  • Luffa on vine

This type of squash while not strictly a vegetable can be eaten when young. They are more commonly grown to use when mature and dried.

The plants need warmth to grow successfully. Keep inside until all risk of frost is gone.

They grow on vines similar to cucumbers.

A large loofa makes a great back scratcher. Luffa can be cut into many shapes for scrubbing pads, padding, and other uses.

Culinary hints - cooking and eating Luffa

The luffa flowers and fruits are soft and edible when young and are sometimes cooked and eaten like squash or okra. Loofah has been an important food source in many Asian cultures. The leaves and vines should not be eaten.

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?
