UW Botanic Gardens’ Center for Urban Horticulture (3501 NE 41st Street) is having a free class called "Inexpensive Ways to Build Better Soil" tonight from 6:30-7:30pm.
The information says:
Mary Machala, Master Gardener, will show and tell easy ways to build your garden soil using found materials from your own or your neighbor’s yard (and possibly elsewhere).
We’ll have a brief primer on soil – what it is and what’s in it that you want to cultivate. We’ll digress into containers, compost, how to overwinter garden, mulch, flowers, vegetables and maybe even cover a little about pruning.
