Hi, Tom:
Your babies are looking great! Mine are a bit larger than yours but mine have to wait a bit for planting out also. Our weather is fine, but I had hand surgery last month.....really bad timing to lose use of your dominant hand at the beginning of the gardening season,
I think you're OK in your present pots, but maybe Shoe will weigh in as he has much more experience with this
I'll try to get some pics this weekend to post of my babies. I planted mine in deep pots since they develop tap roots. I'm hoping I can transplant them without too much disruption.
