When planting mint, keep the soil moist, water once every half month at seedling stage, apply a small amount of urea solution every month, combine fertilization with watering, grow in the middle or do irregular weeding treatment to avoid nutrient consumption and make mint grow more vigorously.
Mint likes to live in the sun. Adequate sunshine can make it flourish, and it is also conducive to the accumulation of substances in the body and improve its quality. If the weather continues to rain, it will affect its growth, with few ramets, small and thin leaves and poor quality, which will easily lead to longevity. Therefore, we should pay attention to control the planting density, avoid the branches and leaves blocking each other, reduce the ventilation and light transmission performance in the field, and make the illumination sufficient and uniform.
When planting in greenhouse, we should pay attention to the light in the greenhouse, especially when planting mint in spring and summer. In order to ensure the healthy growth of mint, we should use plant lights to fill the light. Due to the seasonal change of weak light and the change of weather, long-term cloudy weather will seriously affect the light in the shed, thus affecting the growth of mint. The plant fill light lamp is made according to the principle that plants use sunlight for photosynthesis. It can replace sunlight to supplement the light of mint and meet the demand of mint for light intensity and time. It can be planted in greenhouses, homes or flower shops.
But if it is potted, the cold tolerance will be much lower, but it will not freeze to death at the temperature of MINUS 10 degrees. So for potted plants, if possible, dig a small hole in a sunny place outdoors, bury the flowerpot underground and cover it with a thin layer of soil or weeds.
