lilac never grows
I planted about 5 years ago and it is still the same size as when I planted it - what can I do?
I am listing a few links for you to refresh you on the growing conditions a Lilac needs.
Check soil conditions sunlight and watering to start. A soil test would be a good idea.
This will help you determine if you need to make any corrections.
Your local county extension office can help you with a soil test.
