I'm sorry if this is a stupid question but I'm very new to gardening. Yesterday I took a small branch of Cherry Blossom from the floral arrangement where I worked. I've always loved cherry blossom trees to the point of obsession- so I'm wondering if I can grow a new tree from this branch (once again. sorry if this is an idiotic question). If its possible, could you please tell this idiot beginner how? The clearer the directions the better!
