You can put those in and they'll help. I think the reason you hear more about coffee grounds is because they make up more bulk than tea bags do.

oh yes, do put them in the compost. We compost ours, tags, staples and all. Or if you grow roses, put them directly in the bed, they'll love it.

If you put tea bags on roses should you take them out of bags and sprinkle out the tea?

Just throw them on the bed. Kick some mulch over them if you don't like the garbage-look :)

The bags break down along with the tea leaves.

They actually have more nitrogen in them than coffee grounds. I'm thankful because I drink tea, not coffee anyway!

I put tea bags in all the time - I don't drink coffee, no-one does in our house. I've heard the bags themselves can be quite slow to break down, so I give each bag a quick tug to make a tear to help it along.
