What to do with soil in containers after harvest?
I live in the Portland, Oregon area. I grew potatoes in three potato grow bags this year and just harvested them this past weekend. I don't know what to do with the soil though, can you use it again next year to grow potatoes in or what do you do with it? Would the soil get compacted, hard, or loss its nutrients? I have this trouble with my raised beds.
Thank you for any advice!
