Milky Substance on Plants


My Carissa Hollies have some milky looking stuff on the top of the leaves and I believe on the stems. This is the second season I have noticed this and they also have thinned out and do not look as full. Do you know what this could be and how to treat?


Anne's response

I think you may have an infestation of the scale insect on the plants. At one point it does look white and milky and you may notice some of the spots moving around a bit. One method of control is to use a horticultural oil spray on the leaves (front and back) and stems of the plant. Read the directions on the product very carefully as some products cannot be used in hot weather.
