The cultivation methods of hydroponic mint are as follows:

1. Change water regularly

The water of hydroponic mint should be changed regularly to ensure the water quality is clean. Under normal circumstances, it is necessary to change water once every 7-1 days. It is best to use clean well water or river water. If tap water is used, it must be exposed in advance before use, otherwise the chlorine inside is too heavy, which will affect the growth. In addition, the container should be cleaned when changing water to ensure that the container is clean.

Second, applying fertilizer

There are relatively few nutrients in the water. In order to promote the vigorous growth of mint, it is necessary to apply fertilizer regularly. Liquid fertilizer or special nutrient solution can be added to the water, and a small amount can be added every time the water is changed to ensure sufficient nutrition in the water, so that mint can grow well. In addition, foliar fertilizer should be sprayed on the leaves in the peak season, so that the leaf color will be greener.

3. Proper exposure to light

Although mint has certain shade tolerance, it needs proper sunshine during curing, and sufficient sunshine can promote it to accumulate more nutrients and grow vigorously. Note that only scattered light can be accepted, just put it in the low light indoor. Direct light and strong light must be blocked in time, otherwise it is easy to get sunburned and yellow leaves are easy to appear.

Fourth, the temperature is suitable

Mint likes warm environment, and its cold tolerance is relatively poor. It is best to provide an environment between 2℃ and 25℃ during hydroponic maintenance, in which it can flourish. If the high temperature exceeds 3℃ in summer, it is necessary to strengthen ventilation and spray water frequently to cool down. If the temperature is lower than 1℃ in winter, it is necessary to move indoors and control the temperature above 1℃, otherwise there is a danger of frostbite.

V. Precautions

Observe the growth of mint during hydroponics, and prune it in time if there are rotten or dead roots to avoid polluting the water quality. Check the root system every time you change the water.
