I was just given a huge jar of very healthy looking loofah seeds. Our cold frame just collapsed after six years of heavy use and we don't have funds for another one. Would it be possible to plant the loofah seeds in peat pots in April and still harvest loofah by fall?

I grew Luffa's in ACT, hoping maybe to get some loofahs from them. They took a while to really get going (after a good rain) then the vine took off, but wasn't til towards the end of Summer that any flowers finally came on. I was surprised they actually formed fruit, and thought it was too late by then anyway, but then they grew & grew, and even into Autumn, the vine & fruit were still green and growing well. I didn't do anything particular to help them grow, but perhaps will try pinching the tips to encourage more female flowers next year! I was going to leave them on the vine to dry, but a few mornings of frost put an end to that. I took off the large fruit, and the next day, the frost had killed the vine anyway. I am trying to dry the fruit out on the sunny laundry windowsill, and hope that does the trick!
