Growing Lima Beans in Zone 4B

Lima beans need warmth and patience, but the buttery, creamy beans you get are far superior to any canned version.

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

• Need warm soil (65°F+) — cold soil causes rot, not germination
• Both bush (60 days) and pole (75-90 days) types available
• Shell while fresh for sweet, buttery flavor; let dry for dried beans
• Don’t overwater — they prefer slightly drier conditions than snap beans
• Harvest pods when beans are visible and plump inside but still green

Companion Planting

Good companions: corn, cucumbers, summer savory

Avoid planting near: onions, garlic, fennel

Harvest Timeline

60-90 days; harvest when pods are plump but still green
