Choose a mint variety suitable for containers (spearmint, peppermint, chocolate mint)
Use a pot with drainage holes and a minimum size of 8–12 inches (larger is better)
Fill with well-draining potting mix (container potting soil or potting mix amended with perlite)
Plant mint so the top of the root ball sits at the same level as the soil surface
Place the pot in bright light near a window (6+ hours of direct or strong indirect light)
Provide 10–14 hours of light using a grow light if natural light is limited
Water when the top 1 inch of soil feels dry
Water thoroughly until excess drains out, then empty the saucer
Keep soil consistently moist but not soggy
Maintain indoor temperatures around 65–75°F (18–24°C)
Avoid cold drafts and heat vents that dry the plant
Fertilize lightly every 4–6 weeks with a balanced liquid fertilizer at half strength
Pinch or cut stems regularly to encourage bushy growth
Harvest by snipping above a leaf node or just above a pair of leaves
Remove any yellowing or dead leaves promptly
Rotate the pot weekly for even growth toward the light
Keep mint isolated from other plants in the same pot; use separate containers or a root barrier if sharing space
Watch for pests (aphids, spider mites, whiteflies) and treat early with insecticidal soap if needed
Increase humidity if needed (especially in dry indoor air) without misting leaves excessively
Repot every 1–2 years or when roots fill the container
Propagate from cuttings or division in spring or early summer
Root cuttings in water or directly in moist potting mix until established
For division, separate root clumps and replant into fresh, moist soil
