Soil, pH, and Climate Requirements for Bitter Melon (Indian - Rough)

Bitter Melon thrives in tropical climates with warm temperatures and high humidity. It requires well-draining soil enriched with organic matter for optimal growth.

Proper field preparation, with an emphasis on well-draining soil textures, is crucial to prevent root diseases.

Step-by-Step Planting & Propagation

1. Seed Selection: Choose disease-free seeds from reputable suppliers. Soak seeds overnight in warm water to improve germination rates.
2. Site Preparation: Prepare raised beds or mounds to enhance drainage. Incorporate well-rotted compost to improve soil fertility.
3. Sowing Seeds: Sow seeds at a depth of about 2.5 cm (1 inch) when the soil warms to 21°C (70°F).
4. Spacing: Ensure adequate spacing of 30-50 cm (12-20 inches) between plants and 180 cm (6 feet) between rows.
5. Trellising: Install a trellising system as plants begin to vine, which supports air circulation and fruit development.

Pests, Diseases & Organic Management

Bitter Melon is susceptible to pests such as Spider Mites, aphids, and cutworms. Common diseases include powdery mildew and cucumber mosaic virus. Effective management includes:

• Companion Planting: Encourage beneficial insects by planting Nasturtium and Marigold.
• Neem Oil: Use as a natural insecticide spray to deter pests.
• Rotational Cropping: Avoid planting in the same location continually to reduce disease incidence.

Harvesting, Curing & Optimal Storage

Bitter Melons are typically ready to harvest 12-16 weeks after planting when the fruits are tender green. To harvest:

• Use sharp scissors or knives to prevent vine damage.
• Store at 10°C (50°F) in a cool, dry place for up to 3 weeks.

Avoid stacking fruits to prevent bruising. Consider extending shelf life by refrigerating individual fruits wrapped in a perforated plastic bag.
