Wow, you've built that collection in a hurry Art! I know what you mean, can't keep up with moving them out of the wind. And I'm sorry to hear your trees took on damage too. But 30 gallon pots tipping... wow. Mine are mostly 7's and 10's still (and 3 were 15's), the bigger ones approximately "square" (well, they're close to cylindrical, so round in one cross section, but to friendly pistonheads I'd say square because the bore and stroke of the cylinder is about equal, a couple of them oversquare a bit, meaning bigger diameter than height). OK OK, I'm just saying they've got low centers of gravity and nice wide bases. But they blew right over anyway. I checked them out today. Will have to stake a few of them, but won't lose any. Lost quite a few leaves though, and some of the fruit.
