  • Easy to grow. Grow in trays and plant out or start from cuttings. Sow seed at a depth approximately three times the diameter of the seed. Best planted at soil temperatures between 70°F and 75°F. (Show °C/cm)
  • Space plants: 12 inches apart
  • Harvest in 8-12 weeks. Cut leaves from top with scissors.
  • Compatible with (can grow beside): Cabbages, Tomatoes
  • Mint leaf

Although mint can be grown from seeds, cuttings are a faster, more reliable option.
Cuttings can be planted directly when danger of frost is past. Mint can be grown in pots outdoors or indoors

Mint prefers damp, partly shaded areas and once established will grow for many years. Mint dies down in Winter and sends up new shoots in Spring.

Mint is a rampant grower and will take over a garden bed if not restrained.

One way to contain mint is to use an old bottomless bucket pushed into the ground. The mint won't be able to put its roots out sideways, so will take longer to spread. If grown in a pot, mint needs to be watered regularly to keep it healthy.

Culinary hints - cooking and eating Mint

Mint adds a fresh flavour if chopped and sprinkled over salads. And is traditionally used mixed with vinegar and sugar to make mint sauce for lamb.

My mint is very yellow on the lower leaves. How do I make it more healthy. Is there a tip to adding something to the soil? Or do I just need to pinch all the tips off?

Pinch all the yellow leaves off and give it a shot of fertiliser. Mix some in a bucket of water and apply -1-2-3 teaspoons.

This is my first mint plant ever, we planted it outdoors in a raised bed... Winter is coming, do I need to protect it by covering it, or can I just trim it and leave it alone.

I live in Perth Western australia and would like to grow different and interesting varieties of mint. For example: Chocolate mint, Apple Mint Spearmint Vietnamese Mint any suggestions where I can find these seedlings. or do I have to start them from seed? Thank you, Sophie

Hi Sophie, You could see whether any online seedling / seed companies in Australia ship to your area. This seems to be the best bet for finding interesting varieties. I was able to order quite a few varieties of mint from Mudbrick Cottage Herb Farm (www.herbcottage.com.au), however unfortunately they are unable to post plants to WA due to quarantine restrictions (I live in Victoria). My order included pineapple mint and variegated apple mint. I just planted them up today, and they smell so good! Early spring is possibly the best time for sourcing mint seedlings, as they die off over winter and re-sprout in spring (although perhaps in WA they re-sprout earlier). All the best with your search!

I think you would have a lot of trouble trying to find seedlings for different mint in one place. Probably have to look at seed selling companies, Boondie Seeds- New Life Seeds - The Seed Collection company and others if you look.

Cut garlic cloves, mix it with warm water. Put in a sprayer. Stinks but it’s natural. Caterpillars gone!
