About Luffa
Luffa aegyptiaca is an annual climbing plant from the cucurbit family, known for its elongated fruits that, when mature and dried, reveal a fibrous structure used as a natural sponge. Its large palmate leaves and yellow flowers make it attractive on pergolas or fences, where it can grow freely. Besides its cosmetic use, young fruits are edible and enjoyed in various tropical cuisines.
Native range
Tropical and subtropical Asia, possibly India or Southeast Asia
Care tips
It requires full sun and rich, well-drained, consistently moist soil; watering should be regular and abundant, especially during flowering and fruiting. A sturdy support is needed for climbing, such as a pergola or trellis, allowing fruits to hang freely and develop properly. Planting is done after the last frost, when soil temperatures exceed 20°C. Avoid waterlogging, as it can lead to fungal root diseases.

- Check drainage, reduce watering if waterlogged. If dry, water deeply. Protect from intense direct sun if leaves are burning.
- What kills it
