Every home we have had over the many years has had a red clay soil that needed to be opened up and fortified with compost, lime, calcium, manure and peat....and lots and lots of humus
Hubby had a dump truck and would pick up loads of manure and straw washed out of semi trucks hauling livestock to our local stockyard for auction. He told the guys at work that he bought his new wife a load of "$h!t" for Christmas and that she loved it....and he was right!
We composted everything including leaves and grass we collected from curbs in town. Good compost was black gold...worth its weight in gold.
We made raised beds from many materials including cement blocks, landscape timber, used railroad ties and the end rings salvaged from a metal culvert manufacturing company. We have gardened in the empty cowlick mineral tubs, old plastic trash cans, truck tires, an old bathtub, old whiskey tubs and five gallon buckets....anything we could drill holes in for good drainage. (From experience, drill holes in the side of the tub or container about two inches up from the bottoms...not in the bottom.)
Besides a rotor tiller and a wheel barrow with a screen mesh sifter we found a cement mixer was handy back saver for mixing soil ingredients.
No soil challenge will ever deter a determined gardener!
