I need your help and ideas for shade garden
First.......I believe I'm in zone 4. I'm in southeastern Wisconsin, near Lake Michigan. Would appreciate knowing my exact zone.
Next, I'm in the process of creating a shade garden located under numerous pine trees. Little to no sun. Would like more than just hostas and ferns. Any ideas? And of course when to plant, (spring, fall?) Do I need to amend soil, or leave alone? Thanks for your help in advance.
