Broad beans, or fava beans, have long and flat seeds that are stripped from the pods and eaten. The relon broad bean variety is prized for its large pods that have up to ten beans inside. They grow on four foot vines and have pods over a foot long. Relon beans are a cool-season crop that are planted in early spring and reach maturity during early summer. They may also be planted in fall as a winter crop in areas with mild winters and no freezing.
Prepare a full-sun, well-draining garden bed in spring as soon as the soil dries out enough to work. Apply a 2-inch layer of mature compost to the bed and till it in to an 8- to 10-inch depth to aid drainage and soil quality.
Sow relon seeds two inches deep and space plants eight to 10 inches apart. Plant in rows that are two feet apart.
Water as needed to keep the soil moist but not soggy. Spring crops require minimal watering as the ground is still moist from winter, while fall crops may require once a week irrigation providing up to two inches of water per plant.
Apply a 2-inch layer of organic mulch around each plant once the seeds germinate, approximately seven to 14 days after planting. Mulching preserves soil moisture as well as preventing weeds.
Harvest pods while they are still green but are rounded out with the beans inside. Relon varieties are harvest-ready approximately 90 days after sowing.
