How to Get a Lilac Bush to Bloom More
Lilac bushes originated in Eastern Europe and the Balkans, although there are Asian lilac bushes as well. In all, there are over 1,000 different varieties of lilac bushes. They come in an array of colors that include purple, lilac, lavender, pink, blue and white. The size and type of bloom can vary, too. Some bushes are known to grow over 30 feet high, while others of the dwarf variety are less than 3 feet tall. The blooms can be single or double petaled. Since lilac bushes have such a beautiful aroma and shape, you may want to ensure that your plant is blooming more. Does this Spark an idea?

Tips & Warnings
You should be prepared for one full season without blooms after you transplant a lilac bush. They can go into a state of shock after transplanting. But, they will bloom again next season.
Since lilac bushes do not reach blooming age until they are three to four years old, do not be concerned if your plant is not of age and blooms have not formed. Just give it some time and you will rewarded.
