| I have 2 lilac bushes that refuse to get full. They get some flowers on the very top, but that's all. Western North Carolina location. |
| Lilacs bloom on new wood and they develop flower buds in the late summer for the following year's bloom. So, to make your lilacs bush out, prune them immediately after flowering has finished. This will give them all summer to develop new growth and new flower buds for next year's floral display. If you don't prune at all, the bushes will simply grow high, with flowers at the very top of the plant. |
