I HAVE SEVERAL LOOFAH PLANTS, QUITE VINY AND HEALTHY BUT NO BLOOMS. IT’S NOW LATE AUGUST. WHAT HAVE I DONE WRONG? OR IS THERE SOMETHING I CAN DO? THANKS FOR ANY HELP.

Sometimes if plants are leafy but have no blossoms or fruit it is because the plant is putting it's energy into creating more leaves. If you prune it, it may focus it's energy on producing blossoms instead.

Loofa need a long time to mature. 5 months or more. I planted mine late this year. Late May. They were full vines without flowers until late July. Now they are full of flowers and loofa. I am not sure how late you planted them but they may just not be mature. Another thing may be too much nitrogen in the soil.switch to phosphorus based to get the plants focused on flowering.
