Question: Can peonies be fertilized with 12-12-12 ? Also when is the best time to fertilize and how do I know how much to put around each plant? Thank you. Jeff Stanton, MI
Answer: Your 12-12-12 fertilizer is fine for peonies. In the spring, sprinkle a handful around the perimeter. Apply when the soil is moist but the plant foliage is dry. Scratch it into the soil and water. Enjoy the blooms!
