Mine are not really in a garden, but grow on the outside of my fence. At over 100 feet long it would be a lot to cut by hand , so in early Oct. I set the lawn mower on high and use it to cut them down. I have been doing this for many years without any problems. I know it sounds kind of crude but it works well. I have always fed mine in early Spring with fish or kelp fertilizer just as they start to emerge.
