Whte Powder On Palms And Other Trees

Anonymous added on May 14, 2011 | Answered

I just bought a house with a beautiful garden, but neglected. I see the palm fronds and some other trees have what looks like dry, white powdery areas on the leaves. The camellias have gray or black spots and the leaves are discolored. The garden has been abandoned for several months. I'd love to make it beautiful again!

This is powdery mildew. Here is an article or two that you may find helpful: https://www.gardeningknowhow.com/problems/get-the-cure-for-powdery-mildew.htm

You can also try using neem oil to treat the plants.
