Erica vernicosa grows well in soil with a pH ranging from 5.5-6.7 and prefers a sunny position away from direct wind. Regular pruning and feeding with an organic liquid fertilizer will encourage new growth and flowering.

Take cuttings 2 months after flowering, take heel or nodal cuttings from semi-hard wood. Trials have shown that cuttings made ± 40–50 mm in size root best when a rooting hormone for semi hard wood cuttings is applied. Use a rooting medium made up of 50% fine-milled bark and 50% polystyrene chips for the cuttings. Ideal conditions to propagate this plant successfully requires a constant bottom heat of 24°C and regular misting of the cuttings at least every 10 minutes. Plant the cuttings into small pots when rooted, in a soil mixture of 8 parts bark and 3 parts sand, water well. Apply an organic liquid fertiliser every 2 weeks. It will take ± 3 months for the cuttings to be ready for planting out.

Sow seeds in the cooler months of the year, around April and May when the temperature naturally starts to drop. Use seed trays about a 100 mm deep, filled with equal parts of river sand and sifted composted bark. Place a thin layer of chipped stones in the bottom of the seed tray to allow for good drainage. Mix the small seeds with fine river sand to allow for an even spread of the seeds. Place the trays in a warm and sheltered spot and keep the medium moist by watering with a fine hose. The seeds will start to germinate within ± 2 months. The seedlings can be successfully planted out once they reach 10 mm height.

Ericas are not much prone to attacks by pests, therefore preventative measures such as not to sow seeds too dense and to maintain good air circulation can prevent fungal attacks. Thrips and cutworm can be easily controlled by applying an appropriate product and by following application directions carefully.
