My hydrangea bushes in the spring have dried brown flowers at the ends of stems. Can I cut these off? Will it interfere with new blooming?
Yes, you can cut off the dried flower heads! And as the green leaves continue emerging up the stem, you can then cut back to just above the last set of green leaves (but wait on this until May to give it the most time to wake up): https://www.youtube.com/watch?v=L6LOS8orBrE.
