Peppermint thrives in consistently moist soil. Water regularly, especially during dry spells, ensuring the soil doesn't completely dry out.

Aim for deep watering to encourage robust root development, but avoid waterlogged conditions which can lead to root rot. Check soil moisture by touching the surface.

Regular pruning encourages bushier growth and prevents flowering, which can reduce leaf production and flavor intensity. Pinch back stem tips often.

In late fall or early spring, cut back the entire plant by about a third to remove dead or weak stems and stimulate new growth.

Peppermint is easily propagated from stem cuttings or by dividing root clumps. Take 4-6 inch cuttings in spring or summer, remove lower leaves, and place them in water or moist potting mix until roots form.

Divisions can be replanted directly into the garden or pots.

Peppermint can become quite vigorous and may need repotting annually or every other year. Repot when the plant outgrows its container, typically in spring.

Choose a pot that is slightly larger than the current one, and use a well-draining potting mix. Ensure good air circulation around the roots.
