haha thanks! I should tell you though -- the soil is super rich in beneficial bacteria, lignin, etc. I've laid down hundreds of cubic yards worth of tree trimmer mulch (I'm getting close to 1,000 cubic yards worth) over the past 6 or so years. I took what was previously 3 inches worth of 50 / 50 mix (muck + sand) and added 6 inches of pitch black compost (9 inches in some places). The ground is covered with worm castings. The problem is that just below that 9 - 12 inches of soil is limestone rubble.
During the winter months, I generally lay down about 250 cubic yards of tree trimmer mulch (10 loads from a custom built 30 yard truck). I do it in the winter months so that the guy I pay to move the mulch doesn't pass out from the heat :-). Costs me around 2k just in hourly labor. But, my yard is the only one in the canal area where most trees thrive, so it's worth it. In retrospect, I probably should have bought a pad up in the palm beach area with better soil.. but hindsight 20/20.
(All of those potted plants that my wife used to have -- 90% are gone. I deleted about 2,500 - 5,000 containers and gave the wife a confined area :-). The yard is a lot more open from when you last saw it.)
