Tony Murrell, from the Radio Live Garden Show, called us recently to have a chat about trouble-shooting peonies. As the topics covered were very similar to the ones we often field at the Farmers Market, we decided we should put them up online for home gardeners who want to find out a bit more about these heirloom perennials


Peony Troubleshooting

Choosing the best varieties: Classic French varieties are often the most reliable. Don't choose by colour alone, but look also for disease-resistance, strong stems & vigorous growth habit

Disease control: In Spring, remove any buds & flowers which have botrytis, plus any stems with collar rot. Remove all stems in Autumn, once they've died down

Drainage: They do not thrive on heavy, poor-draining soil. They'll survive but they will never reach their full potential

Growth cycle: All flower & leaf growth occurs in Spring; in Summer the plants are semi-dormant so keep them dry; root growth occurs in Autumn as the tops die down

Dividing: Lift in April/May, selecting only the youngest roots with an eye attached. Large, old root masses often will not re-establish well

Planting: The best time for this is also April/May, ensuring maximum root regrowth & quicker establishment, a period of up to three years

How long before they flower? Peonies can take a while to get settled in, often not flowering for the first couple of years while they form a new root mass

And frosts? They will not flower unless they get a few good frostings each Winter. Dumping ice over them periodically is no substitute for this

and finally, some cutflower advice...

Minimum chiller time equals Maximum vase life: Buy your peony cutflowers from a trusted supplier, who can guarantee they have been recently picked & not held for too long in a chiller
