Sweetcorn Seeds 'Mirai Picnic' F1 - 20 Seeds - Marshalls Garden

Yes, 'Mirai Picnic' can be grown in large containers, but ensure they are deep enough and provide adequate space for pollination. Growing in blocks is still recommended.

The tassels at the end of the cob should have turned brown and dry. When you pierce a kernel with your fingernail, it should release a milky-white liquid, not a clear one.

Sweetcorn is wind-pollinated. If different varieties are planted close together, they can cross-pollinate, leading to a reduction in the 'supersweet' quality of 'Mirai Picnic' or other undesirable traits.

'F1' indicates that these are first-generation hybrid seeds. F1 hybrids generally offer improved vigor, uniformity, and yield compared to open-pollinated varieties.

Sweetcorn requires consistent moisture, especially during silking and kernel development. Aim to keep the soil evenly moist but not waterlogged. Mulching helps retain soil moisture.

While wind is necessary for pollination, very strong winds can damage the plants. Planting in blocks and providing some shelter can help. Its compact nature makes it slightly more resilient than taller varieties.

Ensure consistent moisture and warmth (18-21°C for indoor sowing). Check seed depth; too deep can hinder germination.

This is often due to inadequate pollination. Ensure plants are grown in blocks and not isolated from wind, which helps carry pollen. Avoid cross-pollination with other corn varieties.

Protect young plants with horticultural fleece. Delay outdoor sowing or planting out until the risk of frost has passed.

Check for pests at the root or stem base. Ensure good drainage to prevent waterlogging, which can cause root rot.
