Erica blandfordia can be successfully grown in garden plant beds provided that it is positioned in an area that receives full sun and good soil drainage is maintained. The soil pH should be in the acidic range (4 to 5.5). The plants should not be planted too densely, good air circulation is important. This plant has no taproot, but has a a delicate, hair-like root system and care must be taken not to damage the roots when cultivating these plants. Prune the plant after flowering to encourage new growth and to clean up the plant by removing dead or damaged wood. Organic fertilisers may be added in low concentrations. Adding a layer of mulch, consisting of wood chips, is ideal to assist in controlling weeds and to keep the soil moist.

Erica blandfordia can be successfully propagated by taking semi-hardwood cuttings ±40-50 mm long, ideally two months after flowering, as a general rule for propagating ericas. Use heel cuttings or nodal cutting; at Kirstenbosch we find that heel cuttings deliver better results. Select healthy and disease-free plants. Different soil media are available, however we recommend a rooting medium of fine-milled bark mixed with perlite balls at a 50:50 ratio, which has proved to result in good rooting. The rooting media should be well-drained and heated propagation benches should be kept at a constant temperature of 24°C.

Transplant the rooted cuttings into small pots using a soil mix that is a ratio of 7 parts milled bark and 3 parts sand, which is an ideal medium for further development of the young cuttings. Cuttings will develop into young plants much quicker than seed-grown plants. Harden the cuttings off for a month before placing in open environmental conditions. The cuttings will be ready for planting after about 3 months.

Seeds need to be treated with smoke first, such as soaking them in a fynbos smoke extract, and sown in autumn. Seed germination varies from one to two months. Feed the rooted cuttings with liquid organic fertiliser every 14 days. As a general guideline for sowing erica seed, use equal parts of river sand and sifted composted bark in 100 mm deep seed trays. Do not sow seeds too densely, mixing the seeds with fine river sand and spreading this over the surface of the tray will ensure a more even spread of the seeds. Apply water lightly and shelter the seeds from direct sunlight.

Young plants are often plagued by mealybug, control them by applying an organic contact pesticide or a systemic control that can be added to the soil medium. Prevent root disease by ensuring that the potting medium has sufficient drainage, the soil of garden plant beds also requires good drainage.
