Hard Brown Scale on Large Kentia Palm

Question

I have several large Kentia Palms, ranging from 6′ to 15′ of trunk growing in my yard. They are getting a hard brown scale that starts near the bottom and moves up the trunk. It looks more like brown paint specks than the scale I have seen on houseplants. Where the scale has died off, the trunk is gray. The scale does not affect any other plants, even the Bromeliads growing on the trunks.

Answer 1

Try pruning out any discolored leaves. Neem oil is also effective treatment for the scale issue. This article will help you with the scale: https://www.gardeningknowhow.com/houseplants/palms/sticky-palm-tree-leaves-treatment-for-palm-scale.htm
