Troubleshooting
Burpless Cucumber problems — and how to fix them
Burpless Cucumber (Cucumis sativus 'Burpless Tasty Green') 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.
Powdery mildew
White leaf film in stuffy or dry-rooted conditions. Ventilate under cover, keep roots moist, water the soil not the leaves, and strip affected foliage.
Spider mite under glass
Mottling and webbing in hot, dry indoor air. Damp down to raise humidity and bring in predatory mites at the first sign.
Bitter or curled fruit
Even low-bitterness lines turn bitter or bend under water stress and heat. Keep moisture consistent and harvest young for the mildest flavour.
Collar / stem rot
Soft, browning stem base from water sitting against the collar. Plant on a slight mound, water around the base, and ensure sharp drainage.
