Erica croceovirens is ideal for warm, sunny gardens. It is easily grown from fresh seed which should be sown in late summer or autumn. Germination is greatly enhanced by the application of smoke which mimics the conditions in nature. Sow seeds onto a well-drained, slightly acidic growing medium consisting of a combination of river sand and well decomposed pine bark in roughly equal proportions. Seeds germinate in about six weeks, emerging as tiny, delicate plantlets that must be lightly watered with a watering can. Let the seedlings grow to about 10mm tall before pricking them out into small individual pots. Young seedlings are encouraged to grow by feeding them every week with a diluted organic fertiliser. It is advisable to plant out during the cooler autumn or early winter months to allow the plants to establish before the onset of summer.

This species is, relative to other ericas, easy to root from cuttings because plants produce good rooting material in the form of side shoots near the ends of main stems. Cuttings are rooted in autumn or spring, in multi-trays on heated benches under mist spray. Select small tip or heel cuttings about 20-30mm long, taking thin wood from the previous season's growth. Heel cuttings are preferred where a short side shoot is removed from the stem. The base of the cutting is treated with a rooting hormone for semi-hardwood cuttings which are then placed into a rooting medium of 50:50 fine-milled bark and polystyrene or perlite pellets.

The saffron heath grows in acidic well-drained soils in full sunlight. It is tolerant of a range of habitats including rockeries, embankments, or just a normal, sunny, garden bed. Good watering once a week during summer months is recommended for the first year after planting.

It grows well in containers, provided that the correct, well-draining growing medium is used. 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 living in poor soils, but, for best results, should be regularly fed with diluted organic liquid or small amounts of organic pellet fertilisers (5:1:5) that are low in phosphorus.
