Should I use Bonide All Seasons Horticultural Spray Oil or Dormant Oil on young (and mature) apple trees?

I'm confused as to which oil is best for my dwarf and semi-dwarf apple trees and when is best to apply whichever is recommended.

Answer:

The Bonide All Seasons Horticultural Spray Oil  gives you the most flexibility on when you can apply. It can be applied during any season at the dormant stage (no leaves), delayed dormant stage (green tip stage), and the growing seaons as spray to control overwintering eggs. For apple trees, the product label recommends to apply anytime from the GREEN TIP stage through DORMANT stage.  Hi Yield Dormant Oil can only be applied during the DORMANT stage prior to bud swell according to the label.  For specific application recommendations, please contact your local cooperative extension office
