Help with Lavender Twist Red Bud tree

[dustinsc]

Hello arborists!

I have a Lavender Twist Red Bud tree which is 3 years old. It has some spots on the leaves, and some browning on some leaves. I've attached some pictures. Is there something I should do to keep the tree healthy?

Thank you!
Dustin

While I am not familiar with the diseases or conditions prevalent in Utah, I can pass along some general advice.

That looks like a fungal leaf spot of some sort, which is probably compounded a bit by some dry conditions. I also am not familiar with that particular variety of Redbud. The leaves look a bit heat stressed to me.
In general, most fungal diseases cannot be effectively treated once you see the symptoms. Prevention is key, and you are starting at the wrong time of year. Also, most leaf spot diseases are not going to cause any critical injury to your tree. They are generally considered cosmetic problems, unless the tree is otherwise stressed or in poor condition.

How much water has the tree been getting recently?

Also, your post seems to have gone undiscovered. Perhaps I can page one of my "betters".

Do you guys have any opinions on this?

Good advice pdqdl, I would add your probably looking at anthracnose and powdery mildew. Fungicide treatments should start early at bud break next spring.

I don't see much powdery mildew; I don't think I've ever seen it on a redbud. Maybe I should look a bit harder?

I kinda figured those white spots were dust not washed off by a very light rain. I can see droplet patterns...

Distorted leaf surface is a symptom of powdery mildew.

See! I knew there was a reason I hollered you up.

It looks like the pros have the light work covered!




It is best to not let irrigation wet red bud leaves.

Here's a boatload of info on the origin and history of the Lavender Twist Weeping Redbud.

Thank you Connie Covey.
