Greenhouse Growing Instructions:

Peonies prefer to be grown cool (55-60° F). Keep evenly moist allowing to dry slightly between deep watering. Provide good air circulation, keeping leaves dry to avoid disease. Over fertilization will inhibit flowering. Generally finish in 8-10 weeks based on growing conditions. Use plant stakes if necessary.

Transplanting Instructions:

Plant in well draining soil in container large enough to accommodate the bare root, can trim lower roots if necessary. Place root so eyes are 1-2" below the soil surface after being watered in. Apply a broad spectrum fungicide according to directions to avoid crown and root rot.

Homeowner Planting and Maintenance Tips:

Established roots are easy to grow in moist, well-drained soil in full sun. Once established, peonies are as hardy and dependable as oaks, creating a fantastic season of bloom in your yard year after year.
