Like all erica species Erica haematocodon may be grown from seed or cuttings, however, cuttings are easier and faster to grow and produce plants that are far more robust. Plants grown from cuttings can also be transplanted within six months, as opposed to a year for seed-grown plants, and they will flower a year earlier (Schumann et al. 1992). Considering the rarity of this species, however, seeds are likely to be your only option for propagation--regard it as a challenge!

Seed can be purchased from a number of sources, one of which is Kirstenbosch National Botanical Garden. If you already have a plant, you should harvest seed just as the flowers start to fall naturally. The old flowers should be dried and then rubbed through a sieve. Sow seed between March and May in a seed tray not less than 100 mm deep. Seed may be soaked in a commercial smoke seed primer for 24 hours before sowing and then dried off. The seed tray, evenly filled with the well-drained acidic medium, should be well watered with a fine rose prior to sowing. Sow seed evenly and cover with a fine layer of the sieved growing medium. Water gently with a fine rose and keep out of direct sunlight and rain in an area with good air circulation. Germination occurs within 1-2 months. When the seedlings are about 10 mm tall place the tray under light shade conditions until October-December. When 20-50 mm tall, prick out and plant in a fynbos potting medium (seven parts sand and three parts sifted humus). Place in light shade and water well. Once established, shading is not required.

Take 40-50 mm cuttings from semi-hard wood two months after flowering from healthy mature plants. Heel and stem cuttings work best. Remove the leaves from the lower 1/3 of the cutting, dip into a rooting hormone and place into a tray filled with 50% peat, or crushed pine bark, and 50% polystyrene. Bottom heating between 22-24°C is applied, and once cuttings are rooted they are potted up into ½ liter plastic bags. Young cuttings must be watered well and kept under shade for a month, after which they are placed into full sun. After 3-4 months plant out.

Soil is a sensitive issue. The potting medium should be well drained and acidic, containing no manure, and have low levels of phosphate. A well-drained sandy loam with a pH between 5 and 5.5, containing about 50% humus is ideal (Brown et al. 2006). Ericas grow better when planted close together with other fynbos plants to form dense stands that cover the ground. They grow particularly well in rockeries or sloping ground but level areas will work as well. Before planting dig in some well rotted pine bark.
