The Lasagna Gardening Method is a gardening style where you layer organic materials and do not till or dig and give the bed time to break down into fluffy, rich soil full of nutrients and less weeds.
A lasagna garden bed is essentially a lot of layers: thick brown materials, thinner green materials, soil, and straw, with a bottom of cardboard or newspapers to keep the weeds from growing.
I would recommend putting wood chips down on walkways between your beds to help keep weeds away, the walkways from becoming compacted and an additional nutrient source to add to the top of your bed come spring when you add fresh mulch to the walkways.
It’s best time to start your lasagna beds is in the fall when leaves and other dried brown materials are plentiful, but you can start them anytime you want.
