Lilac Tree

Hello

I have a lilac which is about two years old. Two of the three main branches have grown very long, disproportionately to the third. Should I cut them back, if so when and how? 

Cheers

    I think this is something that lilacs tend to do, I always chop mine - the tall stems that is - whenever I see them, and severely in October.  So far, so good. 

  • It hasn't ever flowered, so still ok to prune? Thanks for advice thus far.

     

  • Lilacs flower on 'ripe' wood - next spring the flowers will be at the end of the growth it has made this year. If you prune it now you won't have any flowers next spring, but sometimes you have to sacrifice the flowers in order to encourage bushy growth, or in order to restrict the size of the shrub.
