Dark Green Yard Long Beans grow long and flavorful dark green pods about 18-22 inches long on 6-10 foot vines! Just like green beans, but with more "bean flavor," meatier texture, and a thinner shape that makes for excellent stir-fries! Yard long beans are highly prized in Asian cuisine for their long, crisp texture, and ability to remain tender even when harvested at full length. Simply trim the ends and cut into short sections or keep intact for an impressive display. Dark Green Yard Long Beans are excellent for absorbing the flavors or sauces and spices, and can be used in place of green beans for an exotic flair! The beans are packed with protein, fiber, and essential vitamins, providing a nutritious and sustainable food source. Ideal for vertical gardening, Dark Green grows well on trellises, maximizing space and provides a lush, tropical aesthetic to your garden with minimal care take, ensuring an easy-to-grow crop that will continue to produce through the summer. Reddish-brown seeds.

Planting Instructions: Soil Preparation: Choose an area with heavy, well-draining soil that receives at least 6 hours of sunlight each day. Remove weeds, large rocks, and litter from the planting area. Leave small weeds and dead grass, they will enrich the soil when turned under. Spade or till the soil 8-12 inches deep. Loosening the soil will help the plant establish strong roots. Plants grows best in soil with lots of organic matter. You may optionally add fertilizer or organic material such as compost, leaves, or rotted hay to mix into the soil at this point. For small gardens, scatter 2-3 tablespoons of a low-nitrogen fertilizer evenly and work into the top 2-3 inches of soil for each hill or 2 foot by 2 foot planting area. For larger gardens, scatter 2-3 pounds of a low-nitrogen fertilizer for each 100 square feet of planting area. Work fertilizer or organic material into the soil and leave the surface smooth. Form rows of soil beds 4-6 inches high and at least 18 inches apart. This formation of ridges will help with drainage. Prepare 6-8 foot stakes, trellises, or fences to train yard long bean vines to climb as they establish. Planting: Yard long beans grow best in temperatures between 65F-85F. Direct-sowing is recommended. Plant yard long beans in the spring after all danger of frost has passed and the soil temperature reaches at least 60F. For fall crops, direct sow seeds outdoors 10-12 weeks before the first frost. If choosing to stake, plant yard long beans in hills about 3 feet apart in the row, placing a 6-8-foot stake in the center of each hill. Plant 3-4 seeds around the stake about 1 inch deep in the soil and tie plants to stakes as vines grow. If choosing to trellis or fence, plant 1 seed every 3-4 inches at the base of a 6-8-foot-tall trellis or fence. Cover seeds thinly with soil and water after planting. Planting Depth: 1 inch Within-Row Spacing: 3-4 inches, trellis Between-Row Spacing: 18-24 inches Care During the Season: Watering: Water the plants deeply, soaking the soil to a depth of 6-8 inches, once a week. If there is no rainfall, water 2-3 times a week. Water especially during flowering and pod formation. Sandy soils may need to be watered more often than heavy clay soils. Mulching around plants can help retain moisture. Weeding: Keeping plants weed-free improves production. If plowing or hoeing, do not dig deeper than 1 inch to prevent from cutting the feeder roots. Fertilizing: Once plants start forming pods, you may optionally apply 2 tablespoons of a low-nitrogen fertilizer around each hole, or 1-2 pounds per 100 square feet, without letting the fertilizer touch the plants. Water plants after fertilizing. Insecticides: Insecticides may be used to protect plants. Bt-based insecticides and sulfur are organic options that can be used for prevention. Sulfur also has fungicidal properties and helps in controlling many diseases. Before using a pesticide, read the label and follow cautions, warnings and directions. Diseases: If spots or mold appear, treat plants with an approved fungicide. Neem oil, sulfur, and other fungicides may be used. When using fungicides always follow label directions. Harvesting: Yard long beans are ready to harvest when they reach 12-18 inches in length but are still firm, tender, and slightly flexible, about 60-90 days after planting. If left too long, the pods become tough and fibrous, reducing their quality. To harvest, use pruning shears or scissors to cut the pods from the vine, or gently snap them off by hand while being careful not to damage the plant. Frequent harvesting - every 2-3 days - encourages the plant to produce more beans throughout the growing season.
