I planted a lilac in full sun 3-4 years ago. Although it has had nice healthy foliage and has grown to approx 7 ft tall, it has not ever flowered. It is mulched and fertilized regularly and is a single specimen plant in that area. The yard has dogwood and other flowering shrubs and my vegetable garden is adjacent to the lilac bush so there are no obvious nutritional problem. Is there a specific nutrient that may be missing? Would appreciate any suggestions.
We have lilacs all over the place that have bloomed before, but this year zero, zip, nada, no flowers at all. It has me puzzled. I just figured that our warm spell pushed the buds a little too far and they all froze. Ric
