— Soak the roots in water for 3-6 hours prior to planting out.

— Plant directly into a clear space in borders in spring. To help them establish quicker, you can pot them up into temporary pots first to plant out later in the season.

— Plant the roots so that they are fully submerged with the buds or crown just below the surface or any top growth exposed.

— Choose a sunny position with free-draining soil. If you are planting in containers, you can use multipurpose or soil-based compost.

— Space the plants 15-20cm apart
