What is the best way to treat a red oak with a continuing chlorosis problem? I've spread Ironite twice-in April and again in mid July with minimal improvement. How good is Cambistat, a product I read about on a web site? Thanks, Gwen

Gwen,

You will need to consult with an arborist about the product Cambistat and whether or not it will help your tree's particular problem. Usually when a red oak is chlorotic it is due to one of these factors: wrong species (eastern species in western high pH soil), soggy soil conditions (poor drainage), girdling or circling root at base of trunk just beneath the soil strangling the trunk at it grows larger. If it is this last cause you can cut and remove the root if you catch it early enough.

Thanks for the question. Please stop in again soon!
