Here’s the deal: concrete takes time to set, usually 48 to 72 hours. I know, waiting is the worst, but it’s worth it. Once it’s dry, gently pull the tree out of the mold. If it’s being stubborn, give the mold a light tap or wiggle the wire base.
If you notice small cracks or rough edges, don’t panic. Sandpaper can smooth those out in no time.
