Ceanothus 'Concha' problems — and how to fix them
Ceanothus 'Concha' (Ceanothus 'Concha') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Root rot from wet soil
Overwatering or poor drainage rots the roots and collapses the plant. Plant in sharply drained soil and avoid summer watering once established.
Short-lived
Like most evergreen Ceanothus, lifespan is often only 10-15 years. Light pruning after flowering and lean soil prolong it; hard cutbacks shorten it.
Frost and cold-wind damage
Rated H4, it can suffer in hard UK winters and exposed sites. Give a sheltered, sunny spot, ideally against a warm wall.
Resentment of hard pruning
Does not regenerate from old leafless wood. Prune only the current season's growth lightly, never into bare branches.
