redbud tree leaves turning yellow with brown spots

7 years ago

Not sure if i should be worried or not but the leaves on my redbud don’t look right. We planted it a couple months ago. Right now it gets watered a couple times a week. We live in central California (Tracy) and we have clay like soil (although we added good soil when we planted). Leaves are turning yellow but have brown spots on the under side. Is this a fungus?

    Are the other redbuds in your neighborhood still green?

    regardless of where you live.. didnt fall start last week???


    and it was recently transplanted ... and its a largish plant ... its stressed ...


    and finally.. its a deciduous tree ... the stresses are making it shut down a bit early ...


    i am presuming this is a eastern redbud.. Cercis canadensis ....of which i am familiar... if not.. then my answer might change .... i only mean to point out that your use of a common name can lead to confusion .... so use of the latin name would make it specific ....


    one of the reasons trees are planted dormant ... is that you dont have leaves to worry about on deciduous trees .... or they are dormant on evergreen plants .... either way.. you usually just dont have to look at something like this.. and then worry ...


    anyway.. just water deeply and properly with near drying before repeating ..... and see what happens .... see link on watering ...


    since it deciduous.. there is no use spraying anything on leaves that are going to fall off this time of year ... imo ...

    Yes fall did start last week...lol. I’m more concerned with the brown spots on the underside of the leaves. It’s on the green leaves too and has gotten worse. I did ask the nursery owner whom I bought it from and he thought I had something called

    Verticillium wilt. Although I looked it up and don’t necessarily agree with that diagnosis.

    If it’s just the transition into fall then that would be awesome. There are no other redbuds in the neighborhood that I can compare it to and this is the first year we’ve had it so it‘s new for me.

    Spider mites could be the problem. I’ll have to look into that further.

    oh and it’s a western redbud. Other than that I don't have the technical name. Thanks to everyone who have responded!

    Western red bud is Cercis occidentalis. And that just looks like the effects of some drought stress or the tree being allowed to dry out at some point in time. Planting at the height of summer could certainly have contributed to that situation. It is most definitely not Verticillium wilt (although drought can be a contributing factor to that issue) and it really doesn't look like either spider mites or rust. And rust is typically not an issue with western redbuds.

    I personally would not be overly concerned about this. As noted previously, it is getting late in the season and the leaves will be drying and dropping on their own accord soon enough. Just make sure it gets adequate deep waterings as needed.

    And while we're talking about tree health, it would be best to remove that shipping stake as soon as possible. It will only cause more problems as time goes on. Most trees don't need staking in the first place and when they do, there's better ways to do it that won't cause more damage to the bark and root system.

    If staking is needed, the stakes should be located away from the trunk a good foot and a half. And the material around the trunk should be soft and flexible. It should also have some stretch to permit the tree to sway some in the wind. If the tree is held too tightly, the root base and trunk won't develop properly. Here's a link to with information on how to stake and how long to keep the stakes on, most of the time it's only for a season or so and the tree will be secure in the ground.

    It looks just like my 3 redbuds. I live just south of Sacramento and I planted these about 3-4 years ago from "sticks". They grew very well but the leaves are a big disappointment to me. I was expecting color but got the muted brown/yellowish colors. I would not plant another.

    IME, only the red leaved selections - like 'Forest Pansy' - develop any sort of fall color. Otherwise, it is pretty nondescript :-) That would not be a factor in my choosing this tree but rather on other attributes......size, flowering attributes, etc.

    Leaves look awfully large for Cercis occidentalis.

    Mine looks a bit like that (although bigger)...am presuming this anomalously hot and dry summer was not to its liking but I am not overly concerned. I did deal with verticillium wilt (mine was originally a grafted Forest Pansy) - the canadensis rootstock survived though and has a graceful shape and nice spring colouring) - the die back was rapid, extreme wilting and drying and total branch death. Not a bit of mottled discolouration. Try not to fret (yet).
