I cut all the branches (canes) back to about 6 to 8 inches. Cut the bottom out of a round 35 gallon trash can and inverted it over the tree, wide end down. Filled it with cypress bark mulch, making sure it was packed around the branches. Pulled a plastic garbage bag over the can when it became freeze time to prevent the can filling with ice during snows and rains. Removed the bag during warmer days so everything could breathe. Possibly just got lucky but it all came together and I will have really nice, fragrant blossoms until frost kills the buds.
