How to Grow Mint
Mentha
Mint is a vigorous, hardy perennial that prospers in moist, fertile, free-draining soil with sun or partial shade. It spreads by underground stems—contain in pots or dedicate a patch. Water regularly, especially in containers, and shear plants mid-season to refresh tender shoots. Harvest tips frequently; flavour is best on young growth. Divide congested clumps every 2–3 years to maintain vigor. Watch for rust; remove affected leaves and encourage airflow.

☀️ Light
Sun or partial shade; best flavour in sun
Grows well in full sun or partial shade. Flavour is strongest in sun, but mint tolerates more shade than most herbs.
💧 Watering
Keep consistently moist; don't let dry out
Keep soil consistently moist, especially for container-grown plants. Mint is one of the few herbs that prefers damp conditions.
🌱 Fertilizing
Light spring feed; avoid over-fertilising
A light feed in spring is sufficient. Too much fertility produces lush but less flavourful growth. Refresh container compost annually.
✂️ Pruning
Hard cut after flowering; ground level in autumn
Cut back hard after flowering to encourage a fresh flush of tender leaves. Cut to ground level in autumn when foliage dies back.
🍎 Harvesting
Pick regularly before flowering for best flavour
Pick leaves regularly to encourage bushy growth. Best flavour before flowering. Cut whole stems rather than individual leaves.
Growing Tips
Grow in bottomless pots
Sink large pots into beds to keep roots corralled while allowing moisture access.
Mid-season reset
Cut back hard after flowering, water well, and feed lightly for fresh regrowth.
Divide to revive
Lift and split clumps in spring to renew plants and expand your patch.
Pests & Diseases
Pest Aphids
Identification: Clusters of green or black aphids on young shoots; sticky honeydew; distorted and curled leaves
- Blast off with a strong jet of water
- Encourage ladybirds and lacewings as natural predators
- Avoid chemical sprays on culinary herbs; use fatty acid-based spray only if essential
Pest Whitefly
Identification: Tiny white-winged insects fly up when foliage is disturbed; found on leaf undersides
- Use yellow sticky traps to monitor and reduce numbers
- Introduce Encarsia formosa parasitic wasp in greenhouses
- Spray with fatty acid-based insecticide; avoid systemic chemicals on edible herbs
Disease Mint Rust Puccinia menthae
Symptoms: Small orange-brown pustules on stems and leaf undersides in spring; swollen, distorted shoots with pale orange spores; leaves yellow and drop
Treatment: Cut all growth to ground level and burn or bin it; do not compost; water the crown with boiling water to kill overwintering spores
Prevention: Buy certified disease-free plants; avoid overhead watering; ensure good air circulation; replace stock every few years
Disease Powdery Mildew Erysiphe spp.
Symptoms: White powdery coating on leaves, especially in late summer; leaves may yellow and become unpalatable
Treatment: Cut back affected growth hard; fresh regrowth is usually clean
Prevention: Ensure good air circulation; avoid overcrowding; water at the base rather than overhead
