Sweet Broom Not Blooming After Two Years: Fertilizer and Mulch Fix

Why No Flowers?

Sweet broom (Cytisus) blooms on new growth. If plants are green but flowerless after two years, they likely need nutrient boost and weed-free root zone.

Action Plan

1. Apply balanced granular fertilizer now.
2. Mulch with 2–3 inches of well-rotted compost (suppresses weeds, feeds slowly).
3. Repeat fertilizer in early summer.
4. Ensure full sun and well-drained soil.

Outlook

With improved nutrition and reduced competition, flowering should resume next spring.
