Germination & Seedling
2-3 weeksSeeds sprout within 7-10 days. Cotyledons emerge, followed by true leaves. Plants are delicate and low-growing.
Keep soil moist but not waterlogged. Thin seedlings to proper spacing. Protect from wind and frost.
Vegetative Growth
4-6 weeksPlants develop compound leaves and branching stems. Bushy growth 12-16 inches tall. Root nodules form for nitrogen fixation.
Allow rhizobial nodules to establish; avoid excess nitrogen fertilizer. Water moderately. Weed carefully to avoid damaging shallow roots.
Flowering
3-4 weeksTiny white, pink, or lavender flowers appear along stems in clusters. Flowers are self-fertile and insect-pollinated.
Continue moderate watering. Do not add nitrogen fertilizer. Attract pollinators by avoiding pesticides.
Pod Development & Maturation
4-5 weeksFlowers fade and small pods form containing 1-2 seeds. Pods turn from green to brown as they mature and dry.
Reduce watering gradually. Watch for pest damage. Plants are ready to harvest when pods rattle and turn completely brown.
Harvest & Curing
1-2 weeks curingPlants die back, stems become brittle, and pods are fully dry. Seeds are hard and cannot be dented by fingernail.
Harvest when 80-90% of pods are brown. Pull entire plants or cut at soil line. Dry in warm location for 1-2 weeks before threshing.

Harvest Tips
Harvest when 80-90% of pods have turned brown and plants are completely dry (usually late summer to early fall). Pull entire plants by the roots or cut at soil level with a sickle. Lay plants in a dry location for 1-2 weeks to cure fully. Thresh by beating pods with a flail or running over them to separate seeds from pods. Winnow to remove chaff. Store dried lentils in cool, dry conditions in sealed containers for up to 1 year.
