The Sherwood Gardens tulip dig is Saturday, May 26th, starting at 7 AM. Get there early (with your own trowel) to dig up your own bulbs. They are about a quarter a piece and in many different (and exotic) varieties, so this is a great deal. We got most of our tulips there last year and they all bloomed this year. What you do is dig them up then wrap them in newspaper and plant them in November for next Spring.
Go early to get the best bulbs!
