Ok, I had two first year Centennial rhizomes this year. The 101f heat in May killed one. The other survived but barely and it now looks good but has only grown to 8 inches high. Should I assume that if i transplant it at my new home next week, it will do ok next year? Or should i assume that if it only grew to 8 inches in 3 months that it is damaged beyond hope, and just start with new rhizomes next year?
