Growing Corn in Zone 8A

Sweet corn needs space and warm soil but rewards with unbeatable fresh flavor.

Zone 8A enjoys a long growing season. You can often get two plantings of cool-season crops (spring and fall).

Top Growing Tips

• Plant in blocks of at least 4 rows for good pollination
• Soil must be 60°F+ for germination
• Heavy feeder — side-dress with nitrogen when plants are knee-high
• Silks turn brown when ears are ready (about 3 weeks after silking)
• Eat or process immediately — sugar converts to starch within hours

Companion Planting

Good companions: beans, squash, cucumbers, melons

Avoid planting near: tomatoes (both are heavy feeders)

Harvest Timeline

60-100 days from seed
