Planting instructions

Choose a container, with drainage holes at least twice the size of the one the plant is currently growing in. Place stones, broken up flowerpots or polystyrene in a thin layer over the holes to help with drainage. Place a layer of multi-purpose compost on top. Remove the pot and position the plant so the top of the rootball sits 2.5cm below the rim of the pot. Fill around the rootball with compost, firming as you go. Water in well and keep well watered especially through dry spells.

Planting site Cottage garden, Informal garden, City garden, Courtyard garden, Flower border and beds
