Growing perennials in raised bed
I have a raised bed that is 12ft x 4ft and 12 inches deep. I have been growing veggies in it the past 3 years. I am thinking about filling it up with perennials this fall; such as daylilies and other plants that I can divide. Do you think that the perennials would survive winter in this kind of raised bed since they will not be planted directly in the ground? Any suggestions of what kind if plants would grow well in this type of bed?
