developing soil

We moved to central TX, a beautiful area but soils are thin. Most prominent feature is exposed limestone & caliche--a calcium carbonate formed from rainwater percolating through limestone.

Whoa! It's like the garden of Eden! What rose wouldn't die to live here?

Sometimes caliche is found as concrete like deposits just under the surface:

So planting here pretty much necessitates building on top. sometimes you can pick-axe through the caliche to form a hole, but this can result in a plant reacting like it's planted in a concrete pot--which it almost is. If you dig a hole, it has to be a big roomy one. Sometimes you can dig through a caliche deposit but we're finding that once we hit it, we can't dig through.

Here's what we do: plant a tree in a wide hole, backfill with good soil & continually add mulch & organic material.
