not overwatered.

3. Processing.

The blackening of mint leaves is also very likely to be caused by **, generally mint will suffer from rust and spot blight, if it is a leaf blackening caused by disease, it should be carried out in time**.

1. Rust: Peppermint rust is a disease infected by fungi, which is generally easy to develop in the rainy season of spring and summer, and is also easy to cause this disease when it is too dry. At the onset of the disease, there will be some yellow powder on the back of the leaves, and black spores will be produced in the later stage, resulting in black leaves, and when the disease is severe, the diseased leaves will dry up and fall off or even the whole plant will die.

**Rust can be sprayed with disodium or Bordeaux solution.

2. Spot blight: mint spot blight is also a leaf disease caused by a fungus, which generally occurs in summer and autumn, and some dark green spots will appear on the leaves after the onset, and the spots will slowly expand and turn gray-brown in the later stage, resulting in black and wilted leaves, and in severe cases, it will cause large pieces of leaves to fall off. To prevent and control spot blight, the diseased leaves should be removed in time, and all the infected leaves should be cut off and incinerated to prevent the spread of the disease.

1.Lacking in light, peppermint is a long-day crop. In general, it is necessary to ensure that there is enough light, and if the environment is dark, the leaves of the plant will turn black.

This requires that it be placed in a sunny position so that it receives light throughout the day, and if the light is particularly strong, it can be properly shaded with a 30% shading net.

2.Overwatering.

Peppermint loves moisture, and adequate water is very beneficial for its growth. But if there is too much water and the environment is too wet, it may also affect the respiration of the roots, which in turn will cause the leaves to turn black. This requires enhanced air circulation and proper loosening of the soil to allow the moisture to evaporate as soon as possible.

When watering, you should also pay attention to controlling the amount of water, not too much, especially not to produce stagnant water.

3.Excessive fertilization.

Peppermint does not require much fertilizer, as long as sufficient basal fertilizer is applied at the time of planting, top dressing is rarely required in the later stage of growth. If it is applied too much, it is easy to cause fertilizer damage, burn the roots, and turn the leaves black. In case of such a problem, it is necessary to remove the pot in time, remove the plant from the pot, wash off the old soil at the root, check whether there is a problem with the root, cut off the place where it has rotted due to burns, spray a little carbendazim for disinfection, and prepare for replanting after air drying.

Summary. Hello dear, <>

1. Insufficient light: Peppermint is a long-day crop, and insufficient light during growth will make the leaves wilt and blacken. 2. Watering too much:

Too much humidity in the soil and air makes the plants prone to dark leaves. 3. Excessive fertilization: If you apply thick fertilizer to mint for a long time, the root system will rot.

4. Disease cause: black spots will grow on mint leaves after being infected with rust and spot blight.

What is the reason why mint leaves are black.

2. Ventilation and light.

Peppermint loves light. If the light is insufficient, it is easy to cause the leaves to turn yellow and black. Therefore, it is best to keep it in a sunny place when breeding.

If there is no sunny corner in the indoor cultivation, the potted plants should be placed in a sunny place for a day or two every two or three days. And so on and so forth. However, it should be noted that proper shading is required in summer to avoid sun exposure.

3. Deal with nuclear dust.

The darkening of the mint leaves is also most likely caused by the disease. Generally, mint will have rust and white leaf blight. If the leaves turn black and it is caused by disease, it should be treated promptly.

1.Rust: Mint rust is a disease that is infected by a fungus.

At the onset of the disease, some yellow powder will appear on the back of the leaves, and black spores will be produced in the later stage, causing the leaves to turn black. In severe cases, the diseased leaves will dry up or even die entirely.

Rust can be achieved by spraying bait sodium or Bordeaux liquid on infected plants**. 2.Spot blight:

Peppermint's spot blight is also a leaf disease caused by fungi that usually occurs in summer and autumn. After the onset of the disease, some dark green spots appear on the leaves. In the later stage, the spots will slowly expand and turn grayish-brown, causing the leaves to turn black, wilt, and in severe cases, a large number of leaves will fall off.

To prevent white leaf blight, the diseased leaves should be cleaned up in time, and all the infected leaves should be cut and burned to prevent the spread of the disease. At the same time, Bordeaux liquid or zebsen solution can be sprayed**.
