If you decide not to cut back your peonies, there are a few things that can happen. Firstly, the old foliage will remain on the plant throughout the winter and into the spring. This can make your peonies look unsightly, as the leaves may become brown and wilted. However, despite the lack of pruning, the peonies should still flower the following year.
It is important to note that by not cutting back the peonies, you increase the chances of any old fungal issues being transferred to the new growth in the spring. This can be a potential problem, as fungal diseases can stunt the growth and overall health of the plant. Therefore, it is important to keep an eye out for any signs of disease or infection and take appropriate measures to prevent their spread.
In my personal experience, I have seen cases where peonies were not pruned and the old foliage remained on the plant. While the flowers did bloom the following year, the overall appearance of the peonies was not as visually appealing due to the presence of wilted leaves. Additionally, in some instances, fungal diseases did affect the new growth, causing damage to the plant.
To summarize, if you choose not to cut back your peonies, the old foliage will remain on the plant and may become unsightly. However, they should still flower the following year. It is important to be aware of the potential risk of fungal diseases and take appropriate measures to prevent their spread. Regular monitoring and proper care can help maintain the health and appearance of your peonies.
