Sheet Mulching

Sheet mulching is probably the best way to build the organic matter and microorganisms in the soil. By composting in place you are allowing all the by-products of composting to actually be utilized by the plants you are trying to benefit.  Every time you turn a compost pile or dig your compost to bring it to the garden you are killing millions of organisms simply by exposing them to air and sunshine.  Also there are colonies of fungi and bacteria that are busily creating a network of communication and chemistry all beneficial to our plants.  So composting in place is preferred, also called sheet composting or sheet mulching.


There as many different techniques for sheet mulching.  Some basic concepts should be kept in mind such as, just like building a compost pile you want about equal amounts of brown carbon source and green nitrogen sources (manure being a nitrogen source though not green), watering all the layers well and cut down the vegetation on the site of your sheet mulching.

Sheet mulching can be as easy as placing layer of cardboard down followed by a foot of leaves on top or as as extravagant as a 16 layer cake.  Some good materials for sheet mulching starting with the green or nitrogen rich materials:

                                           grass clippings



                                           fresh weeds

                                           waste produce

                                           blood meal



For carbon rich materials use:




                                           dried leaves

                                           wood shavings or chips


Layers of compost are also used to introduce micro and macro organisms into the pile.

#1  Set Out Your Plants

Take some time to understand how big you plants are going to get and set them in place in their pots to visualize the arrangement. Create a map so you can recreate this arrangement once your sheet mulching is complete.
