<br>The ground in my area is like clay & sand. I have been digging approx. a 1 1/2ft.sq. x10-12in. deep hole at a time, putting leaves, veg. & grass clipping by layers. Will this get the soil rich enough to get a garden started?
You introduce dead vegetative matter into the soil to enhance the humus content in the growing medium. Humus (decaying plant matter) directly supplies nutrient to growing plants, and enhances the nutrient holding capacity of the soil.<p>You need a good decay process to produce the humus you want. Decay is done by the soil microbes, millions of bacteria & fungi. Mix your leaves & grass into the soil, as with a tiller, to speed the decay process. Tilling in 3" to 6" of leaves right now in the garden area would be beneficial in our area. Gardeners here will always till leaves in at least one every year.<p>Your state extension service would be your best place for information about your specific area. They can usually be found on the web site of your land grant university.<p>----------<br>Jim<br>North central Indiana<br>
