How to Plant Peonies
Peony roots are available to purchase at box stores, nurseries and online catalogs. The key importance when planting these roots are:
Find a sunny location with 8 hours or direct light.
Prepare the soil in the planting location first, adding compost/shredded leaves, etc. into the soil to a depth of 12 inches.
You can add a couple tablespoons of sulfur in the planting bed, and mix in with the soil. DO NOT put sulfur directly in the bottom of the planting hole.
Water the mixed soil so it can resettle before planting.
Peonies needs to be planting shallow. It is very easy to plant them too deep, which leads to no blooms or flat-out failure.
Very lightly cover with mulch on the top with mulch, no more than an inch deep.
