Dear Bonavenyure; Yes. Did you break down the fiber pot in any way? If this is not done the root growth can be inhibited. In theory they are supposed to break down but this is not always the case. A 4 inch pot is far too small for this very large and very fast grower. As it is still July, I would plant it in an sunny location and keep it moist. It might well grow away being happy to be released from its prison. Cheers, John E.
