Dogwood spot anthracnose

Asked June 5, 2018, 6:13 PM EDT

Hi, we have about 6 flowering dogwoods in our yard. They're probably fairly old trees. One of them has a heavy outbreak of spot anthracnose this spring (verified by arborist). Your webpage about this fungus says that fungicide won't alter symptoms once they're showing, so it's not recommended to spray that tree. My question is whether it would be a good idea to treat our other trees, which are in full leaf, as a precaution. We try to use very few chemicals so I would not do it if it's not necessary. Thanks!
