Golden Bantam Sweetcorn problems — and how to fix them
Golden Bantam Sweetcorn (Zea mays) 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.
Poor pollination / blank cobs
Result of growing in a single row. Always plant in square blocks of at least 4×4 plants to allow reliable wind pollination.
Badgers and squirrels
Wildlife damage to ripening cobs is common. Protect with netting or fleece around the cob-bearing section of stems.
Smut (Ustilago maydis)
Swollen, grey-black galls replace kernels. Remove and dispose of affected cobs immediately; do not compost.
Aphids
Colonies on tassels and leaves; generally cosmetic but can spread viruses. Encourage beneficial insects; use insecticidal soap if severe.
Slugs on seedlings
Young transplants are vulnerable. Protect with grit or copper barriers until plants are well established.
