Troubleshooting
'Jalapeño' Pepper problems — and how to fix them
'Jalapeño' Pepper (Capsicum annuum 'Jalapeño') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Flower and pod drop
Buds abort below about 16°C or above 32°C and in very dry air; keep plants warm, evenly watered, and shaded during heat spikes.
Blossom-end rot
Dark, sunken patches at the pod tip from uneven moisture; mulch and water consistently rather than adding calcium supplements.
Corking and ripeness
Fine tan stretch-mark lines (corking) are normal and a sign of maturity; pods can be picked green or left to ripen red for more sweetness and heat.
Aphids and spider mites
Sap-suckers thrive on warm, dry indoor plants; raise humidity slightly, encourage predators, or treat early with insecticidal soap.
