Germination & Seedling
10-14 daysSeeds sprout within 7-10 days. First true leaves emerge, plant is small with cotyledons visible.
Keep soil consistently moist but not waterlogged. Ensure soil temperature is at least 60°F (preferably 70°F+). Do not plant until soil has warmed thoroughly. Thin seedlings if overcrowded.
Vegetative Growth
20-25 daysPlant develops true leaves, stems elongate, and root system expands. Bush varieties remain compact; pole varieties climb or sprawl.
Provide support/trellis for pole varieties early. Keep soil evenly moist. Mulch to retain moisture and regulate soil temperature. Begin light feeding with balanced fertilizer.
Flowering
7-10 daysSmall white, pink, or purple flowers appear at leaf axils. Bees and other pollinators visit frequently.
Maintain consistent watering; flower drop can occur if stressed by drought or heat. Avoid high-nitrogen fertilizer. Do not disturb plants during flowering. Continue regular mulching.
Pod Development & Maturation
20-25 daysFlowers fade and pods begin forming, becoming fuller and plumper over time. Pods turn from green to a mature light or dark green color.
Continue regular watering without wetting foliage. Harvest pods regularly to encourage continued production. Monitor for pests and diseases. Reduce nitrogen to avoid excessive foliage.
Harvest
Ongoing, 2-3 weeks of peak productionPods reach full size, beans inside are plump but pods are still tender and green (for fresh eating). Seeds are easily visible as bumps on pod surface.
Pick pods when they snap easily and beans inside are fully developed but pods still tender. Handle gently to avoid damaging plants. Continue harvesting to extend production through season.

Harvest Tips
For fresh eating, harvest when pods are full-sized, tender, and bright green—usually 60-70 days after planting. Snap or cut pods carefully from the plant, or pinch beans out directly. Pick regularly (every 2-3 days) to encourage continuous production. For dry beans, leave pods on plant until fully mature and brown, then shell and store in cool, dry place. Harvest before hard frost.
Fun Facts
- 🌱 Baby lima beans are actually the same species (Phaseolus lunatus) as large lima beans—'baby' refers to both the smaller pod size and the immature bean size, not a different variety.
- 🌱 Lima beans are native to South America and were cultivated by the Inca civilization over 7,000 years ago; the name 'lima' comes from the capital of Peru.
- 🌱 A single lima bean plant can produce 50-100 pods over its growing season, making them one of the most prolific vegetable crops for home gardeners.
