Internet search where to buy luffa, or seed suppliers on-line

I live in a very hot long summer rainfall with a short very cold (black frost at least once in winter) area. When is the best time to plant my Loofah seeds?

I live in Gordonsbay,Western Cape. Can I plant my seeds in trays now and transplant into the garden after winter into bigger pots

Maybe leave it until mid winter as you plant out seedlings when about 4 weeks old. But your soil temps maybe too cold then. Check what time of the year you should plant.

Very difficult, this plant needs a very long growing season with warm soil, at least 65 F. If you try this, be certain to start indoors 4-6 weeks before last frost. Use biodegradable starting pots and plant out when you are absolutely certain there will not be another frost. Provide full sun for as much of the day as you can. At harvest time wait until fully dried on the vine or if there is a risk of frost, harvest immediately, even if it is still a green pod. Good luck.
