My Lilac tree looks troubled. Can anyone recognize the problem? It was planted 13 yrs ago. It hasn't been limed in the last 8 months and it has no mulch.I feed it 6-8-6 every spring & fall at 1/2 dosage, also spread a bit of compost ea spring. I water it 1/week with a seeper hose for about 10 mins in this heat. It has never been pruned. The 2 images were taken Jun17 & Jul 20 /'10 Thank you in advance.
Yes, it has a problem. Maybe it's bacterial, or maybe even something like borers...could be related to the dull and damp spring we had this year.
Thank you for your reply. I checked for borers but saw no signs of them. Must read up on bacteria. Ginger.
