Thanks, Ginda.

None of the theories - pathogens, shallow soil, contaminants, nutrient
depletion, seem flawless guesses right now. I've dug fairly deep, and have
made areas of the soil humusy; a container that deep, watered as much as I
water and planted as thickly, would produce plants, for instance; yes, I had
wondered what pathogens there might be that would have killed so many
things; the herbs live, some thrive, but strawberries and nightshade family
plants get hit hard. Now, they're susceptible things, so, maybe.

I hope I haven't sounded dismissive of anything - I've been getting great
suggestions. Thanks, again.

I doubt it's pathogens, because most pathogens are somewhat
selective, and will kill some plants, but not all plants. I've sen
what you describe happen in two circumstances:

1) A friend had some patches of her yard where nothing would grow.
After her son was diagnosed with lead poisoning, they got those
patches tested and discovered they were phenominlly high in lead, due
to a prior resident having sandblasted 100 years of lead paint off
the house. They had the worst of it taken away (at exorbitant cost,
since it was a hazardous waste) and covered the rest with 4-6 inches
of mulch. Stuff grows fine in what they have left.

2) I have some patches in the backyard that die every year during
the heat of the summer. Stuff (that I plant, or weeds if I don't)
grows fine during the spring and fall, but when the weather gets die
everything dies. I have bedrock not far beneath the soil, and I
believe those are the patches where the rock comes closest to the
soil and has the fewest fissures.

zone 6, eastern Mass, where everything sits on granite if you go down
far enough.
