Why are there spots on my chili pepper fruit?

Spots on the bottom of your peppers are often a sign of blossom end rot. This is a calcium issue caused by uneven moisture levels in the soil.

Check these first

  1. Check if the soil is drying out too much between waterings.
  2. Look at the location of the spots on the fruit.
  3. Ensure you are not over-fertilizing with nitrogen.

Likely causes

  1. Blossom End Rot

    Most likely

    How to tell: A dark, sunken, leathery spot appears on the bottom of the developing fruit.

    What to do: Maintain a consistent watering schedule so the soil never dries out completely. Avoid heavy nitrogen fertilizers that can interfere with calcium uptake.

  2. Sunscald

    Possible

    How to tell: White or tan papery spots appear on the side of the pepper exposed to direct sun.

    What to do: Ensure the plant has enough foliage to shade its own fruit. If the plant is sparse, use a light shade cloth during the hottest hours.

When to worry

Blossom end rot ruins the fruit, but the plant itself can still produce healthy peppers later. Remove affected fruit so the plant stops wasting energy on them.

Stopping it coming back

Keep soil moisture steady and avoid sudden swings in watering frequency.

Questions people ask

Can I eat a pepper with blossom end rot?
You can cut off the affected part and eat the rest if it is not mushy. However, it is usually better to discard it.
Do I need to add calcium to the soil?
Usually, there is enough calcium in the soil, but the plant cannot move it to the fruit without steady water. Focus on watering first.
