Maireen from Warren, Ma writes

Can I use Bonide All Seasons Horticultural Spray Oil on rosemary plant?

What are the mixing instructions?

Answer:

Bonide All Seasons Horticultural Spray Oil can be used on evergreen plants, such as rosemary plants. According to the product label, the application rate for Summer (foliar or cover) is 2-5 tablespoons of oil per 1 gallon of water if you are spraying for a labeled insect. For blackspot and powdery mildew control during the summer, do not exceed 5 tablespoons of oil per 1 gallon of water.
