As one of our readers commented, my terraforming project created tiny chinampas.  All winter, the rye I sowed on the raised parts of the beds thrived despite the soggy aisles, and come spring, wildlife moved into the little ponds between the beds.  I found two baby snapping turtles hanging out in the shallow water this weekend, and plenty of tadpoles are escaping their eggs to join in the fun.

As long-time readers will realize, we struggle to deal with the wet ground in certain parts of our garden, so seeing how well these little chinampas do has been an eye-opening experience.  I decided to go ahead and dig the back garden into similar raised beds to ensure that this year's tomatoes don't suffer from wet feet.

You'll know if your soil is wet enough to need small-scale chinampas because rushes and sedges will be growing in the mown aisles along with grass.  To confirm that the groundwater is too high for the soil to be planted into as-is, dig around a clump of earth, then grab the grass on top as if lifting the clump up by its hair.  If the soil is well-drained, the whole clump will stay together since roots go straight down into the subsoil.  If the soil is waterlogged, the top will peel off since the plant roots stayed in the inch or two of soil above the water.

I dug one long chinampa Monday, which is about all my wrists can take before they start to complain.  I mostly tried to place the sod grass-side down so it will rot quickly, but I wasn't all that particular about it, knowing that I can always lay down some cardboard over top before transplanting in my tomato sets.

Of course, the down-side of turning the garden into chinampas is that I may be walking through an inch or two of water in the aisles if the summer is wet.  But better my feet get wet than my tomatoes complain!  Plus, if the aisles turn into ponds, they won't have to be mowed, right?
