I planted a replacement last year around July 4 th. She did just fine. Maybe not quite the monster as the ones planted in May, but I was definitely pleased with the results of planting a teenager into the ground in July. Good luck

What if it wasn't just a teen, but a 3ft nice bush in a pot beginnning of July....and the plant could very well continue living in this pot....would it better to replant into the ground?

Do roots still grow and expand during flowering? I imagine the transplant will take two weeks of root growth away cause the change of environment....so assuming flowering is "triggered" at end of July...are those two weeks of new ground roots worth the loss of 2wks of solid container root growth?
