| I am going to mound up mine after they lose their leaves and go dormant. Cold weather triggers them to make their own sort of antifreeze, so they should be allowed to get cold and go dormant before being mounded. I will probably mound mine with wood shavings, clean stall shavings from the farm store. Then cut back any dead/damaged canes in Spring, and do any pruning to get the shape I want. You should have already had your first hard freeze, right? We had ours in mid Sept. and I'm in the southern part of Colorado. Some of the minis are still trying to bloom, though, and none of them are dormant. |
