How do they look as they die off for the year? Mine are Ok so far but it's only been two weeks or so. Can I leave them outside overwinter or do they need to be taken somewhere where they won't be covered in snow and subjected to the MN winters (I'm in zone 4)?
Is Pine bark mulch Ok to use? Everyone talks about pine needles but I saw a big bag of pine bark ground into 1/2" pieces for a good price and was wondering if that would accomplish the same as bark and pine needles?
