they compost really well. I usually chop mine up into 6-8" pieces just to make the process faster.

Thanks very much SG, I thought so, will do as you suggest.

Comfrey is a prolific spreader & self seeds like crazy. It can quickly get out of control. If your plants have seeds, I would bag them up for collection. The roots will sprout up again as well.

thanks B, but my comfrey plants are confined to a poor strip of soil about 8 ft x 2 ft where nothing else will grow, and can’t spread at all.
