Ok, I'm not your average skilled gardener. Soil testing and ph numbers and scientifically portioned fertilizer and mulches just fry my brain, so I pretty much do what comes to mind and then wait and see what happens. Let me tell you what happens I just dug up a 50'x4' strip of ground to mix in a bunch of grass clippings which happened my way (one of the ding-dong ways to improve soil). This is the area I dumped a lot of rabbit manure and straw on last year, along with kitchen compostables and chicken coop cleanings and leaves and such. Well, the ground is nice and loose as deep as I dug, and there's about 4 worms in every shovelful of dirt! Just the same as my small flower bed, except I took more care with that one, mixing things in nicely and whatnot. Seems like mixing things in nicely isn't necessary to turn compacted high desert dirt into rich soil, at least not when a wet, cold winter helps the process. This morning, I am a HAPPY camper, LOL! The previous owner of the property killed just about every living thing in the ground just before I bought it. Now, after a decade of trying to improve this dirt without having any money to spend on it, it's finally happening. And do you know that I wouldn't ever have thought of getting into rabbits if it hadn't been for my hungry snakes? Windfall pet snakes = rabbits = manure = good dirt for planting. Don't let anybody tell you that there isn't a gracious God who looks out for his ding-dong creations, LOL!
