Luffa Sponge Gourd Seeds - 20 Seeds for Home Growing

Grow Your Own Luffa Sponges

Discover the original luffa sponge gourd seeds, perfect for producing large fruits on vigorous climbing vines that can reach up to 20ft. These UK-sourced gourd seeds are slow to start but thrive in warm weather, yielding sponges for harvesting from late July to August.

Sow in April with pre-soaked seeds in a heated propagator, and transplant outdoors after frost. They need full sun, sturdy support, and minimal feeding to avoid reduced crops. Keep plants moist in summer and stop watering in autumn as fruits mature and dry.

Harvest before the first frost, dry the gourds, and easily extract the wet, white sponge by breaking the end cap and pulling the vascular bundle. Rinse and bleach for whitening—ideal for eco-friendly, home-grown sponges.
