Have left all( over100) of my dahlias in the soil to overwinter after those that were left in during last year's very cold spell, survived. Just cut them down and mulched.
Also considering taking out, or at least cutting back to ground level, my pyracanthas, which are rampant in a mixed hedge. They can grow 4ft a year and shred me when I try to cut them back.
I appreciate this thread because it is not about what are good plants or not... they all are... but about which ones come with more "cost" than "benefit" for you.
