Bonide All Seasons Horticultural Spray Oil gives you the most flexibility on when you can apply so you could apply even if it gets to freezing at night. 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. Please refer to the product label for complete application instructions.
