Peppermint thrives in consistently moist soil. Water regularly, especially during dry spells, ensuring the soil remains damp but not waterlogged. Overwatering can lead to root rot, while underwatering causes wilting.

Aim for about 2-3 cm of water per week, adjusting based on temperature and humidity. Container plants may need more frequent watering.

Regular pruning is crucial for maintaining a healthy and productive peppermint plant. Pinch back the growing tips frequently to encourage bushier growth and prevent the plant from becoming leggy.

After flowering, cut back stems by about one-third to stimulate new growth and a potential second harvest. For general harvesting, snip stems just above a leaf node.

Aggressive pruning also helps to manage its vigorous spreading habit.

Peppermint is easily propagated by stem cuttings, division, or runners. Take 10-15 cm stem cuttings, remove lower leaves, and place in water or moist potting mix.

For division, dig up a clump and separate the rhizomes with roots attached. Plant runners directly into new soil for rapid establishment.

Container-grown peppermint benefits from repotting every 1-2 years, ideally in spring. Choose a pot slightly larger than the previous one, ensuring good drainage. Refresh the soil with a fresh, well-draining potting mix.

This helps to invigorate the plant and prevent it from becoming root-bound, which can stunt growth and reduce vigor.
