Growing Dark Green Yard Long Beans in the Vegetable Garden
To begin planting Dark Green Yard Long Beans, direct sowing is typically recommended, as these beans establish best when planted directly in warm soil. Seeds should be sown once the soil temperature reaches at least 70 F, usually about two to three weeks after the last frost. Plant seeds 1 inch deep, placing each seed about 4-6 inches apart. For row planting, keep rows spaced 24 inches apart, allowing air circulation and sunlight access to each plant. This initial spacing is essential for healthy vine development, which is a characteristic growth habit of this pole bean variety.
Once the seeds have sprouted and the plants begin to establish, setting up a sturdy trellis or support system is essential. Dark Green Yard Long Beans are vigorous climbers, reaching heights of 8-10 feet, so they will require a tall and robust structure. A vertical trellis helps keep the vines off the ground, improving air circulation and reducing the risk of fungal infections, especially in humid conditions. Keep the soil consistently moist, watering deeply at the base of the plant to encourage strong root growth. It’s best to water in the morning to allow any surface moisture to evaporate during the day, further reducing disease risks.
Harvesting Dark Green Yard Long Beans
Harvesting Dark Green Yard Long Beans typically begins around 70 days after planting. Beans should be picked when they are 12-18 inches long and still tender, which is when they offer the best flavor and texture. It’s important to harvest them before they become tough or overly mature. Use scissors or a sharp knife to cut the pods from the vine to avoid damaging the plant, as rough pulling can disrupt the growth of additional pods. With regular harvesting, the plant will continue to produce, providing a consistent supply of fresh beans throughout the season.

| Bean Sub-Type: | Asian - Asian beans encompass a wide spectrum of bean varieties, either originating from Asia or being especially popular in Asian cultures. Specialty - There are many subcategories of beans, and in the interest of simplifying what would be an overwhelming number of bean varieties, we group them as 'specialty'. These include but are not limited to yardlong beans, winged beans, hyacinth beans, sword beans, asparagus beans, adzuki, mung, garbanzo, and others. |

| Days to Maturity: | 70 |
| Days to Germination: | 5-10 |
| Seeding Depth: | 1 inch |
| Plant Spacing: | 4-6 inches |
| Row Spacing: | 24 inches |
| Plant Height: | 60-108 inches |
| Growth Habit: | Vining |
| Soil Preference: | Beans prefer well-draining, nutrient-rich, loamy soil with a pH of 6.0-6.8. As light feeders and nitrogen-fixing legumes, beans do not require nitrogen-heavy fertilizers. |
| Temperature Preference: | Warmer (70-85 F). |
| Light Preference: | Full Sun |
Other
| Direct Sow: | Yes, direct sow when soil temperatures are reliably above 60 F. Planting with an inoculant may increase yields, but is certainly not required for a successful grow. |
| Start Indoors: | Not Recommended. Beans grow best without any root disturbance. We recommend direct sowing instead of transplanting. |
| Bean Pollination: | Beans are self-pollinating as they contain both the male and female parts within their flowers, unlike other fruit and vegetable plants. While they are self-pollinating, having a variety of pollinators and flowers around will improve yields by ensuring the greatest chances for pollinating events to occur. |
| Snap or Shell Bean: | Snap - Snap beans have a fleshy edible pod. Snap beans are also commonly referred to as string beans or green beans (though not all snap beans are green). They are called snap beans because they make a snapping sound when you break them in half. |
| Pole or Bush Bean: | Pole - Pole beans are vining-type plants that put out runners that grow very long or tall. Pole beans are so-called because they require a trellis, support, or wait for it… a pole. Pole beans require more effort than bush beans but may also be grown in containers with the right support. |
| Plant Width: | 12-18 inches |
| Growth Speed: | Mid - Ready for harvest around 66-86 days. |
| Deer Resistant: | No |
| Germination Temperature: | 70-90 F |
| Pests and Diseases: | Beans are susceptible to beetles, aphids, spider mites, and cutworms. Look for signs of chewing, curling leaves, eggs on the undersides of leaves, and leaf discoloration. Keeping your bean plants clean from dust build-up and surrounded by a variety of plants to help deter and prevent pest damage. Beans are also susceptible to powdery mildew, bean blight, rust, and root rot. Maintain a regular watering schedule that avoids overly saturated soil. The roots need adequate time to air out between watering. This will also help prevent common fungal and bacterial diseases from developing. Good air circulation and applying water to the ground rather than the leaves will help maintain healthy bean plant growth. |

| Bean Use: | The Dark Green Yard Long Bean is used in stir-fries, soups, stews, salads, and as a crunchy side dish, often seasoned with garlic, spices, or sauces. |
