WaterWater your Winter Heath 'Adrienne Duncan' deeply but infrequently, ensuring that the soil is kept evenly moist but not waterlogged. During the active growing season, in spring and summer, water approximately once a week with about one gallon per plant, depending on the weather and soil drainage. Reduce watering frequency in fall and adjust based on rainfall, as overwatering can lead to root rot. During winter, water sparingly and only if there's been a lack of precipitation; once a month with half a gallon should suffice. Always check the top few inches of soil for dryness before watering.
LightWinter Heath 'Adrienne Duncan' thrives best in full sun to partial shade. The ideal location is where the plant can receive at least four to six hours of direct sunlight daily, with dappled afternoon shade in hotter climates to protect the foliage. Avoid deep shade as it can lead to poor flowering and spindly growth.
TemperatureWinter Heath 'Adrienne Duncan' is hardy and can tolerate low winter temperatures, often surviving in conditions as cold as -10 to 20 degrees Fahrenheit. However, the optimal growing temperature range is between 60 and 70 degrees Fahrenheit. Avoid placing the plant where it might suffer from heat stress in temperatures consistently above 80 degrees Fahrenheit.
PruningPrune Winter Heath 'Adrienne Duncan' immediately after flowering to maintain its shape and promote bushier growth. Pruning also helps prevent the plant from becoming too woody. An annual trim, cutting back about a third of the previous year's growth, is typically sufficient. The best time for pruning is late spring or early summer.
CleaningAs needed
SoilWinter heath requires well-draining, acidic soil with a pH between 4.5 and 6.0. A mix of peat, sand, and loamy soil is ideal. Amend with organic material to improve drainage and nutrient content.
RepottingWinter heath typically needs repotting every 2 to 3 years, or when it becomes root-bound. It's best to repot in autumn or early spring to minimize stress on the plant.
Humidity & MistingWinter heath thrives in moderate humidity conditions but is quite adaptable and can tolerate the drier air found in many homes without issue.
Suitable locationsIndoor
Use acidic soil, bright light, moderate water, and cooler temps.
Outdoor
Plant in acidic soil, partial sun, and protect from harsh winds.

Life cycleThe life cycle of Winter Heath 'Adrienne Duncan' begins with seed germination, occurring typically in spring when temperatures are suitable. Seedlings emerge and establish a basic root system and foliage, developing into a small shrub over the first year. As a perennial, Winter Heath 'Adrienne Duncan' enters a vegetative stage where it continues to grow and mature, forming a dense mat of evergreen foliage and reaching full size within 2-3 years. The plant blooms in late winter to early spring, displaying its pink to purple flowers which are pollinated by insects, leading to seed development. After flowering, the plant focuses on energy storage and growth throughout the spring and summer months. The plant enters a period of dormancy during the colder months, reducing metabolic activity to survive winter, and repeating its cycle with new blooms in the subsequent year.
PropogationPropogation time
Late Winter to Spring
The most popular method of propagation for the Winter Heath, scientifically known as Erica carnea 'Adrienne Duncan', is through semi-hardwood cuttings. This typically occurs during late summer. The process involves selecting healthy, semi-ripe shoots that have partially matured. Gardeners will cut pieces of stem about 2 to 3 inches long, ensuring at least two leaf nodes are present. These cuttings are then dipped in rooting hormone powder to encourage growth and planted in a mix of peat and perlite or sand to provide good drainage and aeration. The cuttings should be kept under high humidity, ideally in a cold frame or under a plastic cover, and in indirect light until roots develop, which usually takes a few weeks. Once rooted, they can be potted individually and eventually moved outdoors to acclimatize to garden conditions.
