We had a lovely warm autumn this year and I just couldn't bring myself to do the chore of mulching! Some of the roses were still GROWING as late as early December and I figured that covering them up and effectively warming them , would just keep them going even longer. Then we had a dump of snow and it was too late for mulching.
I'll have to race out there with my peat moss and cover the guys if we get any big thaw! Right now they should be quite snug in about 60cm of snow.
This frost-heave-thing sounded like a tale you tell to naughty children - or ignorant immigrants when we first moved here. We were marvelling at crumpling rocks and shattered bricks and the dreaded term frost damage came up. The sight of rocks littering the fields with plenty more lining the sides - now, why did they leave those behind?? Well, they were still in the ground when the others were moved!!
