How to harvest Pineapple Mint
Spring - Autumn. Essential oils in the leaves are at their peak just before flowering. This would be the ideal time for harvesting leaves to be dried. For fresh use, pick the youngest leaves before the plant flowers.
How to propagate Pineapple Mint
Divides easily by simply taking a stem with a piece of root and transplanting. Do not plant with other mints, since they cross-breed easily and will lose their distinctive aromas.
The horizontal growth of its underground rhizomes lend it to aggressive spreading. When pulled out, small pieces are usually left behind and new plants easily grow from them.
Not the most preferred method, because mint seeds are very variable, and some varieties are sterile. Seeds should be planted in spring at 6mm depth and thinned out later in the year.
Take cuttings of rooted stems and plant them horizontally in the soil. Also roots easily grow from stem or root cuttings placed in water. Root tip cuttings are best taken in spring.
