Planting Depth: Planting depth is absolutely critical to flowering performance. If the eyes are planted too shallow or too deep, they may not flower. This is the most common mistake that is made when planting peonies and is most often the reason that peonies fail to flower. Peonies must be planted with their eyes 1½ to 2 inches below the soil line. Plant Peonies roots in soil that has been amended with organic matter.
Light: Plant Peonies in full sun to light shade. Morning sun with light afternoon shade is ideal. Shading plants from the hot afternoon sun will help the flowers from fading.
Mulch: Newly planted fall divisions should be mulched before winter arrives. This will help prevent heaving from nature’s freeze-thaw cycle.
Fertilizer: To get your peonies off to a healthy start we recommend at planting applying an application of Espmoa Organic Bio Tone Starter Plus. The spring after they are planted, after flowering, fertilize with Espoma Organic Plant-Tone. This will give them the energy they need to recuperate from blooming and keep a healthy root system.
