Care guide

Plant in partial shade or sun in moist, fertile soil. Ideally plant in a pot or contain the roots with a buried barrier to prevent spreading. Water generously, especially in summer. Feed monthly with liquid fertiliser.

Pruning tips

Harvest the tips regularly to keep the plant compact and productive. Cut off flower spikes as soon as they appear to encourage leaf production. In autumn, cut everything back and cover with compost.
