Why haven't agapanthus reflowered after planting in ground?

Agapanthus may not reflower after planting due to several factors, including inadequate sunlight, poor soil drainage, or overwatering. They thrive in well-drained soil and need at least six hours of sunlight daily to bloom effectively. Additionally, if the plants are still establishing their root systems, they may prioritize growth over flowering in their first year. Lastly, excessive nitrogen in the soil can promote foliage growth at the expense of flowers.
