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

will lofa grow in my zone?

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.

Can I grow Luffa in Bellingham Washington? What sorts of yields can I expect?

If I plant a seed, preferably 2 and put it out doors in June, will it have enough time to produce a vegetable by the first frost in November? It is August and I just got my first vegetable to start to grow. It took along time for nature to do the cross pollination. Thank you, Linda from Virginia Beeach
