cheapskate fruit tree planting

[MarkP]

I'm very intrigued. I have considered planting in mounds as well, large mounds. Digging in the ground is so hard and only gets you a foot or two at the most unless you use heavy machinery and also manage to break through a lava layer to soil underneath, otherwise you only get the benefit of the hole you dug. Just seems like more bang for the buck. Julie, where did you get your soil?
