Position
Chocolate Douglahs require a long, hot growing season. Ideal daytime temperatures range from 24 to 32°C, and nighttime temperatures should not drop below 15°C.
Full sun — at least 6–8 hours of direct sunlight daily. Space plants 45–60 cm apart.
Soil
Well-draining soil (sandy loam preferred) pH between 6.0 and 6.8, and rich in organic matter.
Add half a bag of our Volcanic Rock Dust (R25 per bag) and a bag of Superfrass (R25 per bag) to assist in rapid growth.
Watering
Consistent moisture is crucial, but the soil must not be waterlogged. Allow the top layer to dry slightly between waterings.
Mulching
Maintain moisture and suppress weeds with organic pine bark mulch. Pine Bark Mulch adds acidity to the soil.
Add a thick layer of pine bark mulch, keeping it about 20 to 30 centimetres away from the tree trunk (any closer may cause excess moisture and damage the trunk). This will retain the moisture in the soil and will prevent weeds from taking over.
Add magnesium (e.g., Epsom salts) if the leaves are yellow.
Fertilsing
Use a balanced fertiliser throughout the growing season, especially once the plants flower. A fertiliser with a higher potassium level can also support fruit production and development.
Alternatively, use our slow-release all-plant fertiliser. Apply one teaspoon every 4-5 months. The roots will absorb what they need.
Pruning
Pruning is not essential but light pruning encourages bushier plants and better airflow, reducing the risk of disease.
Pests and Disease Management
Monitor for common pests such as aphids, spider mites, and pepper weevils. Spraying with agricultural Neem Oil or Effective Microorganisms (EM Control ) will assist in either prevention or after the fact. If you already have aphids or mites, wash the bush with a harsh hosing, and when dry, spray with Neem oil or EM Control.
Chocolate Douglah plants can become heavy with fruit — staking, or caging helps support them.
Harvest
Peppers turn from green to a rich chocolate brown. Harvest when they feel firm to the touch. Use scissors or pruning shears to avoid damaging the plant.
Chocolate Douglah grows slowly, especially in cooler conditions. Be patient. They appreciate some humidity but need good airflow to prevent fungal diseases.
