Lilac shrub

Hi, can I prune my Lilac after it has flowered to allow new growth?

    Yes, in my experience just after the flowers have faded is the best time. Next season's flower buds will set almost immediately and the earlier you do it the more energy will go to the new shoots. In fact leave pruning till later and you risk not having flowers next year.

    Thank you Amanda for your reply. The Lilac has no branches, underneath the top growth, if I cut it down will this kill the plant?

    Hi Liz, I cut back my Lilac very hard 2 years ago. Don't worry it comes back more vigorous and gives much stronger blooms after missing a year of blooms. As Amanda said i did miss one year of blooms

    You can prune lilac any time, but if you want a good display of flowers next year, about now, as Amanda suggests, is the time to do it. And Mick is right about them growing back strongly. Really they are just glorified privet!

    Thank you Amanda, Mick and Stafford Lake Nursery for your comments and advice, the big pruners are coming out, as soon as it's finished flowering. I have had this shrub and another climber plant, Olearia, I think! This has white flowers too, I think I will hard prune that too, it's about 10 years old, looks a bit boring, it's only got three stems on it.
