Green Lentil
Lens culinaris var. viridis
vegetableGreen lentils are a cool-season legume crop that produces small, lens-shaped seeds in protective pods. They are prized for their earthy flavor, firm texture after cooking, and high nutritional value including protein and fiber. Green lentils are more heat-tolerant than red lentils and retain their shape better during cooking.

Germination & Emergence
1-2 weeksSoil temperature should be 50-60°F minimum; seedlings emerge in 7-14 days with two small cotyledons
Keep soil consistently moist but not waterlogged. Thin seedlings if overcrowded. Ensure good air circulation to prevent damping off.
Vegetative Growth
4-6 weeksPlant develops compound leaves and bushy branching structure; grows 12-20 inches tall
Monitor for weeds and remove by hand-hoeing to avoid root damage. Apply balanced fertilizer at 4-6 weeks if soil is poor. Mulch lightly to retain moisture.
Flowering
2-3 weeksSmall white, pink, or pale purple flowers appear in clusters along stems; typically occurs 6-8 weeks after planting
Maintain consistent moisture during flowering for better pod set. Avoid high nitrogen fertilizer which delays flowering. Provide stakes or small trellis support if plants become leggy.
Pod Development & Maturation
3-4 weeksFlowers develop into small green pods containing 1-2 lentil seeds each; pods gradually mature and turn brown-tan
Continue regular watering until pods mature. Reduce watering in final 2-3 weeks as plants dry down. Watch for pest damage and diseases on developing pods.
Harvest Readiness
1-2 weeksPods dry and turn pale brown; stems become brittle and dry; seeds rattle inside pods when shaken
Stop watering 1-2 weeks before harvest. Allow plants to dry on the plant if weather permits. Cut plants at soil level to prevent re-sprouting and facilitate drying.

-
Increase humidity and water frequency; strong water spray; use sulfur dust or miticide if severe

Uses
Soups, stews, and salads
CulinaryGreen lentils hold their shape beautifully when cooked and have a mild, slightly peppery flavor. They are ideal for hearty soups, French lentil salads, and sides that benefit from a firm texture. [source]
High-protein grain substitute
CulinaryLentils provide approximately 9g of protein per cooked cup and are rich in essential amino acids. They serve as an excellent plant-based protein for vegetarian and vegan diets. [source]
Nutritional and digestive health
MedicinalGreen lentils are rich in dietary fiber (8g per cooked cup), polyphenols with antioxidant properties, and resistant starch that supports gut health. Traditionally used to support sustained energy and digestive regularity. [source]
Sustainable crop and soil improvement
HouseholdAs a nitrogen-fixing legume, lentils naturally improve soil fertility for subsequent crops, reducing the need for synthetic nitrogen fertilizers. Growing lentils supports sustainable agriculture and regenerative farming practices. [source]
Pollinator and beneficial insect support
WildlifeLentil flowers attract bees, hoverflies, and other beneficial insects during the flowering stage. Growing lentils supports pollinator populations and encourages natural pest control in the garden. [source]

Harvest Tips
Harvest when 80-90% of pods have turned brown and stems are dry and brittle, typically 100-120 days after planting. Cut plants at soil level with a sickle or harvest knife rather than pulling. Lay cut plants on a tarp in the sun for 2-3 weeks to fully dry, then thresh by beating pods or running through a grain mill to extract seeds. Separate seeds from chaff using a winnowing basket or fan. Store fully dried lentils in airtight containers in a cool, dry location.
