Can the pot be cut? Do you have a lid that would fit over it?You cloud make a hole in that lid,cut to the center and widen an opening for the stem.It will fit around the plant like a collar.Tape the cut with duct tape for stability. Wait until the soil is slightly dry and pulling away from the pot for easier removal.Get a helper if you can,or a waist high table barring that.You and the helper do this: The helper turns the pot over while you support the lid with your arms.The dirt will rest on the lid,the plant will be upside down.That way you don't pull and tug at the dirt and cause it to crumble or damage roots.To plant, flip the plant and dirt into a prepared hole,remove the lid, and plant as usual. To do it by yourself, take the plant over to a waist high table, wrap one arm around the pot,and support the lid with your other hand.Carefully turn the pot over so the lid rests partially on the table,to the stem of the plant.This frees your other hand to gently shake and tap the container.When the plug of dirt begins to come out,support the lid again with your hand, and pull the bucket up and off.Toss it aside for now,and support the lid with your arms and hands,slide the weight slowly off of the table, carry it to the hole, flip and plant.Hope that helped.
