Sheet Mulching

Moistening Sheet MulchMoistening Sheet MulchSheet mulching is a technique used to supress weeds, build soil nutrients, conserve water, and protect garden plants. 

The key to sheet mulching is to lay down a weed barrier such as cardboard.  The cardboard prevents light from reaching the soil and creates a barrier to plant growth.  It allows water to drain into the soil and breaks down naturally over time, avoiding many of the problems associated with plastic weed barriers.

Students collected cardboard boxes left over from a delivery of new desks, chairs and tables and spread them over the weeded areas of the garden.  Students then moistened the cardboard to help it conform to the contours of the soil before covering it with tan bark mulch.
