Thanks for writing. It's common for hellebores to not bloom the first year after you plant them, especially if you plant them late in the season. This perennial takes its time to get established.
So without being able to see your plants, I can't say for sure, but I'm inclined to believe there's probably not a problem. Hellebores are extremely tough. While they grow best in moist, well-drained soil, they do tolerate a fair amount of drought.
Brown on the leaf edges commonly comes from cold temperature dips as the new leaves emerge, unseasonably cold temperatures during the winter, or exposure to lots of cold, drying winds.
I hope this helps. Good luck!
