Growing Organic Black Yard Long Beans in the Vegetable Garden
Direct sow yard long bean seeds 1 inch deep once soil temperatures are reliably above 65 F, spacing seeds 3 to 6 inches apart at the base of a sturdy trellis, fence, or pole structure. These vines grow tall and vigorously, so set up strong support at planting time, since it's difficult to add a trellis once the plants are established.
Yard long beans thrive in hot, humid conditions and need consistent moisture, especially once vines begin flowering and setting pods. Water at the base of the plant rather than overhead to help prevent disease, and harvest often to keep the vines productive throughout the season.
Harvesting Organic Black Yard Long Beans
Despite the name, pods are best picked well before they reach a full yard in length, generally between 10 and 20 inches, while they're still tender and the seeds inside haven't begun to bulge. Harvest every couple of days once vines start producing, since pods left too long on the vine become tough, fibrous, and less flavorful. Use two hands to pick, holding the vine steady while pulling the pod free.
About Organic Black Yard Long Bean Garden Seeds
Yard long beans, also known as asparagus beans, originated in Asia and remain a staple ingredient throughout Asian cuisine, especially in stir-fries.
Unlike common snap beans, this variety thrives in hot, humid summer conditions that would cause poor pod set in many other beans, making it a good choice for gardeners in warmer climates.
The black seeds are a distinguishing feature of this variety, and the vines are known for vigorous, high-yielding growth once established.
Tips From Our Gardeners
Don't wait for a full yard. The pods are tastiest and most tender well before they reach their namesake length, so start checking the vines regularly once pods begin to form.

| Plant Spacing: | 3-6 inches |
| Row Spacing: | 24-36 inches |
| Plant Height: | 96-144 inches |
| Growth Habit: | Vining |
| Soil Preference: | Beans prefer well-draining, loose, loamy soil with a pH of 5.5-7.5. As light feeders and nitrogen-fixing legumes, beans do not require nitrogen-heavy fertilizers. |
| Temperature Preference: | Warmer, 75-90 F |
| Light Preference: | Full Sun |
Other
| Direct Sow: | Yes, direct sow once soil temperatures are reliably above 65 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 self-pollinate because their flowers contain both male and female parts, unlike many other fruit and vegetable plants. While they self-pollinate, having a variety of pollinators and flowers around can improve yields by increasing the likelihood of pollination. |
| Snap or Shell Bean: | Snap - Snap beans have a fleshy edible pod. Snap beans are also commonly called 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 you can also grow them in containers with the right support. |
| Plant Width: | 12-24 inches |
| Deer Resistant: | No |
| Germination Temperature: | 65-90 F |
| Pests and Diseases: | More resistant to bean beetles than most snap bean varieties, and tolerant of a wide range of soils. Still susceptible to aphids and spider mites. Look for signs of chewing, curling leaves, eggs on the undersides of leaves, and leaf discoloration. |
