When to Plant:Sow seeds directly outdoors in late spring after all danger of frost has passed and thesoil temperature is consistently above 65°F(preferably closer to 70-75°F for optimal germination).
Location:Choose a sunny spot that receivesfull sun(at least 6 hours of sunlight daily) and has loose, well-draining soil.
Sowing Method:Direct sowing is recommended as lima beans do not transplant well.
Depth and Spacing:Plant seeds about1 inch deepand 4 to 6 inches apart, in rows 18 to 36 inches apart.
Support:As a bush variety, Henderson limas are compact (growing 18-24 inches tall) anddo not require a trellis or support.
Care and Maintenance
Watering:Provide consistent moisture, ensuring the plants get about1 inch of water per week, especially during the flowering and pod formation stages. Water from below to avoid soaking the leaves and potentially spreading disease.
Soil:They prefer well-drained, nutrient-rich, loamy soil with a pH between 6.0-6.8. Avoid using nitrogen-heavy fertilizers, as beans are light feeders and can fix their own nitrogen in the soil.
Weeding:Be careful not to disturb the shallow roots of the plants when weeding, especially before the plants mature and shade the soil naturally.
Pests/Diseases:The variety is generally hardy and disease-resistant. Common pests like Mexican bean beetles can be managed with insecticidal soap. Proper spacing and air circulation will help prevent fungal diseases.
Harvesting
Days to Maturity:Plants typically mature and are ready for harvest in60 to 70 daysfrom germination.
For Fresh Eating:Pick the pods when they are well-filled, firm, and still a light green color. Prompt, consistent picking will encourage the plant to produce more pods over a longer season.
For Dry Storage:Allow the pods to remain on the plant until they become fully dry, brown, and brittle, and the seeds rattle inside.
Preservation:The beans are excellent for canning, freezing, or drying.
