I’m curious – why did you plant the dwarf fruit trees and the butterfly bushes together?

if you’d rather go organic to help feed your soil then compost tea is the miracle working powerhouse method

i like steve diver’s intro:

and Elaine Ingraham as world soil expert at soilweb – though much harder to decipher.

chicken tractors are a really cool.

Soil doesn’t “wear out”–it runs out of certain things; my guess is that your good garden spot needs either lime or nitrogen–I’d do a soil test and figure out which. Nitrogen fertilizer is one of the really great inventions.

I’d definitely get chickens; they are scavenging omnivores, so you can feed them all your kitchen scraps except raw eggs and raw chicken. (They’ll eat those too, but you don’t want them to learn to.) Get 4-6 chickens, and you’ll have all the excellent fresh eggs you can eat and they’ll compost everything for you.

And you should definitely grow a few strawberries.

This is the first year the peaches appear to be producing good fruit–one of the three trees has a bumper crop on it. I’m hoping that the proximity of the trees to the street and foot traffic plus the relatively slender build of the trees is enough to inhibit squirrels going for them. But I’ve seen them do exactly what you describe with other things. I gave up on corn for that reason: they’d take the ears when they were teeny, decide that they didn’t want them after all, and so leave all these itty-bitty inedible corn cobs all over the place. Bastards.
