So, my peonies finished blooming a couple of weeks ago, and I figured it was time to get out there and do some post-bloom care. I’m no expert, but I’ve learned a few things over the years that seem to help my plants come back stronger next year.
Deadheading the Spent Blooms
First things first, I grabbed my trusty pruning shears and went around snipping off all the faded flower heads. I made sure to cut right below the flower, but above the first set of healthy leaves. The idea is to prevent the plant from wasting energy on producing seeds. We want it to focus on storing energy in the roots for next year’s blooms, you know?

Cleaning Up the Foliage
Next, I took a look at the leaves. Some of them were starting to look a bit yellow or had some brown spots. I pulled off any that looked really bad, but I left most of the green, healthy-looking foliage alone. Those leaves are still doing their job, photosynthesizing and making food for the plant.
Fertilizing (or Not)
Now, about fertilizing. Some people say to fertilize after blooming, others say to wait until spring. I usually do a light feeding now. I’ll give them a little bit of balanced, slow-release fertilizer. I just sprinkle it around the base of the plants, being careful not to get any on the leaves, and then water it in well. I’ve found that this helps them store up extra energy for the winter, so they will show up a healthy blooming next year.
Watering
Speaking of watering, I make sure to keep an eye on the soil moisture. Peonies don’t like to be soggy, but they also don’t want to dry out completely. I stick my finger in the soil, and if it feels dry about an inch down, I give them a good watering.
Mulching (Optional)
I also put a thin layer of mulch, like shredded bark or compost, but I have read that it’s not a must do.
I spread it around the base of the plants, keeping it a few inches away from the stems.
The point to keep the soil moisture and protect the root during the winter.

Just Waiting
And that’s pretty much it! After that, it’s mostly just a waiting game. I’ll keep an eye on them, watering when needed, and maybe pulling off a few more yellowing leaves here and there. But mostly, I just let them do their thing and get ready for winter. Then, come next spring, hopefully, I’ll be rewarded with another round of beautiful blooms!
