I've been doing this more & more the past few summers. Most of the stuff I've dug up, except for Coleus. And I know well that ground dirt isn't a good medium for pots, but for a lot of this stuff that's only going to be potted for a few months before going back in the ground, I just scoop 'em up & plop in a pot. Try to shovel up a chunk of roots/dirt the same size as the pot. Not for those who might freak out if something crawls out of a pot they've brought into the house, dirt usually has some "bugs" in it. This also has been going well the past few winters, for stuff that was excavated & plopped.
Celene, LOL! Having a terrible time with squirrels tearing up hanging pots. I'm going to have to fill them with plastic forks (tines up) so they can't keep doing that. Try putting some rocks around your newly planted stuff? Squirrels are the busiest & most prolific gardeners on the planet, but dang, they have some weird ideas!
