| Right about now is a good time to harvest. The berries should be plump and firm. Plant the seeds (the entire little "berry") immediately. You can do so just by poking the berries into the soil adjacent to the original clump to increase its size or in a greenhouse setting. This is not a fast plant to produce, hence its expensive nature - you'll need patience. Commercial propagation is typically by division of the spreading rhizomes |
