Frequently asked questions
Do lilacs grow well in the Bay Area?
Many lilacs can grow well with full sun, good drainage, and enough winter chill. Inland areas tend to be easier than cooler coastal pockets.
How much sun do lilacs need?
Full sun is best. More sun usually means more blooms and stronger fragrance.
When do lilacs bloom?
Most bloom in spring. Bloom timing varies by variety, so you can extend the season by mixing early and later bloomers.
Do lilacs need a lot of water?
They like consistent moisture while establishing. After that, they prefer deep, occasional watering rather than frequent shallow watering.
Should I deadhead lilac flowers?
Deadheading can improve appearance and direct energy into growth. Pruning is best done right after flowering.
Why is my lilac not blooming?
Common reasons include too much shade, pruning at the wrong time, too much nitrogen fertilizer, or not enough winter chill.
Are lilacs good for hedges?
Yes. Many varieties make excellent flowering hedges when spaced appropriately and lightly shaped after bloom.
Are lilacs safe around pets?
Lilac is generally considered low concern, but pets should not chew ornamental plants. If you have a pet that eats plants, place shrubs out of reach.
