Apple in a Zone 3 season
Zone 3 gives about 123 frost-free days. Apple needs roughly 150 days from transplant. That is longer than the outdoor season here, so this one needs an indoor start, and even then it may want a tunnel or row cover to finish.
How to grow apple trees
Plant a bare-root tree in early spring while dormant. Most apples need a second variety nearby to pollinate; expect fruit in a few years.
