Good Questions: Tips for Improving Gravel Garden?

Dear Apartment Therapy, My boyfriend and I moved into a new place about 7 months ago, and since then have been trying to clean up and 'make nice' what little outdoor space we have. We have a small courtyard space which has been laid with white gravel that (from what I understand) is essential for drainage. I've put a border of stones around it and started to plant some succulents (which I hope to continue to add to) but the gravel looks awful! Do you have any tips on how to clean the gravel with something safe enough that won't kill my plants (and the big Yucca tree)? A friend recommended a pressure washer...but that would throw gravel all over the place! Also, any tips for how to make the space look nice! Thanks,Heather

I would add a generous amount of new gravel on top of the old — it will freshen it up and be considerably easier than trying to clean existing gravel! Anyone else?
