Know before you buy
The dormant season refers to the time of year when your trees and shrubs are not actively growing, typically in late winter or early spring before buds begin to break. Applying the spray during this window allows you to target overwintering pests without harming the plant's active foliage.
Yes, this spray is formulated for both. However, note that the mixing ratios differ: use 3 tablespoons per gallon for ornamentals and 6 tablespoons per gallon for fruit trees.
You must apply this product when temperatures are below 85°F to avoid potential phytotoxicity, which is essentially plant burn. Applying mineral oil in high heat can stress or damage the plant tissue.
This mineral oil formula works primarily by smothering pests and their eggs on contact. Because it targets all life stages, thorough coverage of the entire plant surface is essential for it to be effective.
You will need a standard garden sprayer to apply the mixture. Ensure you have a clean sprayer and follow the mixing instructions carefully to achieve the proper concentration for your specific plants.
