This erica grows in deep, well-drained, sandy soils, but is adaptable and will grow in a range of soil types. It will also grow in heavier clay soils if there is good drainage and it must be watered less often to allow the medium to dry out between watering. The ideal soil pH is between 5.5 and 6.7, but the soils may range from acidic to neutral.

The Gouriqua heath is easily grown from seed, which should preferably be sown in autumn in the Western Cape. In other regions it should probably be germinated at the beginning of the growing season. Treatment with smoke or smoke extract greatly enhances germination. The seed takes about six to ten weeks to germinate and are delicate in their early stages. It is important not to sow too thickly as seedlings growing too close together and overwatering may result in damping off. The young seedlings should be protected from heavy rainfall and direct sunlight by placing the trays under cover, while still providing good light and aeration. The seedlings should be watered gently to avoid washing them out of the tray or flattening their young delicate stems. Allow the young plants to grow to about 10 mm tall before planting them out into multi-trays or small pots/bags. Plants should be grown up to at least 10 cm before planting out in the garden.

Propagation from cuttings is more difficult and should be done with suitable facilities, such as mist propagation houses with heated benches and overhead misting. Cuttings are preferably taken in autumn in the winter-rainfall Western Cape, but may be taken in spring or early summer as well. Take fresh, actively growing, thin side shoots taken as heel cuttings, that yield the best results. A rooting hormone for semi-hardwood cuttings applied to the cut surface or heel, results in quicker and better rooting. Rooting may take from eight to sixteen weeks and sometimes longer. If the stem tip develops a callous, but not roots, then score the callus and apply more hormone and place in fresh rooting medium. This often results in very good rooting.

Erica baueri subsp. gouriquae is a resilient species that should be suitable for most gardens in South Africa where the humidity is not too high or where there is little or no frost. They also do well in coastal gardens, as long as the soils are acidic and it is not exposed to too harsh salt-laden wind. It grows well in various garden aspects, including open beds, rockeries and on slopes.

Feed before flowering with slow release 3:1:5, or monthly with a good organic seaweed-derived fertilizer. Be careful not to disturb the roots and water regularly as this is generally the cause of losses with ericas. Good results have also been achieved when applying controlled release fertilisers suitable for erica. Be careful not to exceed dosage.

Pruning will increase flower production resulting in splendid displays and increase the life expectancy of the plants. Ericas are relatively short-lived fynbos plants and survive on average up to between 10 and 15 years, after which they need to be replaced.

It is a prolific flowerer and is a wonderful addition to the garden and for attracting sunbirds.
