Lovely pictures, Lin and sure hope this short cold snap doesn't zap too many of our flowers! The ground is plenty warm after the weather we've had, so that will help a lot.
I have that big urn with the Philo Pastazanum on a dolly, and can roll it right to the patio door, so plan to do that right before going to bed, and haul it into the house. It's huge, but the urn is plastic so not too terribly heavy.
I've been the last two hours schlepping 30 orchids into the house and deploying the big frost tent over my Earth Boxes. I think I have everyone under cover that really needs it now. Although I do have one big white brug in full bloom that is just too unwieldy to move or cover. It will just have to tough it out. Greenhouse shelf units zipped, tent unfurled, brug Monster White giving me a big guilt trip . . .
