We're guessing that the most

By Almanac Staff

We're guessing that the most likely cause in your case for no blossoms would be that the bush is still too young to flower. Some lilacs may take up to 5 or 7 years to start blooming.

Although you have followed the directions which came with the bush, it might be good to double-check that the plant is still getting at least 6 hours of sunlight (has other growing vegetation started to shade your bush?), and that the soil is slightly acidic to slightly alkaline (pH 6.0 to 7.5). A fertilizer high in nitrogen promotes leaf growth over blossoms; if you need to fertilize, choose one whose N-P-K ratios are about even, and only apply a small amount; lilacs don't do as well in rich soil. Also, make sure that the plant is getting enough water (about an inch per week).
