What is wrong with my lilac tree?
First time post on the forum and inexperienced gardener... Can you help me identify the problem with my lilac tree?
Leaves have turned yellow with exception of the veins which are still green, some browning as well.
Before they turned yellow there were notches cut out of the edges of the leaves, was having this issue on some nearby gooseneck loosestrife - initially thought it was aphids but now think it's vine weevil. Thought the yellowing/browning was due to the pests but now think it could be some sort of disease?
Only been at the property for 2 years so experienced 2 flowering seasons - first year was good, cut back all flowers once they were finished. This year there were fewer flowers, still removed them once finished. Shortly after this the "pest" issue started.
Similar thing seems to be starting on the buddleia bush next to it (also in images).
Depending on the issue I'm wondering whether it's risky to plant anything new next to these trees?
Appreciate your help!

If the plant hasn't had enough water it won't be able to absorb nitrogen which would cause the yellowing of the leaves but leaving the veins green.
A deficiency of other nutrients may also be the cause, but overall I think it's a lack of water is the main reason. The nutrients are in the soil, but the soil was too dry some weeks ago for the plant to absorb them.
I'd guess that next year your lilac will be ok - assuming we get enough rain.

Yesterday I noticed almost all of them have sent out new leaves and they're all in flower but the stems are about 18" and not the usual 6-7ft.
At least they're still alive

Hopefully next year will be back in full swing.
