I bought a very small tri-color beech tree last summer. I didnt want it to burn up so I potted it so I could move it indoors for winter. It grew about 6" and did really well. so I took it indoors and kept watering it all winter but not excessively. I heard they are late bloomers, how do I know if its alive? I gave a little tug on the trunk to see if it would pop right out. It didn't its still firm in the soil. I want to start moving it outdoors to climatize. But first I want to know if its Dead or Alive. How will I know?
