So who ever said repotting a large bical was difficult?
My 3' bical was in a 8" hanging pot. All I had to do was gently loosen it from the sides, then gently pull up. POP! Out came the whole thing. That is one tightly packed rootball.
I love it when you have a plant that hates root disturbance and you can repot the sucker without breaking a single one!
New pot is a 10 gallon - should hold it for a while!
