All my dahlia tubers were very healthy. Planted in mid July in a sandy area I've set aside as a pollinator garden, they've all formed foot tall shrubby growth. We've had 90-100 temps and no rain since the day they were planted, so I'm very pleased they are doing great. I look forward too seeing them bloom in fall before the weather finally cools.
I have planted them all and they have come up. I can't wait for them to bloom.
