Tips for planting success
Plant in a sunny spot. Tree peonies are happy in most soils, so long as they’re not waterlogged or very acidic.
Ensure the grafting point is buried 6in (15cm) below the soil’s surface, and remove any suckers from the herbaceous rootstock at ground level.
For container growing, use a pot at least 1ft (30cm) in diameter, filled with John Innes No3 compost. Feed in spring with a slow-release rose fertiliser.
Don’t overwater – especially if your tree peony is in a pot.
Orange/pink-coloured leaves can develop due to iron deficiency. Using a seaweed and sequestered iron liquid feed will correct this.
Grafting points need to be buried 6in (15cm) deep
