Karapule

Light Conditions:

Karapule thrives in full sun.

• Full Sun:
  Ideally, keep Karapule in 6 to 8 hours of direct sunlight daily.
• Partial Shade:
  In very hot or dry coastal areas, light afternoon shade helps protect young plants from leaf scorch.

Temperature and Humidity:

• Warm Temperatures:
  Native to tropical and subtropical climates, Karapule grows best in temperatures between 24°C to 32°C. It tolerates mild cool spells but should be protected from temperatures below 10°C (50°F).
• Moderate to High Humidity:
  The Caribbean’s moderate to high humidity supports lush, vigorous growth.

Soil:

• Karapule prefers well-drained, fertile soil with a slightly acidic to neutral pH (6.00 to 7.00).
• Loamy or sandy soils enriched with organic matter or compost encourage strong root development.
• Avoid waterlogged conditions, which cause root rot.
• Karapule naturally thrives from sea level up to elevations of about 1,600 metres, flourishing in a wide range of environments including dry lowland woodlands, moist forests, evergreen and deciduous forests.
• Mulch (such as grass clippings and wood chips) can be added to the surface of the soil to retain moisture and keep down weeds.

Watering Frequency:

• Regular Watering:
  Water regularly but moderately—about 2 to 3 times per week during dry weather, ensuring the top inch of soil dries slightly between watering.
• Rainy Season Watering:
  In the rainy season, reduce watering to prevent soggy roots.

Amendments and Fertiliser:

• Balanced Fertiliser:
  Feed every 4 to 6 weeks during the growing season (spring to early autumn) with a balanced organic fertiliser or fish emulsion.
• Added Leaf Production:
  For more leaf production, use fertilisers higher in nitrogen (e.g. 3-1-2 NPK ratio).
• Compost:
  Apply compost or well-rotted manure around the base yearly to enrich soil.

Pruning and Maintenance:

• Prune lightly to shape the plant and encourage bushy growth.
• Remove dead, weak or crossing branches regularly.
• Pinching off the tips of new shoots encourages more leaf growth and helps maintain a compact form.

Pest and Disease Control:

• Pests:
  Common pests include aphids, scales, whiteflies and spider mites. Control them using neem oil, insecticidal soap or a mild organic pesticide.
• Diseases:
  Avoid overwatering to prevent fungal issues like leaf spot or root rot. Ensure good air circulation around the plant.

Harvesting Methods:

• Harvest mature, dark green leaves by snipping off entire leaf stalks rather than individual leaves.
• Regular harvesting encourages new growth.
• Leaves can be used fresh, dried or frozen for later use in cooking.

Propagation:

Karapule can be propagated either by either seed, stem cutting, root suckers or by air layering. Here's how to do each:

• By Seeds:
  Seed propagation remains the most reliable for high germination and vigour. It is best done in late spring to early rainy season, when temperatures are warm (above 25°C). Use fresh seeds from ripe black fruits. Remove the pulp and wash thoroughly. Fresh seeds germinate best within 1 to 2 weeks of harvest. Plant seeds about 1 cm (½ inch) deep in a well-draining mix of sand, compost and topsoil. Keep the soil moist but not soggy. Plants usually germinate between 2 to 4 weeks. Once seedlings reach about 10 cm to 15 cm (4 to 6 inches), transplant them into individual pots or directly into the ground in full sun.
• By Stem Cuttings:
  Cuttings and root suckers are practical for quicker multiplication under tropical humidity. This method is best done in late spring to early summer. Select semi-hardwood cuttings about 10 cm to 15 cm (4 to 6 inches) long with 3 to 4 leaf nodes. Remove lower leaves. To improve success rates, dip cut ends in a rooting hormone. Use a well-draining mix of sand and cocopeat or perlite. Maintain high humidity by covering with a plastic dome or misting regularly. Place in bright, indirect light. Plants usually root between 4 to 8 weeks depending on temperature and humidity. In the Caribbean, where humidity is naturally high, cuttings root more easily if kept in a shaded, warm area with consistent moisture.
• By Root Suckers or Offshoots:
  Cuttings and root suckers are practical for quicker multiplication under tropical humidity. Mature curry leaf plants often produce small shoots from the base. These can be gently separated during repotting or early rainy season when soil is moist. Transplant into pots or new beds and keep shaded until new growth appears.
• By Air Layering:
  Choose a healthy, mature branch. Remove a small ring of bark, wrap with moist sphagnum moss and cover with plastic wrap. Roots develop within 4 to 6 weeks in warm Caribbean conditions. Once rooted, cut below the new root zone and transplant.
