Mentha spp.
Mint is a hardy, vigorous herb that grows well in the ground or in pots across the UK. It spreads quickly, so containers or a contained bed are usually the easiest way to keep it under control.
Step-by-step instructions for growing Mint

Plant mint in a contained bed or sunk pot if you want it in the soil. It spreads by runners, so containment is the main job.
Sow seed thinly on the surface of seed compost around 29th January - 29th March and barely cover it. Keep the compost evenly moist while the seedlings emerge.
Prick seedlings out into individual pots from 20th March once they are easy to handle. Grow them on until roots fill the pot and the plants are sturdy.
From 1st March, acclimatise plants outside over about 10 days before planting them out. Keep them out of cold wind and bring them in if a late cold spell is forecast.
Set plants into prepared ground from 17th April, spacing them so air can move around the clump. Water in thoroughly straight after planting and keep them watered until they are properly rooted.
From 24th April, check runners and cut them back before they root where you do not want them. In the ground, this is the main job that keeps mint tidy and stops it taking over.
Begin picking from 19th June once the plants have bulked up. Pinch out the tips often from 19th June to 26th October and harvest regularly to keep fresh growth coming.

Companion planting can deter pests, improve pollination, and make better use of space. Some plants confuse pests or attract beneficial insects; others improve soil or offer shade to neighbours that need it.
