They'll grow in just about any soil as long as itís not waterlogged; slightly acidic or neutral soil is best. When you plant
them, it's helpful to put a handful of bonemeal in the planting hole. tree
peonies revel in climates with cold, snowy winters and are hardy to zone
3. You can leave them out in the open without protection, but mulch any that are not deeply planted.
The biggest mistakes you can make when growing
peonies are over-watering and/or over-fertilizing -- they're tough little plants
and donít need to be coddled.
Hope that helps,
