Chinese peony 'Sarah Bernhardt' in November: monthly care

Paeonia lactiflora 'Sarah Bernhardt' thrives in full sun or partial shade, though flowering is most abundant with at least six hours of direct sunlight daily. Choose a sheltered spot where the plant can remain undisturbed for years—peonies resent being moved once established. The soil should be rich, moisture-retentive loam or clay that drains reasonably well; waterlogged conditions in winter will rot the crown. Prepare the planting area by digging a hole roughly 40 cm wide and 40 cm deep. Work in plenty of well-rotted manure or garden compost, mixing it thoroughly into the base and sides of the hole. If your soil is heavy clay, incorporate some horticultural grit to improve drainage. Plant bare-root peonies in September, October or November while the plant is dormant. This autumn planting window is critical: it allows the roots to establish before winter and ensures good flowering the following year. Position the crown so that the dormant buds (eyes) sit no more than 2–3 cm below the soil surface. Planting too deeply is the most common reason peonies fail to flower. Space plants 80 cm apart to allow for their mature spread of 70–90 cm. Backfill with the improved soil, firm gently with your hands, and water in thoroughly even if the ground is already damp. Apply a 5 cm layer of well-rotted compost or leaf mould around—but not over—the crown. Avoid further disturbance, and be patient: 'Sarah Bernhardt' may take two or three seasons to flower well as it settles in.

Paeonia lactiflora 'Sarah Bernhardt' requires minimal pruning, but a proper autumn tidy-up is essential for plant health. In October or November, once the foliage has been blackened by the first hard frosts, cut all stems down to ground level. Use clean, sharp secateurs and remove every piece of top growth. This autumn cut-back serves two purposes: it prevents the overwintering of fungal diseases such as peony wilt (Botrytis paeoniae), and it tidies the border as the plant enters full dormancy. Do not be tempted to cut back earlier while the leaves are still green. The foliage continues to photosynthesise well into autumn, feeding the crown and building energy reserves for next year's flowers. Even yellowing or tatty leaves should be left until October. Gather up and dispose of all pruned material—do not compost it if you've seen any signs of disease during the growing season, as botrytis spores can survive. During the flowering period in late spring and early summer, deadhead spent blooms by cutting the stem just above the first set of strong leaves. This prevents the plant wasting energy on seed production and keeps the clump looking tidy, though it won't encourage a second flush. If the heavy, double pink flowers of 'Sarah Bernhardt' flop in rain, you may need to stake the plant in April before buds form; use grow-through supports or a ring of canes and string. Beyond this seasonal cut-back and deadheading, herbaceous peonies need no shaping or renovation pruning.
