Three things have worked for me and they take patience. (or a hammer and chisel)
Surround the anemones foot with pieces of rock, redirect a powerhead at it and hope you're home when it decides to move.
Hold the rock it's on upside down out of the water so just the tentacles touch and hope you have more determination than the anemone.
Bust up the rock with the hammer and chisel, it's probably the most effective.
