  • Space plants: 18 - 30 inches apart
  • Harvest in 11-12 weeks. Use as a back scratcher.
  • Compatible with (can grow beside): Peas, Beans, Onions, Sweetcorn
  • Avoid growing close to: Potatoes
  • 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 would like to know if the Luffa's require irrigation or a lot of water ? Also how long must one wait until a harvest ? Oh also what is the best soil ph ? and fertilizers used ? Thankyou Peter

I grew Luffa for the first time this year (West Sydney) planted seeds 24 Sept, planted out 8 Oct. Nothing happened until mid Feb, by which time the vines were 20 feet high, started nipping out the growing tips, and any side shoots greater than 3 feet. The vines are flowering like made (male and female). Soil preparation NIL, watered about 1-2 inches per week, mulched with grass clippings, PH is currently 6.4. The biggest Luffa is currently 13 inches long (like a huge lebanese cucumber. Hope this helps future luffa growers.

Loofas wow - grow like crazy with just a fence to run along - eat them when they are like zuchinni size. The vine took off up a tree nearby - a bit hard to pick then. I have seeds coming out my ears. great for getting the dirt off in the bath room.

I'm fascinated at the idea of needing to plant luffa seeds :>) Seeds from dried fruit seem to grow wherever they land for me. Anyone want some?

I have started to grow loffa this year melbourne, I noticed some yellow flowers had boosted a week ago, I was very happy, but I found all baby loffas are going to die because they are all females and there isn't any male flowers to bloom, and yeasterday I had just found some male flowers shoot out next from those died baby loffas, why it dosen't like someone said that the male flowers should come early than the females. Is any one can explain that?

You could, with two caveats: they take forever to mature (like 200+ days), and they take a lot of space (like 6-9 meters). So I think it's too late for you to grow them outside this year, but you could still grow them in a LARGE greenhouse...they set fruit during short days so time your lighting accordingly. Your best bet is probably to start them indoors in peat-type pots in late winter for next year.
