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.

What accommodations should I make for growing Luffa in 8b?

We live in zone 8a and the biggest challenge for us when we grow Luffa is that they climb SO high and fast in the summer. I'd suggest planning on some serious trellising as the Luffa gourds get pretty heavy before they dry out.

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.

Would loofah be ok to grow near rhubarb and kiwi berries?

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?
