With a heater failure in Jan. and a complete die back of all my greenhouse stock including this bearing Reed, I thought I had lost it. Temps went down to 18F, for how long I don't know. I think the heavy mulch and thick canopy was enough of a heat blanket to save it and more importantly it had been acclimated to low/mid 30F temps days before the big one hit.
Stump in March 6:
August 15. This is a big tree with 3 trunks now. Photo doesn't do it justice. It's in a raised bed, a bottomless 100 gal. RootBuilder pot which is dwarfed by this tall and wide gorgeous tree. There's not a blemish anywhere on it and fast approaching the 10' gutter.
I don't know what happened to all my greenhouse trees that survived but it's like they're on steroids now. I had a complete die back of my citrus. I now have a key lime that I've grafted 3 orange varieties to, persian lime, limequat, etc. that's 9' tall. Fertilizer has been like always, a slow release pill, this year Osmocote Indoor/Outdoor, 6 mo.
