It might just be my imagination, but this early June is one of the first times that that I can remember the garden looking so nice, so early.
I still have some spots to fill with annuals and I was away for the last 10 days of May and essentially abandoned the garden. However, I did spent a day weeding and cleaning up upon my return. Being retired may also have something to do with it - more time to maintain the garden = more time to enjoy it.
