Q.Dogwood Injury

Anonymous added on April 11, 2011 | Answered

My dogwood lost several limbs during one of this year’s snowstorms. One large limb has oozed a great deal of bright orange sap. It kind of looks like it vomited. It is starting to look almost moldy and many flying insects are flocking to it. It is also spongy and slimy. What is it and what do I do?

The tree's branch likely broke after the tree came out of dormancy, and when this happens, the tree will "bleed" quite a bit. The bugs and mold are most likely attracted to the sugars in the sap. If possible, try to wash off the bled sap, but don't scrub too hard. Treat the area with a fungicide to keep away harmful fungus, but leave the wound to heal in the open air.

Might be flux, try spraying with a 50/50 mix of white vinegar and water. You'll probably need to spray it twice a day for about three days. If that doesn't clear it up in a few days, try treating with a systemic fungicide. I like the ferti-lome brand, but it doesn't really matter, just make sure it's listed for dogwoods. Make sure the tree isn't being overwatered. If you haven't already remove any broken limbs, cover the cut with pruning paint if you wish.
