Mentha ×piperita requires watering every 2–4 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Well-draining, fertile soil with a neutral pH. Good drainage is essential for Peppermint to prevent waterlogging, which leads to root rot and fungal issues.

Feed Peppermint every month during the growing season (spring and summer) with a balanced fertilizer diluted to the strength on the label.

Pause feeding in autumn and winter, when growth slows, and never fertilize dry soil — water first.
