Generally fertilizer or compost can be added to bottom of a planting hole, taking care to cover that will soil. You do not want the roots to touch the compost.
Direct contact can burn the plants.
You can then reapply a light fertilizer when the plants are actively growing in the spring.
To avoid fertilizer burn you should make sure that the fertilizer does not come in contact with the Peony crown or within 6 inches of leaves or stems.
After applying fertilizer you should water to encourage the fertilizer to mix with the soil.
To know accurately what fertilizer is needed, you should have a soil test. A balanced 5-5-5 or 10-10-10 is a good choice. Avoid high nitrogen as this will leave you with lots of leaves and no flowers.
Water out the plants to try to move the fertilizer away from the plants.
Depending on how severe the damage is, they may recover over some time.
