Why 'Dark Star' Ceanothus Has Few Flowers: Age, Pruning & Fertilizer

A one-gallon Ceanothus 'Dark Star' doubled in size but produced only 5 flowers in Year 2. Three likely factors:

1. Fertilizer Overload

Excess nitrogen → vegetative growth at expense of flowers. Stop fertilizing.

2. Wrong Pruning Time

Spring bloomers set buds previous summer. Any pruning after July removes them.

3. Juvenility

Small plants may need 2–3 years to reach flowering maturity.

Advice

• No fertilizer.
• Prune only right after bloom (if needed).
• Be patient — it's establishing roots first.

Ceanothus thrives on neglect: lean soil, no summer water, no pruning.
