What are the benefits from applying Dormant Oil Spray and which plants should I spray?
Dormant spraying combines Horticulture Oil and Lime Sulphur to kill overwintering insects (such as scale and mites), insect eggs, and diseases on certain hardy landscape plants. Dormant Oil and Lime Sulphur are best applied to fruit trees, roses, ornamental shrubs like Highbush Cranberry and European Snowball, evergreens such as Cedars, Junipers, Euonymus, and trees like Hawthorn, Crab Apple, and Honey Locust. Do not use Dormant Spray on Beech, Butternut, Colorado Blue Spruce, Hickory, Holly, Sugar Maple, Japanese Maple, or Walnut. This powerful combination spray can only be applied when plants are completely dormant. Speak to the experts at Sheridan Nurseries for specific details on how and when to apply this product.
