Agree with above members. Remove the "pot" (I find giving the entire pot a slight squeeze in your hand loosens it more) and then very carefully remove the wool. It is easy to break roots, so be careful. Create a depression in the sand and using your entire hand, gently poke the root mass into the sand and with your other hand fill in the sand around it. Make sure the crown is not buried; I usually pull the plant upwards very slowly to ensure this.
