Dividing peonies isn’t always necessary, but it can be beneficial if your plants are overcrowded or blooming less profusely. The best time to divide peonies is in the fall, after the foliage has died back. Carefully dig up the plant and, using a sharp knife, divide the root ball into sections, each with at least 3 to 5 buds. Replant the divisions at the same depth as before and water them thoroughly to encourage establishment.

Preparing your peonies for winter is essential to protect them from harsh weather. After trimming the foliage in the fall, apply a layer of mulch to insulate the roots and protect them from frost. In colder climates, consider covering the plants with breathable fabric or burlap for added protection. Avoid plastic, as it can trap moisture and promote rot.

Testing your soil after your peonies have bloomed can provide valuable information about its nutrient content and pH. Use a soil test kit to determine if amendments are needed. Peonies prefer slightly acidic to neutral soil, with a pH between 6 and 7. If your soil is too acidic, consider adding lime to raise the pH. Conversely, if it’s too alkaline, sulfur can help lower it. Adjusting the soil’s nutrient balance can improve plant health and flowering.

Planning next season’s peony blooms involves evaluating the current year’s performance and making adjustments as needed. Consider factors such as flower size, color, and health. If some varieties have performed better than others, you might consider propagating them or trying new varieties that complement your garden. Keeping a garden journal to record your observations and any changes you make can be invaluable for planning future plantings and ensuring beautiful peony blooms year after year.
