I've been trying to grow hellebores in Chicago (Zone 6a) for a few years, and I'm at my wits' end! We planted them in a spot that gets about half shade and half sun, and they bloomed beautifully their first spring after planting. But ever since, things have gone downhill. Half of them died after the second year, and those that survived hardly flowered. We haven't changed how we care for them, and other plants in the same area are doing fine.
We bought more hellebores last spring, including hardier varieties, and even moved some to sunnier spots. They looked fine over the summer but didn't grow much. After following some advice to trim back most leaves last fall, it looks like only one of them might bloom this year. I'm concerned I might be dealing with a possible disease or caring for them incorrectly. What are the best practices for taking care of hellebores throughout the seasons? Is it better to leave their foliage in winter or cut it back? Any suggestions would be greatly appreciated!

I get your frustration! Hellebores can be tricky. It's great that you mulch in the fall, but trimming back leaves is also crucial—just be sure to leave the new growth. You might want to keep them more sheltered during cold snaps.
If you're still having trouble, look out for signs of root rot or pests—especially with the mushy buds you mentioned. It's also vital to ensure they’re not getting trampled again by recent landscaping work. Maybe try planting them with a bit more space next time. Fingers crossed for you!
Hey there! It sounds like you've been doing a lot right, but hellebores can be finicky. First off, have you checked the soil conditions? Hellebores prefer well-drained soil with good moisture retention. It might help to test the soil for acidity, too, especially since you've got that evergreen nearby which can affect pH.
Also, don't forget that hellebores can be sensitive to over-fertilization. You mentioned using slow-release fertilizer—maybe try cutting back or switching to a balanced organic option? And while they don't need a ton of care, mulching can indeed help with winter protection. Good luck!
I totally agree with you on the soil testing! It can make a huge difference. And yeah, sometimes less is more when it comes to fertilizer!
Thanks for the tips! I didn’t think about pests or root rot—I'll definitely check that out.
