A garden center does not sell pre-bonsai. What you have purchased are nursery plants.
Thanks for response Auk!
Sorry for my misusage of the term, I am quite new to Bonsai. My only experience is with a bird plum which I purchased 9 months ago. But ofcourse one was not enough and I decided to improve my bonsai collection as fast as possible. But I think because of the season the best way for it to buy an already established bonsai. Otherwise I have to wait till spring for any plant I purchase right now. Right? Is there any advantage of buying nursery plants right now? I mean can I do anything to prepare them for early spring( when I can start working with them) or waiting till early spring and then buying them makes no difference?
Again thanks for the links, I will dig deeply into this site for sure!
