I would encourage you to join a bonsai club and take some classes. Also, do your research before you buy. Make sure you can provide the care needed / required to grow the trees you are thinking of purchasing. Then shop and buy from a local bonsai grower. Do not buy from a mall kiosk or from a roadside stand. Trees that come from a local grower, in most cases, have already acclimated to the particular climate / area where you live. And most importantly, remember bonsai are trees meant to be grown outdoors, and not to be confused with "house plants". Good luck. Rudy
