Hi Peter!I bought one of those new variety Peony plants this Spring. Awesome, huge yellow flowers. But, after the flower falls off, am I supposed to deadhead? And, do I cut to the ground in the Fall?Thanks!
Yes snip off (deadhead) the flowers when they finish to stimulate reblooming. Yes, cut then to the grown after hard freezes have killed the foliage. A light covering of evergreen boughs will help keep the soil from thawing out during winter warm spells that may occur. Resist the urge to uncover them until late March.
