Hello All,
About 3 years ago I planted a peony garden - 12 plants. Most are doubling each year, while a couple look like they may not make it another year - but that's a story for another day.

The garden was placed in a new raised bed part of the yard, filled with loose garden bed mix. Each peony was circled with a barrier. The dirt has since settled, and I've added more compost / garden mix over the years, being careful to not add dirt to the peonies for fear I'd inhibit their blooming.

The peonies now sit so much lower than the surrounding area. I'd really like to raise the dirt level without lifting the plant or smothering it. If I added a little bit each year, say an inch, might the plant acclimate?

Thanks for your advice. (I forget my zone - Portland, Oregon.)
