Troubleshooting
'Lemon' Cucumber problems — and how to fix them
'Lemon' Cucumber (Cucumis sativus 'Lemon') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Bitter fruit
Caused by heat, drought, or uneven watering raising cucurbitacin levels. Keep plants steadily watered, mulched, and unstressed; pick fruit young.
Powdery and downy mildew
White or yellow patches on leaves in humid, crowded conditions. Improve airflow, water at the roots, and remove affected leaves promptly.
Cucumber mosaic virus
Mottled, distorted leaves and stunted growth spread by aphids. Control aphids, remove infected plants, and grow resistant varieties where possible.
Poor pollination
Outdoor types need bees; few pollinators means aborted fruit. Encourage pollinators or hand-pollinate, and avoid letting plants dry out at flowering.
