Again, thanks for the tips. Rick, I gave a couple dozen ferns epsom salt feedings today. One of the great things about buying an established garden is that you inherit wonderful plants. But a drawback is nothing has a care tag, so you rely in the kindness of strangers.
If only the previous owners had not planted ivy with the ferns. Who knows how many more may be buried beneath it?
I've decided to cut the ratty juniper a break (It's not quite as tall as it appears in the photo.) As I reflected on my seven years with it, I realized that it is living in a 20" wide bed. (The neighbors have a walkway on the other side of the fence.) It survived the driveway being replaced last year and the fence being replaced six years ago. It is shadowed by the houses much of the day. It will never do much, but It is a survivor.
