due to harsh winter conditions "up north",the most successful method of wintering roses is the "minnesota tip" method. the roses (not shrub) are pruned to about 6to8 inches,all leaves removed,and tied into bundle. a trench is then dug to completely bury plant. plant is then tipped into ditch and thoroughly covered with soil..i winter about 24 hybrid teas each year, rarely suffer any loss.temps here may drop to minus 30 degrees,but roses are safe with this method.
