Fresh sweetcorn harvested and eaten on the same day is a highlight to the year and a real moment to mark the transition from summer to autumn.
If growing sweetcorn in a polytunnel they may need a little help with pollination. Sweetcorn are pollinated by the wind instead of by insects. There doesn’t tend to be much wind in the tunnel so giving each plant a little shake can do the same job.
All the pollen is on the seed heads on the top of the plant. By shaking the plant, the pollen drops to pollenate the corn by landing on fine hairs growing from their tips. This will help you to have nice and full sweet corn instead of shrivelled, dry kernels.
