As October arrives, it’s time to focus on pruning your herbaceous peonies. These beautiful bushes should be pruned after the first frosts. You can tell it’s time to prune by observing the leaves, which will turn red and begin to bend toward the ground. By this stage, the roots will have absorbed all the necessary nutrients from the upper part of the plant.
1. When to Prune Peonies
Prune your peonies after the first frost, when the leaves show signs of turning red and wilting. At this time, the plant is preparing for the winter period, and the roots are fully nourished. Start with the early varieties, followed by the late varieties.
2. How to Prune Peonies
When pruning, cut the branches parallel to the ground, as close to the soil as possible. Avoid leaving stumps, as these can serve as entry points for infection. Leaving stumps can also reduce the frost resistance of the roots, making the plant more vulnerable to cold damage.
3. Protecting the Soil
After pruning, sprinkle the soil around the peonies with ash. This helps to enrich the soil and protect the plant. If you live in an area with very cold winters, cover the peonies with a layer of lowland peat or humus. The mulch layer should be between 7 to 10 cm thick to provide adequate protection against the cold.
4. Additional Autumn Care for Your Garden
Autumn is also a great time to prune fruit trees and shape their crowns. Proper pruning helps prevent the spread of diseases that can occur due to infected branches, ensuring healthier trees and bushes through the winter.
By following these steps, your peonies will be well-prepared to withstand the winter and come back strong in the spring.
