Growing Peas in Zone 4B

Peas are one of the first crops you can plant in spring. They fix nitrogen and enrich the soil.

Zone 4B has a short growing season — start seeds indoors when possible and use season-extending techniques like cold frames and row covers.

Top Growing Tips

• Plant as soon as soil can be worked — peas love cool weather
• Inoculate seeds with rhizobia for better nitrogen fixation
• Provide a trellis — even bush types benefit from support
• Harvest snap peas when pods are plump but still smooth
• Pull plants when production stops and plant warm-season crops in their spot

Companion Planting

Good companions: carrots, turnips, radishes, cucumbers, corn

Avoid planting near: onions, garlic

Harvest Timeline

55-70 days from seed
