Prune ceanothus in late winter or early spring, just before new growth begins. Focus on removing dead, damaged, or crossing branches to improve air circulation and shape the plant. For rejuvenation, you can cut back older plants by one-third to one-half, but avoid heavy pruning on younger plants, as they may not respond as well. Always use clean, sharp tools to make precise cuts and promote healing.
