Topic: Split Trunk on a Lilac Tree -repair or the chop?

[George the Pigman]

I have an old lilac tree (more that 25 years old!) in our back garden and there is a long split (about 2 foot long)down the trunk on the left hand side. I would say the gap at its largest at the tope end is a couple of inches wide. If I took it out I would lose about a third of the tree. However it has been suggested that I simply put a tie around the crack to stop it getting bigger.
Would it work or should I give that section of the tree the chop?

I reckon take it out.  My lilac had bacterial blight a few years back (leaves and flowers turned brown and died back looking awful) ... the advice was to prune it within an inch of it's life, right to the ground.  A couple of years later and it's back to the same size it was and healthy.  I think they're difficult to kill!

If mine can lose the whole of the tree and survive - yours can survive losing a third.

I would suggest removing it.  It will be a source of infection.  2/3rd of a tree is better than no tree at all.  It will also show you whether there is any infection below the split.

My main problem to date has been wood pigeons eating the leaves in the summer. Apparently they are a mild narcotic for them! Not seen any with rotating eyeballs as yet!

Just read this ..Oh I do hope you haven't chopped it down ! I would definitely do the bandage thing . ...I had a plum tree which split in the gales  during last Autumn. I bandaged it with plastic tape and it has healed beautifully ... I will give it a bit longer time and then remove the tape .
Lilac is such a lovely tree and heavenly scented flowers..worth saving !  Debbie

Even if it is cut back, lilac's extremely tough, and it'll grow back. I've got some in my hedge; I coppiced it way back, and it just grew back again perfectly happily.

Yeah - don't worry woodypecks ... you can't kill lilac just by chopping it down!  It's like Elder!

Well an update. In the end I had the whole main stem that had the crack in it cut down to the base. Turned out it was hollow all the way through. Glad I did as Storm Doris struck a few days later!
I've got a number of other stems on the lilac that look fine so I should have some flowers this year.
