I planted a lilac in May of 2008 and it really hasn't grown at all. The leaves have continually turned brown at the edges and/or inside areas and curled up. Often they would just eventually drop the brown areas and look ragged. Now some new leaves and shoots are trying to grow and the edges of those are turning brown as soon as they emerge. I watered regularly during the drought in the summer and have sprayed with fungicide, thinking that could be the problem but with no result. Any ideas? I have tried to attach a picture. Hope it works.
