Q.Why Hasn’t My Agapanthus Bloomed? It Has Been In The Same Spot For 2 Years. It Appears Healthy But Hasn’t Bloomed
I live in zone 8 and it is in full sun.

Because all of the other factors are likely within range, I suspect that there may be too much nitrogen and not enough phosphorus and potassium in the soil. Fertilizers for BLOOMING plants will help, should a test reveal a lack of phosphorus and potassium.
