Peonies require a balanced (1-1-1 ratio) fertilizer to enhance their growth and blooming potential. A good ratio is a 5-10-5 fertilizer, which contains 5 nitrogen, 10 phosphorus, and 10 potassium. Granular fertilizers release nutrients slowly over time, while liquid fertilizers and foliar feeding provide an immediate nutrient boost.
Homemade fertilizers like compost tea are excellent for providing a nutrient boost. The best N-P-K fertilizer for peonies is typically a high potassium fertilizer, such as a 5-10-5 ratio, or a balanced 10-10-10 fertilizer if that’s what you have on hand. Organic options like bone meal, well-rotted manure, and compost are also suitable for peonies.
Balanced, slow-release fertilizers contain equal amounts of nitrogen, phosphorus, and potassium and are a good choice for most peonies. Peonies should not be over fertilized, and bone meal is a good fertilizer to use. Commercial N-P-K fertilizers, such as 8-18-8, should be applied three or four times per year at a rate of 2-3 pounds per plant.
Peony fertilizers should be low in nitrogen and high in phosphorus and potassium. Use a fertilizer with a 5-10-10 ratio of nitrogen-phosphorus-potassium.
In summary, peonies thrive on a 5-10-10 fertilizer, which includes 5 nitrogen, 10 phosphorus, and 10 potassium. Proper fertilization can help ensure healthy growth and blooming potential for peonies. Choose the right fertilizer for your needs and avoid overfertilization.
