Tonight, after I planted the juniper, the piles of extra rocks sitting around the yard were suddenly so annoying in their messiness that I spent an hour or so starting to pile them into a dry-laid wall, as maundered about below. For a snap decision this is working out gloriously: it's gotten rid of about half the rock piles so far, and it looks fantastic. There are all kinds of nooks and crannies in it, which I may try to stuff with plants, but which will no doubt also shelter snakes and toads and all kinds of good garden critters. Also, I hear that you can paint rocks with some sort of yogurt solution to encourage moss - will have to double check that Fine Gardening article again.
How solidly this wall is constructed is anyone's guess, especially since I remember hearing that a dry-laid wall actually takes considerable skill to build, and I have none such (as the blog title notes, just enthusiasm). Well, if it falls over on the hydrangeas, no loss there, right?
As mentioned, I would looooooove to have a gorgeous copper fountain in front of this wall, where it would make a stunning centerpiece for the whole yard. The trick there is that the fountains I have my eye on require a power source, which would involve burying a line in conduit all the way across the yard from the house - a.k.a. total, abject pain in the ass. I'll have to ask if there's some way to substitute a solar or battery powered pump.
