Clearly it's just me then.

I took a few cuttings of rosemary about 3-4 weeks ago and put them in water, changed the water every day, kept them in good light (but not direct sun or anything) but nothing happened at all! They've all gone black now and are in the compost. What did I do wrong? Any expert tips?? I'm going to have another try but don't want to repeat the same mistakes...

The single sage cutting I took about the same time rooted almost immediately and is now growing quite happily in a little pot of compost.
