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.

You can purchase luffa seeds from www.greenpatchseeds.com.au. Mine have grown extremely well - I only planted seeds in a few separate places and now I have more luffas than I can use! Fantastic plant!
