More details about Spearmint

Mentha spicata. Compared to peppermint, spearmint has a less aggressive flavour that has fruity undertones. This mint is easy to grow, and it's fast, too. In boggy settings it can spread by underground rhizome, but this is easy to control by growing it in containers. The leaves dry well and even fresh they make a nice tea — an even nicer mojito. Sow the seeds indoors a month or two before the last frost date, and transplant out when night time temperatures are steadily above 10°C (50°F). Ninety days later, expect white to lilac flowers that are both edible and highly attractive to bees. This mint is perennial and hardy to Zone 4.

Timing

Timing
Sow indoors 8-10 weeks before last frost, or direct sow in late spring. Seeds should sprout in 10-16 days. Bottom heat will speed germination.

Starting

Starting
Sow seeds no more than 5mm (¼”) deep in moist soil. Space plants 45-60cm (18-24″) apart.

Growing

Growing
Mint spreads in the garden with gusto via a vigorous root system, so it may be preferable to confine it to planters on the balcony or in a raised bed. Prune plants back hard in early summer to promote good top growth. Bring some inside to grow in a small container over winter to grow on a brightly lit windowsill.

Harvest

Harvest
Clip leaves or branches as needed throughout the year. Mint is so hardy and tough that it will grow right back. Dry the leaves and flowers for peppermint tea, or use them fresh. The flowers are edible and bring distinctive character to salads and sweets.

Companion Planting

Companion Planting
Mint attracts earthworms, hoverflies and predatory wasps, and repels cabbage moths, aphids, and flea beetles. Mint can spread aggressively, so it may be better to use cut mint as a mulch around Brassicas, or to restrain it in containers around the vegetable garden. Avoid planting near parsley.
