Q&A - What Is Splitting the Bark On My Maple Tree?

Question:
My maple tree has something eating away at the trunk. I saw ants on it. Are the ants doing this damage?

Answer:
What was thought to be ant damage actually turns out to be more related to heat and frost hurting the outer shell of a Maple tree. Ants being present can be a sign of aphids and of course their honeydew. Damage to your trees can often be secondary to the root problem. Make sure you investigate your garden environment for pests, weather exposure and disease before pursuing a treatment.
