John,,when you planted it did you check the root system? I think yours was potbound.
Dig it up, soak the rootball in a bucket of water for 30 minutes or so then loosen the roots pulling them away from the rootball.
when you replant mix in dried mamure, pelleted chicken manure etc., and water well. Water again a while later and then mulch
