The Clack County Composter Recycler program is offering a free online workshop from 7 to 8 p.m. April 24 about how to build and plant a raised-bed garden using the lasagna composting method. No tilling or turning is required and most materials are free. It doesn’t matter if your soil is clay, sand, grass or weeds, because this method goes right over the top.
