Care
Exposure and light
Plant your Epacris impressa in a sunny or semi-shaded position to ensure abundant flowering. A well-exposed location promotes good air circulation and reduces the risk of fungal diseases. Avoid deep shade, which would limit flower formation.
Watering
Keep the substrate moist but never waterlogged, as the roots don't tolerate stagnant excess moisture. Water regularly during the growing and flowering period, then reduce slightly in summer. In a Mediterranean climate, regular watering is essential during dry months.
Soil preparation
Amend with white peat or heather compost to ensure soil acidity. Ensure excellent drainage by adding coarse sand or perlite. Avoid chalky or overly rich soils, which are unsuitable for this species.
Fertilization
Apply a low-nitrogen fertilizer, specialized for acid-loving plants (ericaceous plant fertilizer type), in late winter or early spring. One application per year is plenty. Poor soils are naturally better tolerated than overfeeding.
Pruning and maintenance
Prune lightly after flowering to maintain a compact shape and encourage branching. Remove spent flowers and any dead or diseased branches. Avoid severe pruning, which would slow recovery.
Pests and diseases
Watch for root rot if moisture is excessive. Aphids and spider mites may occasionally affect foliage in hot, dry climates. Encourage good ventilation and regular hygiene to prevent fungal problems.
Did you know?
Epacris impressa is emblematic of Australia's New South Wales and features on the state's flag and seal. It has fascinated European botanists since the nineteenth century with its spectacular winter flowering abundance, offering a symphony of scarlet reds and vibrant pinks in the midst of the Southern Hemisphere winter—a boon for gardeners seeking color during the dark months.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
