Spider Mites on Cucumbers
Spider mites are tiny and easy to miss at first — pale stippling on the leaves is usually the earlier sign, with the fine webbing they're known for showing up only once the infestation grows.
Possible Causes
- Spider mites — tiny, barely visible pests that cause pale stippling on leaves and fine webbing once the infestation grows
- Nutrient deficiency or underwatering, which can cause similar pale, faded leaves without any webbing
- Sun scorch from intense direct light
What to Check
- Fine webbing on the underside of leaves or around the stem
- Tiny moving specks up close (a magnifying glass helps)
- Recent weather — hot, dry conditions favor mites
- Whether the fading is even across the plant or shows up in patches first
In a light infestation, webbing can be hard to spot at first — pale stippling on the leaves is often the earlier sign.
