The late, great Christopher Lloyd wrote in The Adventurous Gardener “…by exercising a little vision you will realize that [your] tree has a future, perhaps even a great one…..it may be more important one day than yourself.” I’m grateful to say this won’t be true of the huge but now dead and gone Norway maple (Acer platanoides) that lasted about 60 years in our backyard. It spent its last 30 years—the time we lived with it—besetting me with its grasping, thirsty roots, which kept coming to the surface no matter how much compost I piled over the soil. Its falling keys sprouted into hundreds of baby Norways every spring, causing endless backaches as we pulled them out.
