Q.Lilac
I have a reblooming lilac I planted last year. It has now grown to about 4 feet and there have been several blooms in tiny doses then the deer have bittent them off. I left them alone but they are continuing to try and develop blooms ,Do I just cut it back and try harder to repel the deer or just leave it alone? I have read the articles on pruning.I do not want it to die.i was hesitant to prune during summer ,afraid i would cut too much.

Since it is newly planted, I would do nothing more than deadhead anything that has completely died off. Repelling deer would be your best option, for now.
