About Bitter Melon (Karela)

Bitter melon (karela) is a beloved vine vegetable in Indian, Chinese, and Southeast Asian cuisine. The distinctively bitter flavour is valued for digestive and blood-sugar benefits. In cold zones, grow in a greenhouse or as a long-season container crop.

Nick seeds and soak 24 hours before planting. Needs sustained heat — do not plant out until nights are reliably above 60°F. Train on a vertical trellis. Harvest at 4-6 inches while still firm and green — overripe fruits turn yellow-orange and split. Excellent for Indian bhindi-style dishes and stir-fries.
