FAQs

How do I harvest loofah for sponges?

Allow fruits to fully mature and dry on the vine until the skin yellows/browns. Peel off the outer skin, shake out the seeds, rinse the fibrous core to remove pulp, and dry thoroughly.

Do loofah plants need a trellis?

Yes. Provide a strong trellis, fence, or arbor. Vines can reach 6–10+ ft (2–3+ m) and heavy fruits need support.

Will loofah grow in cooler climates?

Yes, as an annual. Start seeds indoors early, transplant after frost, and consider using black mulch, a warm microclimate, or a greenhouse to ensure a long enough season.

Are young loofah fruits edible?

Yes. Harvest when small and tender; use like summer squash. Mature fruits are for sponge production.

Can I grow loofah in containers?

Yes. Use a large container (at least 5–10 gallons) with rich, well-drained mix and a sturdy trellis.

How many seeds are in a packet?

Packet sizes vary by the option you select on this page. See the product variants for details.
