Bell Pepper Problems
Capsicum annuum (Grossum Group)
Bell peppers are sweet, thick-walled Capsicum that need full sun, warmth, and steady feeding to set a good crop of fruit — blossom end rot and poor fruit set from temperature stress are the most common growing hurdles.
All Bell Pepper Problems
⚠ ModerateBell Pepper — Blossom End Rot on Bell Peppers
A dark, sunken, leathery patch develops on the blossom end (bottom) of the fruit, sometimes affecting several fruits on the plant at once.
⚠ ModerateBell Pepper Flowers Falling Off Without Setting Fruit
Flowers form and open normally but drop off within days without ever developing into fruit.
⚠ MinorBell Pepper — Sunscald on Bell Pepper Fruit
A pale, papery, or blistered patch develops on the sun-facing side of the fruit, sometimes leading to soft rot in that spot.
⚠ MinorBell Pepper — Small or Thin-Walled Bell Peppers
Fruits mature but stay smaller than expected for the variety, or have noticeably thin, less crisp walls.
⚠ MinorBell Pepper — Aphids on Bell Pepper Plants
Small soft-bodied insects cluster on new growth, flowers, and the undersides of leaves, sometimes causing distorted growth and sticky honeydew residue.
⚠ ModerateBell Pepper — Spider Mites on Bell Pepper
Fine yellow stippling spreads across leaves, with fine webbing visible on the underside in heavier infestations, especially in hot, dry conditions.
⚠ ModerateBell Pepper — Bacterial Leaf Spot on Bell Pepper
Small, dark, water-soaked spots appear on leaves, sometimes with a yellow halo, occasionally also affecting fruit with raised, scab-like lesions.
⚠ ModerateBell Pepper — Cold Stress Preventing Bell Pepper Fruit Set
The plant grows but produces very few fruits during unusually cool weather, with flowers dropping shortly after opening.
⚠ CriticalBell Pepper — Root Rot in Bell Pepper Plants
The plant wilts despite moist soil, and roots appear brown, mushy, and hollow when checked, often in poorly-draining containers or waterlogged garden beds.
⚠ MinorBell Pepper — Curled or Cupped Leaves on Bell Pepper
Leaves curl upward or cup, sometimes with a leathery texture, distinct from wilting.
⚠ ModerateBell Pepper — Blossom End Rot in Container-Grown Bell Peppers
Container-grown bell peppers develop blossom end rot more frequently than garden-grown plants, even with apparently attentive care.
⚠ ModerateBell Pepper — Whiteflies on Bell Pepper
Small white, moth-like insects fly up in a cloud when the plant is disturbed, with sticky honeydew residue and sometimes sooty mould developing on leaves.
⚠ MinorBell Pepper Fruit Staying Green and Not Ripening to Colour
Fruits reach full size but stay green rather than turning red, yellow, or orange as expected for the variety.
⚠ MinorBell Pepper — Yellowing Leaves From Nutrient Deficiency in Bell Pepper
Leaves yellow, sometimes starting with older growth and sometimes between the veins, distinct from simple watering-related yellowing.
⚠ ModerateBell Pepper — Cutworms Cutting Down Young Bell Pepper Seedlings
Young transplants are found severed at or just below the soil line, sometimes toppled completely overnight, with the stem chewed through.
⚠ MinorBell Pepper — Thrips Scarring on Bell Pepper Fruit
Silvery streaks or a rough, corky, scarred texture develops on the fruit surface, distinct from sunscald or other environmental damage.
⚠ CriticalBell Pepper — Mosaic Virus in Bell Pepper
