Topic tags/keywords: cherry tree diseases

I just noticed today that most of the cherry trees near my house a losing a lot of leaves.

The little ones growing in sheltered locations have about 1/2 yellow leaves. The big ones that catch some wind seem to have lost 1/2 their leaves. It’s just the beginning of August. This is odd.

I’m in North Alabama.

Has anybody else noticed this? Is this a widspread phenomenon? Is this normal (never noticed it before)?

thanks,
-Paul

On the left is a young cherry. On the right a hackberry. Between them, a black walnut.

Here on a waist-high sapling, is the yellow leaf with the purple spots.

Looking up into a 15’ young tree backlit by the sun.

Here’s a 12’ little tree right against the back of my house (that I need to remove anyway), with plenty of yellow leaves.

Ok I just found this

Looks like cherry leaf spot disease – a fungus.

I can’t find any reference to doing anything about it in black cherry, only for fruit cherry.

we’ve got this in our neighborhood here in seattle (or potentially a similar fungus). I had to cut down one of my fruiting ornamental cherries when i first moved in.

Apparently the fungus thrives in wet conditions. We’ve had more rain than usual this summer – have not had to water the garden at all. Hopefully, next year won’t be so bad. I would think Seattle weather would be ideal for this fungus.

Oddly, there are a few small (less than 6’) cherry trees which seem entirely unaffected.

Several of my BIG black cherry trees have a lot of dead limbs, leaf loss, and no fruit this year. Not sure if this is age or disease. The worst affected is over 3 1/2 feet in diameter :(

Yeah, but it will be fun to cut into lumber when it eventually dies. Not that I’m wishing that Andy.

Bill, The trunk is huge but only goes up ~4’ before it branches into 4 smaller trunks, 2 of which are pretty curvy. You walked under it several times when you were here: about midway between the mill and the house.

Probably didn’t notice it because I was busy scratching the chiggers already. :-)

Just kidding Andy. I get just as many chiggers at home if not more. They’ve been terrible this year.

I added some poor-quality cellphone photos of the cherry trees with this disease.

Have your say...
