South Florida Soil Building with Mulch

This is a short overview on how to make new soil in south Florida.

This video illustrates the result of two years of fun work.  Replacing the ugly traditional grass and sugar sand with plants of all kinds and tons of mulch repeatedly.  This was a low cost, highly sustainable approach to creating good soil without buying it.


Additionally, the heat and humidity make it an ideal place to create soil quickly and efficiently with almost no expense (but lots of moving mulch into place, so free is relative).

There are a few pieces of equipment needed:

  1.  A wheelbarrow or something to move the mulch in.
  2. A strong pitchfork.IMG_20160608_151537
  3. Get a dust mask if you are sensitive to mushroom spores (if moving the mulch within the first month it’s on location).
  4. Cardboard (I get mine from behind Pier 1, they have huge boxes and I can usually get what I need in one stop.  I ask the manager once for permission and go whenever I need it.)
The overview on how to create soil for almost free:
1.  IMG_20160504_120250Acquire Mulch.  Tree trimmers are always ready to drop off a batch, so call around, find a local trimmer and give them clear instructions where to drop the mulch.  Always get much more mulch than you think you need.  You don’t need yards of if, you need truckloads of it to grow soil.  (One truck load at a time!)
2.  Put cardboard  over any weedy areas and mulch over the cardboard heavily.
 3. Put mountains of it in the walkways (within reason for safety) and anytime it gets flat, add a bit more.  Add it to plant beds to keep the weeds down, as thick as you can (use cardboard in trouble areas).  Give a little space to plants that may rot if they come into contact with the mulch, but I usually just pile it on and most of the plants seem to work well with it.
4.  Twice a year, you sweep aside the mulch in the walkways and find that dark young mucky soil hiding underneath.  Use a flat shovel and shear off the top soil and put it in the beds (sometimes you may need to break it up).  Don’t go too deep,  just the top dark layer.  Put the half cooked mulch back in the walkway and then what?  Add more fresh mulch.  This is essentially replacing the need for peat, which was something I was unwilling to buy because it is a non-renewable resource.
This is me in my mulching outfit. Glasses were because I was chipping too, but you get the idea. :)

One of the things I’ve found is that timing is important.  If you can move a freshly chipped tree onto its cooking location (where it will remain for months) it will cook that much faster because it is moist and quickly form the mycelium that creates the heat and soil we are after.

I’m adding 3-6 inches of rich topsoil every year with this process for my whole yard.

One more optional step:

You can take it a step further….  I added a wood deck over my mulch so that it is out of the sun and will cook faster.  (It also makes my wife happy since she doesn’t have to wobble through as much mulch when working in the garden.)

It is a bit more work, but the wood was free and sitting around.  The process is the same, except you build your mulch up and then put a floating deck over the top.  Once a year I lift one set of boards, grab the soil and replace the deck on some heaping fresh mulch, then I repeat for the next set of boards.  I will usually spray the underside of the wood with Neem Oil to help keep it from rotting away with the mulch.

 The REAL magic is sooo tiny!

The rock-star in all this is the bacteria and mushrooms that go to work on the mulch so quickly.  They may be small, but they are mighty and with a little bit of help they can do the work so much faster than you would expect.
