Growing beauteous peonies in outdoor planters
Peonies, beloved by gardeners for their stunning color and lush foliage, can actually thrive in containers! This opens up a whole new world of possibilities for those of us with limited space. This article will give you all the tips and tricks for growing these gorgeous blooms in planters, ensuring they thrive year after year.
Choosing the right planter
The first step in successfully growing peonies in planters is choosing the right container. Peonies have deep root systems, so you'll need a planter that is at least 18 inches deep and equally wide. Drainage is key. Make sure the planter has plenty of drainage holes to avoid waterlogged soil, which can cause root rot.
Selecting soil and fertilizer
Peonies love well-draining soil with a neutral pH level. A blend of two-thirds high-quality potting soil and one-third compost creates the ideal nutrient-rich environment for them to thrive. Incorporating a slow-release fertilizer at planting time ensures your peony has the support it needs to grow strong and healthy all season long. Just keep in mind, peonies don't like super rich soil or excess fertilizer, so don't go overboard!
Planting your peony
Plant peony tubers in containers in early fall. This gives them time to establish before winter sets in. Position the tuber in the pot so its eyes (budding points) are no more than two inches below the soil surface. If you plant them too deep, they might not bloom. After planting, water thoroughly. Maintain consistent moisture (but avoid waterlogging) throughout the growing season for healthy growth.
Caring for your container peony
Container-grown peonies need a bit more care compared to garden-planted ones because of their limited space. Ensure you water them regularly, particularly during dry periods, as pots dry out quicker than the ground. And, offer support to your peony as it grows; stakes or a peony ring will prevent the heavy blooms from falling over.
Winter care for potted peonies
In zones three to eight, you should take steps to protect potted peonies in winter when temperatures drop below freezing. Simply move them into an unheated garage or shed. This will still allow the peonies to go dormant without the risk of the soil freezing solid. This way, they get the cold they need to bloom next season, but they're not damaged by extreme cold or big temperature changes.
