Expert tips
The key tip
Chinese peony only flowers well if planted deep enough (eyes 5 cm below ground) and left undisturbed for at least 3-4 years. It takes patience, but it lasts 50 years.
The common mistake
Moving it or digging it up to see why it won't flower in the second year.
The pro's trick
In late spring, before the heat kicks in, apply a light mulch (3-5 cm) to keep the soil cool without smothering the eyes.
Seasonal watch
Watch for powdery mildew from June onwards in humid climates: space out plants, improve air circulation, and intervene at the first sign.
Care
Light exposure
Position your peony in partial shade to partial sun, with at least 3 to 4 hours of direct sunlight daily for generous flowering. Avoid overly scorching south-facing exposure in Mediterranean climates. A location slightly sheltered from strong winds is preferable.
Watering
Keep the soil moist but well-drained, especially during spring growth and summer. Water regularly during dry periods, but allow the soil to dry slightly between waterings. In autumn and winter, reduce watering.
Soil
Choose rich, deep, well-structured soil, slightly alkaline to neutral. Improve the soil at planting time with quality compost or potting soil. Avoid compact, poorly drained soils that promote disease.
Fertilizing and nutrition
Apply balanced or peony-specific fertilizer in spring when growth resumes. An application of well-decomposed compost each autumn is generally sufficient to maintain soil fertility.
Pruning and maintenance
Remove withered stems at ground level in autumn or late winter. Peonies don't require drastic pruning; simply remove spent flowers to encourage next year's blooming. Leave the plant in place: it improves with age.
Diseases and pests
Watch for powdery mildew in warm, humid weather: improve air circulation at the base of the plant and avoid overhead watering. Peonies are generally quite resistant to pests. Good drainage prevents root rot.
Did you know?
The herbaceous peony has been cultivated in Asia for over 2000 years, particularly in China where it symbolizes wealth and honor. Remarkably, an established peony can live over a century and bloom faithfully each year without major intervention.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
