🌱 Itoh/Intersectional Peony: Growing Guide
Itoh peonies bring the charm of herbaceous peonies with the vigor of tree varieties. Expect reliable blooms after 2–3 years:
• Soil & pH: Prefers neutral to slightly acidic soil (pH 6.5–7.0); enrich with compost or blood & bone at planting
• Planting Depth & Spacing: Bury buds 3–5 cm deep; space plants about 1 m apart
• Exposure: Shelter in full sun; part shade in hotter regions
• Watering: Keep soil evenly moist during warm months; water-wise once established
• Fertilising: Use balanced fertiliser in spring and again after bloom
• Winter Care: May not fully die back; allow frosts but skip heavy mulch
• Pruning: Cut stems to ~10 cm after autumn leaf fall to prevent disease
• Division: Divide only after 5–7 years, during dormancy; replant quickly to maintain vigor
• Container Adaptability: Yes, in large pots with winter chill and nutrient-rich soil
