So I'm growing Lasagna!! No not really. This is just a name given to starting a new flower or garden bed with a layer of cardboard, to kill the grass and suppress weeds. Then layering mulch, dirt, and compost on top of it. As the materials decompose, the turn into rich top soil. The decomposition also brings in creepy crawlies to "till" up the soil underneath your cardboard. Very little energy input + reclaiming potential mulch from the landfill = cheap and easy way to establish a new bed.
So for this area along our fence, I pilled up about 2' of leaves from this last fall on top of the cardboard. Then added a 2" layer of the heavy, red clay we call soil down here. This is not technically, a well constructed lasagna garden, but I'm interested to see how it goes.
This is an east facing fence. I'm hoping to grow amaranth and sunflowers along the back, strawberries in the front, and then assorted herbs and artichokes in the middle.
