Erica ericoides will grow happily in a soil with good drainage and a pH around 5.5 to 6.7. Avoid areas in the garden where the plant will be shaded for most of the day, or where it will experience extreme heat in summer. When planting among other fynbos plants, avoid overcrowding the plants, because poor air circulation may create a micro climate that enables fungal growth. Weed lightly around plants to prevent damaging their delicate hair-like root system. Regular pruning after flowering and feeding is important to encourage new growth.

Take 40-50 mm cuttings from semi-hard wood, 2 months after flowering. Heel cuttings are ideal, however nodal cuttings can also deliver good results. Remove the lower third of the cutting’s leaves. Apply a rooting hormone for semi-hardwood to the cutting, this will speed up the root development. Place the cuttings in a rooting medium made up of 50% fine-milled bark and 50% polystyrene chips. Heel cuttings from thin, actively growing side shoots respond more positively when it comes to root development. The cuttings develop best when good air circulation is maintained. Good air circulation is important as it reduces fungal infections. A specialised facility, such as a propagation unit with heated benches and a misting system, is best to successfully propagate this plant by cuttings. Cuttings can be planted into small pots when rooted, in a soil mixture of 8 parts bark and 3 parts sand. Feed every 2 weeks with an organic liquid fertiliser.

Sow seeds in seed trays about a 100 mm deep, filled with equal parts of river sand and sifted, composted bark, in autumn. Wet the medium with fynbos smoke extract (obtained from burning fynbos plant material) and only use pure water after one day. The seeds are very small and need to be mixed with fine river sand prior to sowing, in order to obtain a more even spread of the seeds. Keep the medium moist by watering with a fine hose. Place the trays in a warm and sheltered spot to encourage the germination process. The seeds show signs of germination after 6–10 weeks. Seedlings can be planted out into small pots as soon as they are about 10 mm high. Thereafter, plant the plants in garden beds as soon as they are ± 100 mm tall.
