Erica glauca var. glauca is not regarded as the easiest of ericas to grow in the average Cape garden, but will survive in Cape Mediterranean conditions. The key to growing this species is very good drainage and not too much water. It should be planted in gardens where it is in full sunlight and well ventilated. This species performs best when planted in rockeries on sloping ground, terraces or embankments and with other fynbos plants. It prefers warm sunny positions. Companion plants may include other ericas, buchus, brunias and restios.

If these conditions cannot be provided, it grows well in medium-sized containers with the correct, well-drained growing medium. Fynbos planting medium is made up of a combination of equal parts composted pine bark or pine needles and river sand. A little (20%) loam may also be added. It is a woody species, so regular pruning is recommended to keep the plants well branched and compact. Plants that are pruned are more presentable, last longer and produce more flowers.

Erica plants are adapted to growing in nutrient poor soils and therefore require low nutrient levels. Ericas, nevertheless still require food and should therefore be regularly fed with low concentrations of nutrients preferably in the form of diluted organic liquid fertilizers or pellets.

It is propagated vegetatively by rooting fresh semi-hardwood tip or heel cuttings. Cuttings are rooted in multi-trays on heated benches under mist spray. Cuttings are rooted in autumn or spring in a rooting medium of equal parts bark and polystyrene chips. A semi-hardwood rooting hormone is used to aid the rooting process.

This species grows easily from seed sown in well-drained, acidic, sandy soil and subjected to smoke treatment. Seed is normally sown from late summer into autumn, i.e. March to May.
