  • Space plants: 45 - 75 cm apart

  • Luffa on vine

This type of squash while not strictly a vegetable can be eaten when young. They are more commonly grown to use when mature and dried.

The plants need warmth to grow successfully. Keep inside until all risk of frost is gone.

They grow on vines similar to cucumbers.

A large loofa makes a great back scratcher. Luffa can be cut into many shapes for scrubbing pads, padding, and other uses.

Culinary hints - cooking and eating Luffa

The luffa flowers and fruits are soft and edible when young and are sometimes cooked and eaten like squash or okra. Loofah has been an important food source in many Asian cultures. The leaves and vines should not be eaten.

I love to eat the young fruit when they are about 1" to 1.5" in diameter. But after that, let them grow until they turn completely brown on the vine. Then pick the brown (dried) fruit and soak in water a couple of minutes. The skin will peel off very easily after it has been soaked. If you do not soak them first, the skin will be more difficult to get off.

Im in 7a & planted luffa in mid-April. They look great & are all over the trellis. Lots of clusters of male & female flowers. Zero established gourds yet & it's mid-August. I planted w/ the expectation of a harvest around late September mid-October. Should I be concerned by the lack of gourds at this point? It is the only thing i planted & i have a lot of time in on them. Everything looks totally healthy (this is in an organic community garden) but i'm feeling worried that this is going to end up being a race against the weather and i wont have any gourds at all? Any input, guidance, or thoughts are welcome!

I buy mine on Seeds for Africa (online shop). They are currently out of stock but will come back in stock late September or early October, just in time to sow them (I asked the staff, as I'm looking to buy some too). Just be careful to not sow them too late (buy as soon as they come in stock). To avoid delivery fee, you can collect the seeds at their shop. The seeds are also available on Seeds and Plants South Africa (online shop), but the delivery fee is quite high on that website. Hope this helps.
