I have loofah seed that could easily be 40 years old I will try growing them in Gauteng in my sun room, is it possible they will grow?

Hi while all my other gourd plants have died off over winter my luffa seems to be powering on as if it prefers winter and has lots of little luffahs and flowers coming on It doesn't even appear to be affected by frost Is this normal luffa behaviour?

I live in southern Idaho (zone 7) We have had an incredibly cold, wet spring. It is now mid June, would it still be possible to have success planting seeds now?

Luffa need a very long growing season. It is said to need near 200 days. If you look for your first frost date then count back to today and see if you have enough days. Good luck!

I have 3 Luffa plants potted , about 3” tall and healthy. They are ready to be put in ground. Now I am stuck. Full sun, part sun , keep wet, keep dry... central Florida on the river. Please help.

I also have 3 luffa plants. First year growing in north Florida. I put one in full sun, one in part sun and one in complete shade. They are all growing at the same pace but with one exception: the one in full shade has zero luffa. The other two each have 5 very large ones.

Luffa belong to the curcubit family, so you can follow advice for growing zucchini or pumpkins

I've seen YouTube videos with 2 types of loofah. The one with ridges, and a much larger one without ridges. I live in Natal and want seeds for the much larger type. Please advise where I can get these seeds.
