Anaheim Pepper problems — and how to fix them
Anaheim Pepper (Capsicum annuum 'Anaheim') 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.
Blossom-end rot
Sunken leathery patch at the pod tip from calcium uptake disrupted by uneven watering; keep moisture consistent and mulch.
Sunscald
Pale, papery patches on exposed pods in intense sun once foliage thins; maintain leaf cover and avoid over-pruning.
Slow start in cold soil
Peppers stall and yellow below 15°C; wait for warm soil and use cloches or black mulch to lift temperature.
Aphids
Cluster on new growth and curl leaves; dislodge with water, encourage ladybirds or treat with insecticidal soap.
