Ummm, I would not suggest repotting it. I have a few Dawn redwoods in small pots and they are about an inch high and they're doing great. I don't think you need to worry about transplanting/repotting yet. =)

paulahuys,

I have a feeling that apple trees do not grow into the same apple trees from a seed. They grow the same but the fruit is not the same as you planted.

Apple trees and many other fruit trees are grafts.

I am surprised no one on the tree forum warned you that an apple seed will not produce an apple tree with edible apples!

what is in the pot???

plain ole dirt, more properly called soil ..

or potting media???

it really will make a difference, as to performance ...

i have rogue tree seedlings all over the yard ....the size of yours seems consistent with my experience... maybe 2 leaves the first year.. 4 leaves the second year... then 2 foot tall .... the third .. trees need to develop a good root structure.. before they move toward the sky ...

PS with my 10 year old daughter ... i have been through this whole thing... what a nightmare.. lol ... as noted.. you will have a weed apple.. barely lucky if the thing sets edible fruit in 10 years ... they mysteriously die in my yard.. and one of two things happen ...

if she accepts the mysteries of life.. she plants other things.. and we move on ...

if she is really broken hearted about it.. i promise to take her shopping for a real grafted tree in spring... or when you get your new house ... we both win this way.. i get a plant that is actually worthwhile.. and she gets a plant that she will love.. and we shared the time together.. picking it out.. and planting it.. etc .... google stark brother nursery for info about apple varieties... i mail order a bunch of stuff from them over the years.. though not recently ...

Its still an apple tree just genetically different like human children are from their parents. The one I was growing from seed I was going to just graft later but the heat killed it. I'll probably just wait until I prune in the winter and try root hormone to grow from a cutting. And keep it inside until February/March.

"Its still an apple tree just genetically different like human children are from their parents."

I'm not sure that that is such a good analogy. First the quality and taste of the fruit from the new tree is likely to be much less than the apple from which the seed came. The apple really can fall far from the tree (or in this case, the other way around).

Secondly, it's very likely that the tree from which the apple came was grafted. The seedling will eventually be many times as large as the parent tree and likely require much more management. Full size apple trees are very different in many ways than their grafted relatives.

Basically what I mean is it still has about 20% chance of putting fruit on which will be an apple but it will 100% taste different and possible not even good at all.

BTW you can just do what I was planning on doing and graft a known variety to it when its large enough.
