The story

Ridge gourd has been a monsoon vegetable of India for thousands of years, cooked in Gujarati and Tamil kitchens when young and left to dry into the loofah sponge when old; the chutney of its peel is a frugal kitchen's classic.

Planting

Full sun, rich soil, heat, and a trellis; sow seed after the soil warms, an inch deep, and train up.

Growing

Water and feed steadily. Pinch the tip to branch. Harvest often to keep it producing.

Harvest and use

Pick young at 6 to 10 inches while tender; the ridges are peeled and the flesh cooked. Leave some to mature, dry, and peel for sponges.

What to watch for

Fruit fly and powdery mildew.
