Q.purple plum
We have a Purple Plum tree. This purple plum does not get the plums always. It seems to not look as good as it has in the past. One of the main trunks has started to split apart from another main trunk. We have put a spike through another type of tree before and it mended itself. Could we do this to this tree? If not, what else can we do to help it along or survive hopefully longer?

Yes, you can bolt the split together. Most of a tree's living tissue is at the surface of the trunk, so bolting the split together does relatively little damage to a tree and can help support it while it heals.
I would treat any wound areas with a fungicide to help prevent fungus and rot from setting and and keep a sharp eye out for pests and treat them quickly if you spot them. They tend to be attracted to weakened trees.
