I would keep the Azalia bonsai in the greenhouse till March then start acclimatising it to outside with a view of keeping it outside permanently.

Crab apple are really hardy - I would take it outside asap.

thanks kildermorie its been outside along time maybe its better there as you say cheers

i have a realy good expert bonsai grower and any trees that naturaly are from a temperate zone are outside period . he just has a couple of trees indoors that are from hot countries . i hope this helps .

thanks noseypotter i will place the crab apple outdoors in a safe place ,cheers
