You have male and female flowers on plants, The one with the little fruit is the female. Pobably no bees. Try hand pollination.

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.

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?

For Gardenate : Young seedlings can be affected by sudden changes of temperature. To prevent this seedtrays are usually kept under cover for a few weeks. Any area which mantains even, frost-free, temperatures 24 hours will do. e.g. Unheated greenhouses, a covered area close to the house, or small frames covered with frostcloth or with a piece of fabric like old bed sheets. If possible put the trays above ground level. Too much strong sunlight can do as much damage as cold nights to seedlings.
