Apple trees growing extremely fast after they looked 'sick'

I planted these apple seeds in November last year, and they grew until winter started here. Then they did not grow for very long, and the one had white stuff on its leaves. So I thought it is not going to make it. But about 2 weeks ago, it started developing these new leaves, which made me very happy I now keep them in my greenhouse, since our winter nights still get really cold for them. (quả óc chó)

congratulations, I wish you success in growing.

Hell yeah man! They are right at the size that you want to budgraft some good genetics onto the top and then stripping the lower foliage! Sweet! I do this too!

Thank you for the the post and pic i have been thinking about growing one and you have inspired me to try it.
