Chili Pepper Problems
Capsicum annuum
Chili peppers are one of the most satisfying plants for home growers. From mild jalapeños to superhot Carolina Reapers, they thrive with full sun, warmth, and consistent care — and produce for years when overwintered.
All Chili Pepper Problems
⚠ ModerateChili Pepper — Blossom Drop � Flowers Falling Before Fruiting
Flowers form normally but wither and drop off within a few days, without ever setting fruit. The plant otherwise looks healthy, with green foliage and continued new flower production, but very few flowers actually convert to peppers.
⚠ MinorChili Pepper — Leaf Curl on Chili Pepper Plants
Leaves curl upward or inward along their length, sometimes accompanied by a slightly leathery texture. New growth may emerge already curled. The plant otherwise continues growing, but the distorted foliage looks stressed.
⚠ MinorChili Pepper — Yellowing Leaves � Nitrogen Deficiency
Older, lower leaves turn uniformly pale yellow first, while newer growth at the top of the plant stays green. Growth overall slows, and leaves may be smaller than expected for the plant's age.
⚠ ModerateChili Pepper — Blossom End Rot on Peppers
A sunken, dark brown to black leathery patch develops on the bottom (blossom end) of developing fruit, while the rest of the pepper looks otherwise normal. The lesion doesn't spread as fuzzy mould, but it does soften and can allow secondary rot to set in.
⚠ MinorChili Pepper — Sunscald on Pepper Fruit
A pale, blistered, papery patch develops on the side of the fruit facing direct sun, usually after a sudden increase in sun exposure. The affected area may later turn white or tan and feel dry and thin compared to the rest of the fruit.
⚠ ModerateChili Pepper — Aphid Infestation on Chili Peppers
Clusters of small, soft-bodied insects gather on new growth, stem tips, and the underside of young leaves. Affected leaves may curl or become sticky with honeydew, sometimes followed by a black sooty mould growing on the residue.
⚠ ModerateChili Pepper — Spider Mites on Pepper Plants
Fine, silvery stippling appears on the upper leaf surface, with tiny moving specks visible on the underside when checked closely. In advanced infestations, fine webbing appears between leaves and stems, and affected leaves may yellow and drop.
⚠ ModerateChili Pepper — Powdery Mildew on Chili Pepper Leaves
A white to grey powdery coating appears on the upper surface of leaves, starting as small circular patches that expand and merge. Affected leaves may yellow and drop prematurely, weakening the overall plant.
⚠ ModerateChili Pepper — Poor Fruit Set Despite Healthy Flowering
The plant produces plenty of flowers over an extended period, but very few develop into peppers. The plant otherwise appears vigorous and green, making the lack of fruit puzzling.
⚠ MinorChili Pepper — Stunted Growth in Young Pepper Plants
The plant grows very slowly or barely at all after transplanting, with small, sometimes purple-tinged leaves and a generally weak appearance compared to expected growth for its age.
⚠ MinorChili Pepper — Leggy, Weak Stems on Pepper Seedlings
Seedlings grow tall and thin with long gaps between leaf nodes, and stems are noticeably weak and floppy, sometimes unable to support their own weight without staking.
⚠ CriticalChili Pepper — Root Rot in Container-Grown Peppers
The plant wilts despite moist soil, with lower leaves yellowing and dropping. When checked, roots appear brown, soft, and mushy rather than firm and white, sometimes accompanied by a sour smell from the soil.
⚠ ModerateChili Pepper — Bacterial Leaf Spot on Pepper Plants
Small, dark, water-soaked spots appear on leaves, often with a yellow halo around each lesion. Spots may merge into larger dead patches, and severely affected leaves yellow and drop. Fruit can also develop raised, scab-like spots.
