Re: Health check please!
Ideally you'd have a natural mulch instead of rocks. You didn't mention fertilizing. Have you? Even Miracle Gro would give them all a boost; they look hungry to me. I'm fortunate to have mine in a kind of swamp with real dirt so haven't fed her much but I do dump coffee grounds around her. I've just found a source for rotten bananas and plan to make smoothies for her. (Not sure if that would stain your gravel but your plants would love that extra K.)
