Quick reminders for planting apple trees
Be sure to consider graft union height to avoid problems in the future.
There is a rush in west Michigan to get trees in the ground before we get doused by rain again later this week. Here are a few reminders about apple tree planting.
- Keep the graft union at least 6 inches above the soil level.
- Six inches above the soil allows for the 2 inches or so of “sinking” that is commonly seen as soil settles after planting.
- Graft unions end up near or below the soil level, resulting in too much vigor that you will fight for the life of an orchard.
- A shallow planted tree can be easily corrected later in tree life compared to the task of trying to correct a deep planted tree.
- Be sure you check the work of your planting crew often to be sure planting is done correctly.
- Use a 20-inch by 6-inch board on its edge adjacent to the planted tree (perpendicular to the row) to check the depth.
- While the soil is still loose, pull trees up that are too deep and push those down that are too shallow.
