| Recently some leaves on my bell pepper plant have gotten tiny yellow spots. What's causing this? Is it harmful to the plant ? I hope it's not dying. It's so close to harvesting. Thank you! |

| Pinprick yellow spots often are caused by spider mites feeding on leaf undersides. You should be able to see them and faint webbing with a magnifying glass. If you get a positive ID, gently wipe off the leaf undersides with paper towels dipped in soapy water. A few days later spray with insecticidal soap. If it's not spider mites it could be oedema -- burst cells from uneven watering, which look like rough bumps on leaf undersides. If that's the problem, the plant should outgrow it. |

| Spider mites make very fine stippling, more fine than in the picture. I'd suspect edema. what does the leaf underside look like? |

| Thanks for the replies! I think it's edema. |
