While I found several posts/pages on how to grow a seedling, I'm not able to find much information on the tree 'toddler' stage. I saw another post which mentioned as long as it's summer it's best to put the seedling outside, which answers one of my questions - but presumably once the weather turns chillier I bring it back indoors? Or do I just leave it outside and protect it from frost somehow?
Also, at what point should I start trying to train it to grow straight, is that something to even worry about at this point? (It's about five/six months old, about a foot long.) Thanks for any advice, or pointer to a website, etc I may have missed.
