Lilacs care question.

[Gary350]

Lilacs have finished blooming when are we suppose to fertilize and trim and what kind of fertilizer.

Trip? No idea what you mean.

I have never fertilized my lilacs, neither the huge old one or the two younger ones, one of which was a little volunteer I moved to a new spot. They fend for themselves quite well.

See my post here:

all I do is deadhead and prune a little (mostly cutting the dead wood out and opening up the center a bit so sun, air etc can get through, keeping branches from rubbing against each other)
