I know they did it. When I wasn't looking. Squirrels. With their clever little paws, they dug up my tulip bulbs and moved them to all sorts of random locations. Like in the lawn. Or under the forsythia bush.
Last year, several stunning red tulips appeared, scattershot, in the long narrow flowerbed lining the driveway and in a couple crowded clumps under the burning bush. I didn't plant these tulips. They just came up on their own. I'm guessing the thieving squirrels uprooted them from someone else's unsuspecting flower bed and transplanted them to mine.
This year, all that's left of those red tulips are the ones next to the burning bush. Not a single red tulip dots the rest of the flowerbed. Hope the squirrels returned them to their rightful owners.
