Mint has strong adaptability and is not picky about the surrounding growth environment, so it can be kept in water, and the maintenance and management are very simple, which also reduces the possibility of insects. In addition, mint likes plenty of water, so soil culture requires frequent watering, while hydroponics can provide enough water. However, hydroponics also has disadvantages, that is, it is easy to die. If water is not changed for a long time, the roots of plants will rot and die, and plants will die.

Second, the method of water conservation

1. Cut a branch from the top of a robust plant, which is about 4-5 cm long, to avoid pests and weak branches. Treat the leaves under the branches to prevent them from rotting in water.

2. Prepare transparent glass containers, which need to be cleaned before use and then disinfected. Pour clean water into the glass container, which needs to be prepared in advance, take it out of the water pipe and put it aside to volatilize chlorine.

3. Insert the treated branches into the water and put them in a place with good sunshine. At first, change the water every 1-2 times and add a little nutrient solution appropriately. After a few days, fine roots will grow, so it is not necessary to change the water so frequently, and it is ok to change the water once a week instead.
