Erica plukenetii, like many other ericas, is very easy to garden with, provided you give it the right conditions. It needs a sunny position with good air circulation and well-drained (sandy), acidic (pH 5 to 6.5) soils. Like most ericas it grows very well in rockeries or sloping ground, although the plants do not mind growing on level sites as long as they are well-drained. The ideal time to plant ericas in the Cape is in autumn or early winter. The planting hole should be large enough to accommodate the size of the container. Remove the plastic bag or pot carefully and take care to keep the root ball intact. Fill in around the plant, firm the soil down lightly and then water well. Place a thick layer (25-50 mm) of mulch around the plant, mulching keeps the soil surface around the plant cool and suppresses weed growth. Do not add manure or strong fertilizer.

When growing ericas in pots it is important to plant them in the correct soil. The growing medium should be well-drained and acidic with no manure and with low levels of phosphate. A well-drained, sandy loam with a pH of between 5 and 6.5, containing 50% humus is recommended.

Erica plukenetii can be propagated by seed or cuttings. Seed should be sown in autumn and treatment with smoke will improve germination, resulting in a higher number of seedlings. Ericas are rooted using semi-hardwood tip or heel cuttings in late summer to autumn or in spring. Treat them with a rooting hormone for semi- hardwood cuttings and place in a well-aerated medium under mist on heated benches.
