Maintenance Tips
Ceanothus ‘Concha’ is a dramatic, evergreen native shrub that sends out dark blue flowers for about 4-6 weeks in the late spring. This is one of the hybrids of the native California Lilac and can reach 4-8' tall and up to 12' wide. It is a large, dense shrub that is drought tolerant once established and can take most soil conditions. To keep the maintenance as low as possible, give this plant the room it needs to reach its full mature size. The amount of space this plant requires is often underestimated, leading to poor pruning habits, like shearing, to control the size. If it is planted in a tight space, it is best to use the thinning method of pruning, cutting off the longest branches to the interior of the plant to allow sunlight in and to allow it to keep a natural shape. Over-watering during the hottest months of the year can lead to both pest and fungal issues. Water infrequently and deeply throughout the year and keep the soil around the base of the plant fairly dry to help discourage pest and disease problems.
