Can you tell me why the trunk of this weeping mulberry is splitting? It is 14 years old and been moved twice. It's been in present location 2 years. We treated it for fungus this last summer. We are in zone 7a and haven't had any big swings in temperature this season.
We can't say exactly why, but as the following page tells, it could simply be a growth crack: http://extension.umd.edu/hgic/shade-trees-frost-cracks-sunscald-growth-cracks
We are not able to see details from your photo, but it looks like the tree may be planted too deeply or perhaps just mulched high? We would expect to see a flare outwards at the base of the trunk where the roots enter the ground (root collar). If it is planted too deeply, this needs to be corrected or it can lead to tree decline and death over time.
