watering

California lilac should be watered regularly throughout the growing season. It prefers moist to slightly dry conditions, so water when the top layer of soil starts to look dry. Aim for deep waterings once or twice a week to keep the soil evenly moist. When it’s very hot and dry, it might need a little more water. Avoid overwatering, however, as this can cause mildew and root rot. During the winter, California lilac only needs to be watered occasionally during dry spells.

sunlight

California Lilac (Ceanothus Delileanus 'Gloire De Versailles') does best when exposed to full sun, 6 or more hours each day. It also does well in part sun locations, but to achieve the best flowering it should receive at least 6 hours of direct sunlight. Too much shade can negatively affect flowering, as well as affect the overall health of the plant.

pruning

California lilac should be pruned in late winter or early spring just before the active growth season begins. Prune Californian lilacs lightly by removing spent flowers and light shoots. Shaping the shrub can also be done, but old branches should not be removed, as this may cause irreversible damage to the shrub. Avoid pruning into old wood as new growth may not form and the shrub may suffer from dieback and decline. Prune 1-third or 2-thirds of each branch from the overall shrub to maintain the desired shape and size.
