Gotcha! i had read it as they have a better chance of growing staying in the pots. I love getting whopper sized bare root roses in the mail...in March. After April or so, I'm stuck with buying locally in pots, because shipping costs with pots are just too high, and I don't want chopped up roots. Or I'm too cheap, I guess. This has been a freaky year here. We don't normally have extreme heat in June. July, yes, but not June.
I'll remember your observations on Rise and Shine and try to do better at keeping the root balls intact. That makes sense.
