G'day Guys,
I just found this thread and a bloody good read it is. Thank you.
Some thoughts on the raised bed type garden, from another, normally very hot and usually dry climate.
I was working in Camooweal. (Go to
http://maps.google.com.au/ and type in Camooweal.) in the far north west of my state a number of years ago. This is black soil country, similar to the way Rons describes his soil in Texas. This is at best, semi arid land and during the summer, the temps get well in excess of 100f and stay that way pretty much the entire time between September and about April. No vegetables will gow in the ground there in those conditions.
When I was there, I befriended the local butcher, a part Chinese/part aboriginal man (we used to call them black Chinese back then) who not only butchered his own cattle for his butcher shop but also ran a very successful small market garden. His ideas and his methods were revolutionary in that area at the time and he suppled a lot of fresh produce to an area that had to ship such items in from the east coast, over a thousand miles away.
His garden beds were in cut off water tanks. They were cut to about 2 feet high and then filled with soil, compost, lawn clippings and pretty much anything that would assist to break down the clay like black dirt into workable soil. When he killed a beast (cow), he collected the blood and he also ground down the bones and other offal and mixed the whole lot into his beds.
When his seedlings had shot, he liberally mulched to help protect the soil from the heat from the sun and to reduce water evaporation. We do this here in Aus as a mattor of course now. What he did that was so different was that he had supported chicken wire about 4 feet over the time of his garden beds on which he put hessian bags that he kept wet. This kept the soil cool and moist constantly and he grew the best lettuce and tomatoes I had ever seen in county that a lizard nearly has to bring a cut lunch and a water bag just to survive.
Mulching is a very good thing. it not only conserves precious water, it also helps to control weeds and as the mulch breaks down, it enriches the soil. nearly all of my gardens are "No Dig" gardens in that I lay old news paper on the ground and cover liberally with mulch and keep it damp. As the mulch breaks down, i had more mulch and so on for about a year and then it is ready tyo plant.
Too easy. :mrgreen:
