Sorry I missed this, yesterday!
Wood Ash: Is best added to your compost pile. However, directly on the garden, the application should be LIGHT (don’t be piling an inch or two on the soil) and is full of lime and potassium, so plant accordingly.
It’s a good slug deterrent, and good for any acid-loving plants like blueberries and azaleas and evergreens.
Here’s the skinny from UW Hort:

Thanks good article. I think the garden has enough but we have a nice big rhododendron, and red raspberries that could probably use some. It does look like I will be buying some soil (Ugh) to have in a couple of big pots for potatoes and carrots. I really want some nice carrots this year.
