California Lilac #ProPlantTips For Care

Ceanothus are very low maintenance once established and they don't need or like any coddling or fussing. In fact, too much water and too-rich soil is a surefire way to kill them.

Give these sun-lovers at least 6 hours of direct light a day. Though tolerant of some shade this will greatly affect the flowering and density of the plant.

Give young plants low amounts of regular water during their first season only. This will help their roots establish themselves in your soil. However, they truly thrive on low water and barely require summer watering once established. They are truly perfect for the xeric garden and drought-tolerant landscape!

Adapted to a wide range of different types of soil and thriving in poor soil, in fact, California Lilacs do their best in lean soils that have great drainage!

If your soil holds water, you'll need to use raised beds or plan to mound up. Add additional soil in a mound 18 - 24 inches high, and plant directly in the mound. 

Prune right after blooming to remove spent flowers and to keep your plant looking even and full.
