Robert Brennan Did you ever get an answer to your question? I'm wondering the same myself. Have you any idea? Its been a while since you asked your question i see.
If your patio is gravel, give it a good raking to straighten things out and remove debris. I refuse to recommend using a leaf blower, as the constant cacophony of them around my neighborhood is the bane of my existence, but blow if you must. For cleaner air opt for an electrical one versus gas.
pea gravel looks classic, but inviting and casual. Like the bench, the fountain and the container plants . . would add stones or pavers to make it easy to walk on with bare feet . .
