On this year’s to-do list of techniques to master is bare rooting plants for winter dormancy. To that end I have about 50 willow cuttings, probably 30 haskaps cuttings, and if the Romeo root cherry cuttings put up good growth i may bare root some of those as well. Heck I should get some currants going…
Is there an optimal trunk caliper based on species?
Here we can hit the -20’s (f) so the dirt pile where I plan on heeling them will be frozen solid. They obviously can cope with that but beyond keeping them under snow and protected from the drying wind (and rodents), is there anything else to take into consideration?
Last but not least, are there guidances on building the greenhouse equivalent of a bare root storage cellar? I have a shaded east wall on the house. I could dig a few feet next to the wall, line the bottom with insulation, build the sides with cement, and install slightly insulated cellar doors. It would not be a whole lot of space but enough to put dirt and have some of the heat irradiating from the house keep it a few degrees warmer than the exposed outside.
