How to Grow Bitter Gourd
Growing bitter gourd is relatively straightforward, making it a rewarding plant for home gardeners. Here’s a step-by-step guide:
1. Selecting Seeds
Choose high-quality bitter gourd seeds from a reputable supplier. There are several varieties of bitter gourd, so select one that is well-suited to your climate and growing conditions.

3. Planting Seeds
Sow seeds directly in the garden once the soil has warmed up, typically in late spring or early summer. Plant seeds about 1 inch deep and space them 12 inches apart. If you are starting seeds indoors, plant them in biodegradable pots 3-4 weeks before the last frost date.
4. Providing Support
Bitter gourd plants are vigorous climbers and require support to grow. Provide a trellis or fence for the vines to climb, which helps in better air circulation and sunlight exposure, reducing the risk of diseases.
5. Watering
Water the plants regularly, keeping the soil consistently moist but not waterlogged. Mulching around the plants can help retain soil moisture and suppress weeds.
6. Fertilizing
Feed the plants with a balanced fertilizer every 4-6 weeks to promote healthy growth. Avoid excessive nitrogen, as it can lead to lush foliage with fewer fruits.
7. Pest and Disease Management
Keep an eye out for common pests like aphids, fruit flies, and whiteflies. Use organic pest control methods, such as neem oil or insecticidal soap, to manage infestations. Regularly check for signs of diseases like powdery mildew and downy mildew, and treat promptly with appropriate fungicides if necessary.
8. Harvesting
Bitter gourd fruits are typically ready to harvest 2-3 months after planting. Harvest the fruits when they are young and tender, as they become more bitter with age. Use a sharp knife or pruning shears to cut the fruits from the vine, leaving a small stem attached.
