What causes the tips of agapanthus leaves to turn yellow?
Although agapanthus do well here and are popular, they do not like it when temperatures reach the 90s. This causes dieback of the leaves – the tips of the leaves turn yellow, then brown. It doesn’t look good, but they will recover.
What to do when leaves start turning yellow?
- Step 1: Check for “Moisture Stress”
- Step 2: Look for Unwelcome Critters.
- Step 3: Let Them Soak Up the Sun.
- Step 4: Protect Them from Cold Drafts.
- Step 5: Make Sure They’re Well-Fed.
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.
