1. Time things correctly
It's important to time things right and plant your mint seeds indoors in early spring.
'The idea is the get them started approximately 6-8 weeks before the last frost date in your area,' explain Lucy and Kate.
2. Sow the seeds
'Sow the seeds thinly on the surface of moistened peat free compost, gently pressing them into the soil without covering them completely, as mint seeds require light to germinate,' advise Lucy and Kate.
'Maintain consistent moisture levels to help germination along, and be sure to place the seed tray in a warm location with indirect sunlight, like a windowsill.'
2. Give them space
After a couple of weeks, you should notice that your seeds are starting to sprout.
'As the seedlings emerge and develop their first set of true leaves pop them in individual pots to allow them room to grow,' say Lucy and Kate.
3. Get them outdoors
It doesn't matter if you have a a small vegetable garden or a pot on a patio/balcony, it's important to get your mint seeds outdoors once they've germinated.
'Once the danger of frost has passed and the seedlings have grown to a height of , they can be transplanted outdoors into their permanent location,' advise Lucy and Kate.
'Choose a sunny to partially shaded spot in your garden or container with fertile, well-draining soil. Space the transplants according to their mature size, as mint plants can spread vigorously.'
4. Show them some love
It's a vital step in anyone's Grow Your Own adventure: learning to care for your edimentals as they long to be cared for! Thankfully, mint is relatively low maintenance, making them an ideal project for even the greenest of gardeners.
'Keep the soil consistently moist but not waterlogged, as mint has shallow roots and can wilt quickly in dry conditions,' say Lucy and Kate.
'Mulching around the plants helps retain moisture and suppresses weed growth, and be sure to pinch back the growing tips regularly to encourage bushier growth and prevent the plant from flowering, which can make the leaves bitter.'
5. And don't forget to harvest
'Once your mint plants have become established, you can start harvesting leaves for culinary or medicinal purposes,' explain Lucy and Kate.
'Simply snip off individual stems or pinch off leaves as needed, avoiding stripping the plant entirely.'
Don't be afraid to get stuck in, as the duo adds that 'regular harvesting encourages new growth and keeps the plant productive throughout the growing season'.
