Lack of moisture can be quickly recognized by hanging leaves, which then straighten up just as quickly after watering.

The leaves and shoots of peppermint can be harvested throughout the growing season. It is best to only cut as much as you need. If you want to stock up for winter, you can also dry the peppermint. But then you need to know that some of the aroma will be lost.
In order to optimally maintain the healthy growth of peppermint, you have to cut back the plant strongly at least once, but better twice a year. The best times for this are early spring and August immediately after flowering. In addition to pruning, puncture all the side runners of the plant, which is more likely to spread, with a spade.
Peppermint is one of the hardy mint, which usually survive even strong frost without damage. If you want to be on the safe side in the event of extreme freezing temperatures, cover the plants with a layer of brushwood in late autumn. The branches of conifers such as fir or spruce are very suitable for this.

Immediately cut a diseased peppermint back to the ground and water it with a field horsetail broth for several days. If the new shoots and leaves continue to show symptoms, you must remove the plant and its roots to protect neighboring plants.
