When is the best time to sow sponge gourd (gilki, nenua) and what spacing?

Sponge gourd (gilki, nenua) is a warm season cucurbit grown in two windows, a summer crop sown from February to March and a rainy season crop sown from June to July, and it is frost sensitive so avoid the cold months in the plains. Sow seed in pits or lines with two to three seeds per spot, keeping wide spacing of around 1.5 to 2 metres since the vines spread widely. Growing on a trellis or pandal keeps the fruit straight and clean, makes picking easier, and reduces fruit rot compared with letting vines run on the ground. Soak seed before sowing for faster germination. Pick fruit young and tender. Confirm the recommended variety and exact window for your area with the local horticulture office.
