Winter Heath Erica carnea 'Rubinette'

Water

Winter Heath should be watered regularly to maintain evenly moist soil, especially during its growing season in the spring and fall. It's best to water the plant when the top inch of soil feels dry to the touch. Depending on the climate and weather conditions, this may mean watering once every week or two. When watering, thoroughly soak the soil until water runs out of the bottom of the pot or the ground is damp at a depth of about 6 inches. Be cautious not to overwater, as Winter Heath doesn't like sitting in waterlogged soil. In general, during hot and dry periods, increase the frequency of watering, and reduce it during cooler, rainy spells. It might be helpful to use about one gallon of water per plant each time during peak summer months, adjusting as needed based on weather and soil conditions.

Light

Winter Heath thrives best in full sun to partial shade. It's important to provide the plant with at least four to six hours of sunlight daily, making a spot that receives morning sun and afternoon shade ideal. Avoid deep shade locations because insufficient light can result in poor flowering and leggy growth.

Temperature

Winter Heath prefers cool temperatures and can tolerate a wide range from about 20°F to 70°F. The ideal temperature conditions for robust growth and flowering lie between 40°F and 60°F. This plant is quite hardy and can survive winter chills down to 0°F, making it suitable for gardens in cooler climates.

Pruning

Winter Heath can be pruned to maintain shape and encourage bushier growth. Pruning should be done immediately after flowering, which is usually in late winter or early spring, to avoid cutting off next season's buds. Lightly trim back the tips of the branches, removing any spent flowers and any dead or damaged wood.

Cleaning

As needed

Soil

Winter Heath (Erica carnea 'Rubinette') thrives in acidic soil with a pH of 4.5 to 5.5. A well-draining mix consisting of peat moss, sand, and loamy soil is ideal. It is essential to ensure good drainage while retaining moisture, as the roots are fine and shallow.

Repotting

Winter Heath typically does not require frequent repotting as it enjoys being slightly root-bound. It may only need repotting every 2 to 3 years, or when you observe that the plant has outgrown its current container.

Humidity & Misting

Winter Heath prefers moderate humidity levels but is quite adaptable and can tolerate lower humidity typical of temperate climates. It is tolerant of outdoor humidity fluctuations and does not require specific indoor humidity adjustments.

Suitable locations

• Indoor

  Provide bright light, acidic soil, and keep cool indoors for Winter Heath.

• Outdoor

  Plant in acidic soil, partial sun/shade, and mulch for Winter Heath.

• Hardiness zone

  5-7 USDA

Life cycle

The life cycle of Erica carnea 'Rubinette', commonly known as Winter Heath or Spring Heath, begins with seed germination, typically occurring in warm, moist soil conditions. Following germination, seedlings establish themselves and enter a vegetative growth phase, where they develop a dense mat of evergreen foliage. As the plant matures, it enters the flowering stage, where 'Rubinette' produces its distinctive deep ruby-red flowers from late winter to early spring. After pollination, often by bees and other insects, the flowers develop into small capsules containing tiny seeds. The plant then goes into a period of dormancy during the summer, conserving energy and water. With the arrival of suitable conditions in subsequent seasons, Winter Heath will repeat its flowering cycle, continuing its life span for many years as a perennial shrub.

  Spring-Early Summer

• The most popular method of propagating Winter Heath 'Rubinette', scientifically known as Erica carnea 'Rubinette', is through semi-hardwood cuttings. This is typically done during the late summer months. To propagate, a gardener would take a cutting of about 2 to 4 inches (5 to 10 centimeters) from the current year's growth, ensuring that several leaves are left on the cutting. The lower leaves are stripped, and the cutting's base is dipped into rooting hormone to encourage root development. Then, the cutting is planted in a well-draining soil mix, lightly watered, and covered with a plastic bag or placed in a propagator to maintain humidity. Roots usually form within a few weeks to several months, depending on environmental conditions. Once the cuttings have rooted and show new growth, they can be transplanted to a larger pot or into the garden.
