WaterThe Spanish Heath, Erica australis 'Riverslea', prefers consistent moisture but does not like to sit in waterlogged soil. It should be watered thoroughly whenever the top inch of soil feels dry to the touch—approximately once a week, depending on climate conditions. During the hotter seasons or in drier climates, it may require more frequent watering, such as twice a week. When watering, aim to provide about 1 gallon of water per plant, ensuring even distribution around the base. In winter, reduce watering since the plant's growth slows and it requires less moisture.
LightSpanish Heath thrives best in full sun to partial shade conditions. It should be placed where it can receive at least four to six hours of direct sunlight daily. An ideal spot would be one where the morning sun is direct and the afternoon sun is dappled or partially shaded to protect the plant from the intense heat of the day.
TemperatureSpanish Heath is hardy and can withstand a range of temperatures but prefers a cooler climate. It can survive minimum temperatures down to around 25°F and maximum temperatures that do not consistently exceed 75°F. For optimal growth, maintain an environment around 60°F to 70°F, which is typically well within the comfort range of this plant.
PruningPruning the Spanish Heath is important to maintain its shape and encourage new growth. It should be pruned immediately after flowering, which typically occurs in early spring. Cut back about one-third of the growth to keep the plant compact. Pruning every year or every other year is sufficient, and it is best done when new buds begin to form.
CleaningAs needed

Life cycleErica australis 'Riverslea', also known as Spanish heath, begins its life cycle when seeds are dispersed from mature capsules, often germinating following a disturbance such as fire which breaks seed dormancy. Seedlings establish themselves in well-drained, acidic soils, and within a few years, the plants reach maturity, characterized by robust bushy growth with needle-like leaves. Spanish heath flowers mainly in spring, producing bell-shaped pink, white or purple flowers that attract pollinators and subsequently allow cross-pollination. After pollination, the flowers develop into seed capsules which remain on the plant throughout the summer and autumn. Over time, these seed capsules open to release seeds and continue the reproductive cycle. With proper care and favorable conditions, Spanish heath can live for several years, going through multiple flowering and seed-setting cycles.
PropogationPropogation time
Spring to Summer
Erica australis 'Riverslea', commonly known as Spanish Heath, is typically propagated through the method of semi-hardwood cuttings. This technique is best performed in late summer. To propagate using this method, a gardener would take a cutting of about 3 to 5 inches (approximately 7.6 to 12.7 centimeters) long from a healthy, semi-hardwood stem, ensuring there are several leaf nodes on the cutting. The lower leaves are removed, and the cut end is often dipped in rooting hormone to encourage root development. The cutting is then planted in a mixture of peat and perlite or sand, providing good drainage and aeration. It's important to maintain consistent moisture and provide a warm environment, but not in direct sunlight, while the cutting establishes roots. This process can take several weeks, after which the rooted cutting can be transplanted.
