River Birch - Yellow Leaf Chlorosis

I have a river birch that each year suffers from Yellow Leaf Chlorosis when the weather starts to warm up here in St. Louis. I've read that a combination of adding iron and lowering the pH can be an effective treatment. Do you have any suggestions on a product I can use?

Thanks!!!

try a product called Ironite or an application of 15-0-15 fertilizer.

I have a River Birch with the same problem. It otherwise looks to be very healthly and grows like a weed. The tree looks great but does drop leaves each year, it has already started this year.

Is this something I need to be concerned about for the longterm health of the tree?

since you mentioned the leaves dropping i did a little looking.
the yellowing is probably not chlorosis. take a look at this :

Possiblility... but I really does look like Chlorosis. First, it is happening in the spring and early summer. The Article notes that leaf blight generally happens in the late summer. Also, the yellow leaves on my tree have the green veins that corresponds to the description of chlorosis I've seen. though. .i'm definitely not an expert and I appreciate the follow-up.

The article notes leaf blight generally does not cause long term damage to the tree. Does chlorosis?

Thanks

no, but it's indicitive of soil nutrition issues that you should address. you won't see the leaves going back to green like a lawn would but the new leaves should be fine.

How to get invasive plants out of my garden?

M

mross on May 30, 2009

I have 2 very invasive plants in my garden that I want to get rid of. The first is Chameleon Plant (Houttuynia Cordata) and the other one is Gaillardia x Goblin Kobold. I've sprayed these plants numereous times with Spectricide and Round-up systemic weed and grass killer. Which I've used for years on other weeds with good sucess, but the Chameleon and the Gaillardia keep coming back. The specticide/Roundup appears to kill the plant but a week or two later, the plants are coming up again in the same spot and in other areas as well. I'm concerned that they will get out of control and take over my entire garden, if I don't get rid of them. I've even tried digging the Gaillardia out, but it was impossible. The roots are everywhere and when you barely touch the plant or root, they break off, so you can't get the entire root out. Is there another chemical they I could spray them with, that would kill them completely? Please help, I'm worried I will wake up in the middle of the night and these plants will be growing in my bed!
