• Using Horticulture/Dormant Oil in the Landscape

    January-February is a good time to control scale insects on evergreen shrubs and trees such as camellias, hollies, bay laurel, myrtle, euonymus, citrus, photinias and boxwood through use of a horticultural oil spray. Fruit trees may be sprayed at this time of year in order to control insect eggs that may have been laid in bark and twig crevices.
