What, exactly, are the risks of repotting deciduous trees and conifers late in the season (May through August)?
If you MUST slip pot out of season (or up pot out of season) use the same kind of soil the tree is already in. That way, there is no major difference between the new and old soil. The tree won’t even notice.Yes, the risk will vary by species. I would repot out of season only if the risk of not repotting is high. Usually you can make some holes in the rootball to increase drainage if necessary and limp along until spring. Most trees can be slip potted off season - moved to a bigger pot with better soil and little to no root disturbance. If you do that you need to pay attention to the differing watering needs of the old soil vs the new soil. Some trees don't seem to mind as long as you don't get crazy with root work (elms, olives), but even these can suffer if you're not careful.
Or just do them in spring before bud break.So for deciduous....in that we MUST remove some foliage to prevent over transpiration
