1、 Seedling pruning

Peppermint needs a pruning at the seedling stage. Generally, when it grows to 8-10cm, its terminal bud needs to be cut off. By removing the top edge of the plant and promoting the growth of lateral branches, it can make it look more lush and avoid the risk of overgrowth and lodging. After the branch grows to a certain extent, its terminal bud can also be cut off to promote the re branching

2、 Post flower pruning

The flowering period of peppermint is in summer. Generally, it also needs to be trimmed after flowering. Because flowering will continue to consume nutrients, it is necessary to cut off the residual flowers in time after flowering, and cut off the relatively weak branches at the same time, which can reduce the loss of nutrients and make it grow stronger. In addition, the pruning time should be early. If it is late, it will affect its smell

3、 Pruning during growth

Peppermint needs to be re cut during the growth period, and the branches with signs of diseases and pests will be cut off to avoid further deterioration. At the same time, some thick branches should also be thinned properly, which can increase the internal ventilation and light transmission, and also provide space for the growth of new branches

4、 Dormancy pruning

Winter is the dormancy period of mint. At this time, the pruning range should not be too large. The dead branches and rotten leaves can be cut off. For some branches with poor growth, they can also be reduced by about 3-5cm, so as to make its nutrient supply more concentrated
