Overwintering -
Calluna vulgaris will not likely overwinter in containers but can be planted in the garden.
Light -
If planting in the garden plant in full sun to part shade in an area that is somewhat sheltered to avoid wind damage.
Soil -
Calluna vulgaris requires a fairly acidic soil similar to that of Rhododendrons. Therefore alkaline soils should be amended with peat moss in order to bring down the pH in the soil to below 6. Plant in well-drained soil.
Fertilizer -
Calluna are not heavy feeders and require very little fertilizing. Some bone meal sprinkled on the soil surface could be beneficial and a light Rhododendron feed such as 6-12-12 could be used. In high heat and humidity Calluna can be affected by fungal disease, which manifests as browning on the tips.
Hardiness -
Calluna vulgaris are hardy to zones 4-6 surviving temperatures down to –20 degrees Celsius. In areas where snow cover is not plentiful enough to provide good insulation it is recommended that pine needle mulch or evergreen boughs be placed over the plants as protection from winter cold and wind.
Pruning -
Calluna should be pruned back in spring to just below the flowers to maintain a tidy plant as well as encourage vigorous new growth and flowers.
Size -
It will grow 1 to 2 feet tall and 1 to 2 feet in width.
