About a week ago, I took this small apple seedling and I repotted it. Its next to freezing temperatures, and I havent been back to the location its at in a week. I came back today, the top leaves were shriveled up, I expected it to be dead already due to how cold it is, but now its got big red buds. What do you guys think is happening and what should I do with this apple this winter. Its already been exposed to freezing. 10 minutes ago I put moss inside the pot thinking it might help with insulation. I also placed the pot inside a larger pot thinking it may help some.
