Disease with crepe myrtle tree? And fruit tree protection question

Asked June 3, 2020, 3:42 PM EDT


I have a Crepe Myrtle Pink Velour tree that is 3 years old (I planted it 3 years ago. I guess it was around 3 years old when I got it from nursery).
It is about 5 ft tall. Since last year, I noticed something wrong with some leaves. As you can see in the picture attached, there is some white mold-like growth on the leaves and those leaves will die. Do you know what type of disease this is and how I can treat it?

The above is my main question. I have a minor question too. I planted a 5-in-1 fruit tree (with peach, apricot etc) 3 years ago. And the birds and squirrels always get to the fruits as soon as they are about to get ripe. Is there some organic way you can suggest to help me keep (some) of my fruits? By organic, I mean no harm to the birds or squirrels. We do plan to put out a bird feeder again, but I am a bit concerned it will attract too many birds and my fruits will disappear faster because of it.

Thank you very much,

1. Your crape myrtle has powdery mildew. If this becomes a chronic issue every year, we recommend replacing it with one that is disease resistant. This is a common problem, but there are many excellent crape myrtle varieties that don't get it. Here's more (which includes a list of good varieties at the bottom): https://extension.umd.edu/hgic/topics/powdery-mildew-trees-and-shrubs

2. One old trick is to sprinkle the fruit with just enough powdered lime to discourage the critters. You'll have to reapply after rains.

Sometimes harvesting before the fruit gets too sweet will beat them to it.


Thank you very much for your helpful information and suggestions on both issues, Ellen!
