Lima Bean Seeds,
Christmas Pole

Plant Christmas Lima beans in the spring, about 3-4 weeks after the last frost, when the soil temperature has warmed to at least 60 F. The ideal temperature for growing Lima beans is 70-90 F. In colder climates, starting the seeds indoors 2-3 weeks before the last frost can give them a head start​.

Sow seeds directly into well-drained soil enriched with compost, planting them 1 to 1½ inches deep and spacing them 6 inches apart. Set up trellises or poles at planting time, as these vigorous vines can grow up to 10 feet tall and require support to thrive. Ensure they receive full sun for at least 6 to 8 hours a day​.

Lima beans need consistent moisture but should not sit in waterlogged soil. Water them regularly, especially during flowering and pod setting, and mulch around the plants to retain moisture. They do not require much nitrogen fertilizer due to their nitrogen-fixing ability, but adding compost or aged manure at planting time can help provide necessary phosphorus and potassium.

• Limas are a self-pollinating annual, but insects can cause accidental cross pollination between different Lima bean varieties. In order to prevent any chance of accidental crossing, separate different varieties for saving by 500 feet.
• To save seed, allow pods to dry and become brittle. The seeds inside should be very hard, so you cannot dent them with a fingernail.
• If expecting rain or frost, you can pull mostly dried pods and dry them further indoors.
• Store in a cool, dark, dry place.
