Agapanthus will thrive with consistent watering, about 1” a week during spring and summer. The soil should be kept slightly moist but never waterlogged. In fall and winter, allow the soil to dry out.
Why are my agapanthus leaves dying?
Overwatering and too much moisture on the leaves can contribute to this infection. Symptoms include brown spots on the leaves that can sometimes have purple edges. In the case of a severe infection, the spots turn black as the tissue dies and foliage can turn yellow, eventually dropping from the plants.
Should I remove leaves that are turning yellow?
Removing the leaf will let the plant focus its nutrients on healthy leaves. A yellow leaf has lost its chlorophyll (pigment) and it can’t turn green again even after you correct the problem.
