hey Sam
Same problem here in Maryland. Does your garage have windows? If so, i think you should move your plant close to the window and give it another drink. Daytime temps are reaching high 50's, even low 60's and evening temps are just freezing. The plants in our garages I think are just waking up to these early spring temps, and given our lack of any real winter so far, spring shouldn't be too far away.
I have some plants pushing buds and leaves in my cold garage, cold sun room, and warmer sun room. I guess we just have to go with what mother nature brings us.
