How do you replenish your beds with existing perennials?
I usually did not have any returning perennials in my little garden spot. Now that I do. How do I recondition the soil? My soil looks terrible. But, If I start double digging Alfafa and bone meal; I know I will damage or uproot my new perennials. I've got lots of Penstomen and Campunula's.
How do I work around this?
