Answer: Cytisus (sweet broom) requires full sunshine and dry soil to perform well. If your broom isn't getting adequate sunshine, or is getting too much water, bloom will be sparse. Move your plant to a sunnier spot and provide very little water this season. It should flower as soon as it adjusts to its new home. Brooms are generally disease and insect pest free so I think the problem is cultural. Hope this information helps you troubleshoot.
