Troubleshooting
Baby Sweetcorn problems — and how to fix them
Baby Sweetcorn (Zea mays 'Minipop') 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.
Cobs left too long
If not picked within a day or two of silks showing, cobs become tough and starchy. Harvest young and often to keep them tender and sweet.
Cross-pollination from nearby sweetcorn
Pollination toughens kernels, defeating the point of baby corn. Grow well away from maincrop sweetcorn or stagger sowings.
Cold-soil seed rot
Germination fails in cold, wet ground. Sow into warm soil or start under cover and transplant after frost.
Slug and bird damage to seedlings
Young plants are grazed at emergence. Protect with cloches or collars until established.
