can I apply organic fertilizer and lime to a lilac bush at the same time or should it be separately?
It's a 2 yr old bush in partial shade that has had minimal flowering. Should I remove the 2-4 inch of mulch from the base before applying fertilizer?

If you intend to replace the mulch with fresh mulch then you will remove it. If you intend to keep it in place, then the fertilizer can be applied as a topdressing. Both can be applied at the same time with no worries.
