Heather 'Winter Chocolate' Calluna vulgaris 'Winter Chocolate'

Water

Heather 'Winter Chocolate' should be kept consistently moist, but not waterlogged. The amount of water will depend on climate conditions, but generally, it requires watering once or twice a week. During hot, dry spells, water thoroughly to maintain moisture, using about 1 gallon of water per plant for each watering session. In less arid conditions, or with natural rainfall, reduce the frequency to prevent root rot. Always check the top inch of soil for dryness before watering.

Light

Heather 'Winter Chocolate' thrives in full sun to partial shade. The best spot is where it can receive at least 6 hours of sun daily. An east or west-facing location that avoids the harsh midday sun is ideal, as it will provide the light requirements without causing scorch to the foliage.

Temperature

Heather 'Winter Chocolate' is quite cold-hardy, tolerating temperatures down to 10°F. The ideal growing range lies between 60°F and 70°F during the growing season. It can survive brief periods of higher temperatures, but sustained heat above 80°F can stress the plant.

Pruning

Prune Heather 'Winter Chocolate' after flowering to maintain shape and encourage bushy growth. The best time for pruning is late winter or early spring, but it is generally done once a year. Remove dead flowers and lightly shape the plant without cutting into old wood, as this can prevent new growth.

Cleaning

As needed

Soil

Heather, commonly called 'Winter Chocolate', thrives in well-drained, acidic soil with a pH between 4.5 and 5.5. The best soil mix should consist of a combination of peat moss, sand, and loamy soil to ensure proper drainage and soil structure. Perlite can be added to improve aeration. Mulching with pine needles or wood chips can help maintain the desired acidity and moisture levels. Regular soil testing is recommended to adjust pH and nutrient levels as needed.

Repotting

Heather, also known as 'Winter Chocolate', should be repotted every two to three years to refresh the soil and prevent root crowding. The best time for repotting is in the early spring before new growth begins. When repotting, gently tease out the roots and place the plant in a slightly larger container with fresh, acidic soil mix.

Humidity & Misting

'Winter Chocolate' heather prefers moderate humidity levels, similar to its native environment on moorlands. While it can adapt to varying humidity conditions, it does best with a humidity level between 40-60%. If grown indoors, a humidifier or regular misting can help achieve these conditions, but ensure good air circulation to prevent fungal diseases.

Suitable locations

• Indoor

  'Winter Chocolate' heather needs bright light, cool temps, and moist acidic soil.

• Outdoor

  Plant 'Winter Chocolate' heather in sun/part shade with well-drained acidic soil.

• Hardiness zone

  5-7 USDA

Life cycle

Calluna vulgaris 'Winter Chocolate', commonly known as Heather or Winter Chocolate Heather, begins its life cycle as a seed, which germinates in well-drained acidic soils with adequate moisture. Upon sprouting, it enters a vegetative stage, developing woody stems, narrow leaves, and in summer, it produces small bell-shaped flowers that can attract pollinators. After pollination, the plant produces seed capsules, which release seeds in late autumn to complete the reproductive cycle. Heather is an evergreen shrub, so it retains its bronze-green to reddish foliage throughout winter, adding year-round interest to gardens. With time, it matures and spreads, forming dense, low-growing mounds that can live for many years with proper care. Eventually, as the plant ages, it might become leggy and woody, at which point it can be rejuvenated by pruning to encourage new growth.

Propogation

• Propogation time

  Late Winter - Early Spring

• The most popular method of propagating Heather, especially the Calluna vulgaris 'Winter Chocolate', is through semi-hardwood cuttings. This process typically takes place in late summer. To propagate, one would cut a piece of semi-hardwood, which is a stem that is not brand new but not fully matured, approximately 4 to 6 inches long. Remove the leaves from the bottom half of the cutting and dip the cut end into a rooting hormone. Place this cutting into a pot filled with a mixture of peat and perlite or coarse sand, ensuring that the leafless part of the stem is buried. The pot should then be covered with plastic to retain humidity, and placed in indirect light. Cuttings should root within 4 to 8 weeks, after which the plastic can be removed and the new plant gradually acclimatized to outdoor conditions before final planting.
