Even a few minutes of exposure to air, will have negative effects on root regeneration. Keep roots protected from sun and drying winds as much as possible. Keep roots moist and covered until just before planting. Pruning at planting time Everyone has their preferences and the training system protocols do have an effect on how to handle trees at planting. One of the more confusing issues brought from Europe in the last few years has been the planting of feathered trees and the question of heading height.
Some growers prescribe to no pruning at planting time.
Unfortunately, I have seen more negative effects with this strategy than positive. At planting, the need to balance top growth with root growth is still important. Reduce the number of growing points in the new canopy to avoid stress. Sweet cherries should be headed at 36-40 inches. We do not recommend heading of tart cherries.
