It's time up here to put in orders for bare root trees, whether fruit trees or otherwise. We use Musser Forests, Stark Bros, and other websites where we can find what we want.
While November might have been the best time to plant them, the second-best time is as soon as you can get a shovel into the thawing ground.
Bare root trees establish themselves quicker than burlapped or potted plants. There are many sites and Youtubes which explain how to properly plant bare root plants. It's not a bad idea to soak the roots for a few hours before planting. When you plant them in dormancy, water them in well and then withhold any watering until green shoots appear.
In the first summer, a deep watering once or twice a week works well. After the first summer around here, no watering is needed after that. In the first Spring, it's recommended to pinch off any fruit tree blossoms that appear, so the plant can devote itself to establishing itself in its home.
I have ordered three Crabapples (edible crabapple, semi-dwarf,as in photo. Not the ornamental) to put in as soon as we get some thaw. Right now we have 12" of snow and the soil is like a rock.
