How to Care for California Lilac Shrubs

The California lilac (Ceanothus spp.) is an evergreen, drought-tolerant shrub. It bears deeply fragrant lavender flowers and has an easy-care nature. With over 50 species native to California to choose from, the gardener can find a variety of California lilac growth habits, from small trees to groundcovers. California lilac shrubs are best grown within zones 9a through 10b on the U.S. Department of Agriculture Plant Hardiness Zone map. This is a plant that is so easy to care for, it develops problems if pampered too much.

Things You'll Need

Compost or peat moss

Pruning shears

Instructions

- 1
  Plant the California lilac in well-drained soil. It is prone to root rot and should never have water sitting at the roots. Mix 3 to 4 inches of compost or peat moss into heavy soils to help with drainage problems.
- 2
  Avoid the use of mulch around the California lilac. Mulch conserves soil moisture -- an environment that can kill this plant.
- 3
  Water the California lilac only during periods of extreme drought and then water to a depth of 6 inches. Allow the soil to dry completely before watering again. If you live in an area with cold winters, do not water at all beginning in late summer to give the California lilac a chance to harden off for winter.
- 4
  Prune the California lilac to keep it to the size and shape you want. Use pruning shears to selectively prune branches that are growing out of bounds. Other than controlling the size of the plant it needs no other pruning.
