Farming Notice

soil aspect

Mentha cultivation should be selected loose soil, good drainage fertile sandy soil.

in temperature

The cultivation temperature should be kept at 20-30℃, and mint has strong cold resistance and can withstand low temperatures of-15℃.

lighting aspect

Peppermint is naturally fond of sunshine, so sufficient light should be ensured, which can effectively ensure the normal flowering of peppermint and promote the accumulation of peppermint oil and menthol.

moisture aspect

Cultivation of mint requires more water, usually to keep the pot soil wet, especially in the early and middle stages of growth, especially in the flowering period can be appropriately reduced water supply.

planting aspect

When selecting branches, white thick rhizomes should be dug for planting, pruned into roots about 8 cm long and buried in the pot soil. After about 20 days, new branches can be produced. After cutting the tender stems, they can be cut in May and June.

How to water mint?

Mint likes water very much. It can be planted on the balcony in the open air and watered every day. In fact, young mint is not afraid of drought and flood, and has good growth ability and adaptability. Sufficient water supply can ensure the freshness of new leaves. The aging of root system and the elongation of stem affected the water supply of leaves. It can be used with watering to ensure water supply. Water directly above the plant with a watering can watering can. No roots, no pots. Different varieties have differences in water requirements, more dense leaves, more water requirements; less sparse leaves, less water requirements.

Mint pruning method

The pruning frequency of mint is best set once a week when the plant is growing vigorously, and weak branches, dead branches and twigs should be cut off.

After pruning, spray a new lipid membrane to effectively disinfect, and then place it in a sunny place to help further heal the tissue at the cut, thus promoting the germination of new branches.

Cause analysis and treatment of yellow mint leaves

1. Environmental mutation leads to yellow leaves of mint leaves: 1. Yellowing of leaves caused by excessive watering, usually watering is not easy to be too wet, too wet soil is easy to accumulate water to produce root rot and yellow leaves. 2. The soil plate is hard and impermeable, resulting in that the water after irrigation cannot penetrate into the soil layer, resulting in that most of the roots cannot absorb water and nutrients, resulting in the symptoms of yellow leaf drooping due to leaf water loss and nutrient loss.

Solution: It is best to keep the soil dry and water it, so that it is not dry and not watered, so that it is not easy for the growth of the root system to yellow the leaves. The best way is to loosen the soil properly, which is conducive to soil porosity and drainage, and is conducive to root growth.

2, too much watering leads to mint leaves yellow (water yellow): when watering wrinkled mint leaves, pay attention to the soil surface is not dry, do not water, dry water is poured through, the water used can be clear water, preferably the rice washing water at home, both nutrition and water conservation.

Solution: yellow leaves can be removed, pay attention not to pour too much water, mint vitality is very strong. Even if the leaves and stems are all wilted after a while, don't think it's dead, just cut off the wilted parts and wait for new buds to sprout. Don't throw them!

3, long-term water shortage causes mint leaves yellow (drought yellow): withered, zoom, leaves also become castrated.

Solution: mint is a very good plant, usually planted because of lack of water, so that the plant died, but if there is white matter on your plant, it may also be caused by pests, indoor balcony if there is no window open, poor ventilation, pests and diseases more likely to occur. The next time it happens again, it is recommended to trim the stem to 1/2 of the original, and spray some insect repellent, such as neem oil, lavender essence, usually will grow healthy new branches. With good moisture and pest control, plus good light and ventilation, mint can grow well.

4. Dry air causes yellow mint leaves: the tip of the leaf is dry or the leaf edge is scorched.

Solution: Attention should be paid to water spraying, plastic film cover, etc. to increase air humidity

5, insufficient sunlight causes mint leaves yellow (lack of light yellow): long-term too dark is easy to cause symptoms of long yellow leaves.

Solution: It is best to put it indoors in a sunny and ventilated place to reduce the problem of yellow leaves due to photosynthesis. It is better to remove it outdoors for 1-2 hours in the morning and evening sun.

6, the temperature is too high to cause mint leaves yellow: winter room temperature is too low, for sexual high temperature flowers are often vulnerable to cold damage, resulting in yellow leaves, serious yellow and death.

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

7, the temperature is too low to cause mint leaves yellow: if the room temperature is too high, the plant transpiration is too strong, the root water nutrient supply is 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 yellowing of leaves (fat yellow): new leaves are plump and uneven, and old leaves are dry and yellow.

Solution: should immediately stop fertilization, increase the amount of watering, so that fertilizer from the bottom of the drain hole out, or immediately pour the pot, water washing soil lumps and then re-planted into the pot.

9, rotten roots lead to mint leaves yellow leaves: leaves appear longitudinal wrinkle and deformity.

Solution: Find the root rot and cut it off at the base with scissors.

10. Pests and diseases lead to yellow leaves of mint leaves: leaf spot disease caused by fungi and other pathogens, easy to cause local necrosis of leaves, yellow spots or patches, serious whole leaves yellow and fall off, yellow and green mosaic mottled leaves after infection by mosaic virus; suffered from scale insects, red spiders, etc., leaves will also become local yellow and withered, even whole leaves yellow and fall off.

Solution: All should be timely spraying control.
