How to care for Prostanthera cuneata:
Plant Prostanthera in a warm, protected place, water sparingly once established, and keep it on the dry side through winter. After flowering, give it a light trim to keep its shape, then mulch with 5-7cm (2-3in) of compost to improve soil structure and hold moisture. In colder areas it’s best grown in a so it can be moved to shelter before temperatures fall close to freezing.
