Although it is a summer crop, they say to plant seeds Sept onwards. Maybe best to wait until after the last frosts. If you feel your climate is more like temperate use temperate climate zone

No, if you set the above growing zone to USA 9B ( or whatever country you are in) then it says, a. Start seeds indoors in January, transplant in March or place seeds in ground outdoors February/March. It gets too cold in October. And we in AZ in 9B get frost. If you go to Phoenix Backyard Gardening on FB, they might know more.

An internet search might help, try 'loofah' as an alternative to 'luffa'

Hello from Vancouver! Thank you for this wonderful site. I wonder if you could tell me if Loofahs can be grown in this part of the country? It would be great if so. Would they need a greenhouse? Thank you! Martin

I live in Las Vegas Nevada. It gets very hot during the summer months (100 to 120°). Will the loofahs grow here?
