Q.Can I cut Poppy plants back
Can I cut Poppy plants back after deadheading? My Poppy bed is very unruly and messy. Will it hurt or kill them to cut them back?

I have a friend who trims them back right after they are done blooming. She also digs them up at that time and will move them or pass them on to a friend as her bed is full and crowded. This does not seem to effect the blooming the following year in any negative manner.
Some suggest that waiting for the leaves to die off naturally is a better way.
