I have a lilac that was grafted into some kind of tree to make the lilac more of a tree than a bush. For several years, there were no issues. But this year, the mystery trunk has sprouted multiple branches of its own, which have grown much taller than the lilac.
Can I cut all of these branches back, or will that kill the whole thing? Is there a certain time of year that would be best to remove them?

Cut back anything that is not true to the type you want
