How to harvest Japanese Mint

Fresh Apple mint leaves can be harvested as needed as soon as the plant reaches 10cm in height. To dry, cut stalks just before blooming.

How to propagate Japanese Mint


Sow in Spring, depth 6mm; 15 cm apart directly in the ground. Most mints have fairly aggressive roots, so its best to grow them in containers buried in the soil.


Take 5 to 10 cm stem cuttings and place them in moist and well-draining soil in semi-sun. It should root in under two weeks. Transplant into a larger pot a few weeks after the cuttings have rooted.​


Mentha plants are prone to hybridization, therefore,​ division is a good method if you want to preserve a particular aroma.
