|This will be my 4th summer with my lilac bush. It is growing alot - however it hasnt gotten any flowers on it yet. Why is that?
|Some of the smaller leafed types of lilac simply do not bloom at an early age, so if you have one of those that could explain it. However, lilacs may fail to bloom if they are in need of more sunlight, if they have been pruned at the wrong time of year, or if they have not been pruned regularly over the years. Since your plant is so young, it would not have needed much routine pruning yet, if any. (Routine pruning would be to remove the faded flowers and to remove any suckers smaller than a pencil each spring. After bloom, also remove some of the oldest stems by cutting them at the base, at the ground. This causes the plant to constantly renew itself and stay vigorous. It also helps it stay shorter and bushier.)
