River birch help

I need help I planted a river birch back in april and it has been doing great. Now for about a month it has randomly had leaves that are turning yellow with black spots in them. We have been getting plenty of rain here in eastern NC so i have not had to water it. Any help will be great as I do not want to loose this tree.

Plenty of rain doesn't mean that the tree is getting enough of it... roots take time to develop to get the tree to balance its intake with its leaf load... there's one possibility...

I have a poplar of many years that is growing healthy all the time but it starts dropping leaves around this time of year, every year... the peach tree is dropping some yellow leaves as are many birches in the forest...

If you suspect insects chewing leaves and spreading disease, it might be a good idea to get a systemic insecticide at your local nursey or hardware store... the stuff gets into the tree and stays for about a year...

As long as you've checked the root zone and it isn't soggy wet for long periods of time or dusty dry, I'd say you're fine...

Possible Leaf Blight problem.

I see it randomly up here, but this year and the lack of rain, it's been a non-issue.

A river birch is just a lousy tree. Leaf drop happen's every year no matter
what you do. I wouldn't plant one. This is not just my opinion, read more -

I have two 3-4 year old Heritage River Birches in my backyard, last week they were dropping leaves like crazy. This week we've had a decent amount of rain so the leaf drop has subsided. It seems to do it in "drought" conditions.

Same thing happened last month when we went through a 2-3 week period of no rain. They dropped a lot of leaves, then when we had a week of rain, the leaf drop stopped.

What no one has touched on is the fact that river birch are very susceptible to transplant shock, no matter how much you water them.

This is most likely the issue you are seeing. As long as they aren't all yellow or all dropping, and it isn't too dry or too wet, I wouldn't get concerned.

Brings back childhood memories. We had one in the parking lot of our neighborhood swimming pool growing up. We used to chase each other around trying to whip the other person with the sticks.
