Is this sustainable or should I chop and replant? Rethinking American Beauty due to cold susceptibility
American Beauty used to be the backbone of my modest DF garden. I say “used to” because the cold winters here in North Central Florida have cut me down to only 2 surviving plants (had 11 going into this winter).
And they’re barely hanging on. Below is a pic of one of them. The flesh on a low level segment was lost but the cambium is intact and branches are continuing to grow above.
Is this sustainable or should I chop what is viable and replant? AB has shown very poor cold hardiness compared to my other varieties and I think I may just stick with a 4-banger pot of it.
Please disregard how unkempt it is — I am letting some things grow out for potential propagation pieces while I sort things out, so it’s a little wild right now. Trying to figure out a long-term solution.
Also, I am going to give up on trying to protect my DFs in the winter outdoors and will be figuring out a way to muscle them into the garage next winter. 2 winters ago was tough, but this last one was brutal, multiple nights into the teens that my tarp greenhouse could not withstand.
If anyone has any recommendations on what they consider the most cold-hardy variety, I am all ears. Haley’s Comet and Phys Graffiti held up pretty well this year. As did sugar dragon and condor. AB just got decimated.
