Common Mint Varieties
Popular cultivars to look for at your local nursery or seed supplier.
Spearmint
The classic garden mint with sweet, mild flavor; used in drinks, desserts, and cooking.
Peppermint
High-menthol variety with intense cooling sensation; great for teas and herbal remedies.
Chocolate Mint
A subtle chocolate-mint scent makes this a favorite for dessert teas and garnishes.
Apple Mint
Fuzzy-leaved mint with mild, fruity flavor; more drought-tolerant than spearmint.
Lemon Balm
Lemon-scented member of the mint family; used in teas, salads, and as a bee attractant.
Common Mint Problems
What to watch for — and how to fix it before it spreads.
Pests
Tiny beetles create small round holes in leaves; rarely serious.
Tolerate light damage; heavy infestations can be treated with spinosad.
Stippled, pale leaves with fine webbing in hot, dry conditions.
Increase moisture around plants; spray with neem oil or insecticidal soap.
Cluster on new growth; exude honeydew that attracts sooty mold.
Blast with water; apply insecticidal soap; mint's strong scent naturally deters many pests.
Diseases
Powdery orange-brown pustules on leaf undersides; infected leaves drop prematurely.
Remove and destroy infected parts; improve airflow; avoid overhead watering; divide clumps.
White powdery coating on leaves; worse in shaded, humid conditions.
Plant in good airflow; avoid overcrowding; spray with potassium bicarbonate.
Yellowing and wilting of individual stems caused by a soil-borne fungus.
Divide and replant in fresh soil; avoid replanting mint in the same spot for 2–3 years.
Common Mistakes
Mint spreads aggressively via underground runners and will take over a garden bed.
Grow in a container or bury a pot to its rim in the ground to contain the roots.
Cutting stems too short stresses plants and slows regrowth.
Remove no more than 1/3 of the plant at a time; cut just above a leaf node.
🌾 Seed Saving Guide
🟡 ModerateWhen to Harvest Seed
Let flower spikes dry completely on the plant. Harvest before seeds shatter.
Processing
Strip dried spikes over a bowl, seeds fall easily. Dry extra 1–2 days before storing.
Seed Viability
Up to 2 years when stored cool, dark, and dry.
Pro Tip
Mints cross-pollinate freely — seeds won't grow true to the parent variety. Propagate by cuttings or division for exact flavor.
