Water requirement: No need to water unless prolonged drought occurs.
Fertile, humus-rich, well-drained soil (pH 7.0)
You can plant lilacs in spring or in fall but it is best to do so in fall. Make sure the site drains well as lilacs do not like soil that is too damp and will not bloom.
If you decide to plant lilac in a container, ensure it is at least 12inches deep and 24inches wide as lilacs need a lot of space for their roots and this will help insulate against cold or heat.
In spring, add a thin layer of compost under the plant, followed by compost. Do not over-fertilize. Once your lilac has finished blooming, spread some well-rotted manure around the base.
Prone to attacks sfrom slugs and snails. Powdery mildew may occur after a summer of hot humid weather.
Spread: 8-15feet tall, 6-12feet wide.
Trim the bush to shape it once they bloom in early spring. Remove suckers and any dead wood. Do not over-prune as it can result in the loss of blooms for a couple of years, but pruning once a year in spring is recommended.
