Upcoming of the Peonies in Early Spring
When the first Peonies show up in February / March, the use of wind fences can be most helpful to protect the still vulnerable peony plants. The fences are usually placed from the east to west to keep the cold northern wind out.
No gates are placed from south to north because that allows the wind to keep the plants dry and prevent the spread of Botrytis. When the plants are still small and vulnerable to diseases, copper sulphate can be used to ensure a firm and healthy plant. Several fungicides can be used to protect the plants against Botrytis (preventive).
