Fertilizing peonies is crucial for their growth and health. Starting with rich, composted soil and fertilizing in spring and fall for the first few years is recommended. After planting, peonies should only need fertilization every three years or so, and if they are truly thriving, once per season after the second year of growth is often adequate.
When selecting the best granular fertilizer for peonies, it is important to look for one that contains a slow-release formula. The best time to fertilize peonies is in early spring when new growth is about 12-16 inches tall. This timing supports the current year’s growth and ensures strong roots. For newly planted peonies, fertilize when the shoots are a few inches high to speed up growth and establishment. Established and mature peonies are best fertilized right before they begin to flower, supporting the current year’s growth, enhancing hardiness and resilience, and improving root growth.
There are two main periods when peonies should be fertilized: pre-bloom and post-bloom. In most climates, this translates to early spring and late summer (or early fall). Peonies should be fed twice a year, once after they emerge in the spring but before the flower buds become pea-sized, and again midway through the growing season to build strong roots before winter comes.
The best time to fertilize peonies is early spring when new growth begins to emerge. A second round of feeding can be applied after the peonies have bloomed, after deadheading them in early summer, and before the leafy shoots commence growth in early spring and again right after flowering season has run its course.
