Luffa is a tropical/subtropical cucurbit vine grown for edible young fruit (eaten as a vegetable) and mature dried fruit (natural sponge). Two species are cultivated: smooth luffa (L. aegyptiaca) primarily for sponges, and ridged luffa (L. acutangula) primarily for eating. Requires a long, hot growing season and a strong trellis. Honest limitation: luffa is not viable south of about Sydney without a greenhouse.

How to Grow Luffa in Arid / Semi-Arid Australia
When to Plant
Transplant October-November. The heat suits luffa well if heavily irrigated. Season is long enough for sponge production in most arid areas.
- Soil
- Rich, well-drained soil with generous compost and aged manure. Heavy feeder like most cucurbits.
- pH Range
- 6.0-7.0
- Sunlight
- Full sun (minimum 8 hours). The more sun and heat, the better.
- Spacing
- 120cm apart, 200cm between rows
- Watering
- Very heavy water demands during fruiting. Deep, consistent watering essential. Drought stress causes flower drop and misshapen fruit. Drip irrigation recommended.

How to harvest: Eating: cut with secateurs. Sponges: cut from vine when completely dry. If frost threatens before sponges are ready, cut and bring indoors to finish drying.
