How to Grow Beans: From Snap to Dry, a Complete Guide

Green beans are grocery-store staples—so why grow your own? First, they’re easy and quick, perfect for beginners. Second, homegrown unlocks a world of variety: gourmet favorites you’ll never find at the market.

For best results, especially in containers or new beds, seek seeds inoculated with rhizobium bacteria to fix nitrogen.

Bean types.
Snap beans (string/green beans): traditionally long green pods; also yellow (wax), purple, multicolored. Bush (1–3 ft, shorter season) vs. pole (vines to 15 ft). Filet beans/haricots verts: thin, harvest young.
Shelling beans (“shellies,” horticultural/gourmet flageolet): dry beans harvested green and shelled.
Dry beans: pinto, kidney, navy, cannellini, plus esoteric varieties. Pods shatter on plant, then shelled and stored.
Lima beans: polarizing. Look like snap beans (bush/pole), slower, must shell. Eat green or dried.
Soybeans/edamame: not true beans but grown similarly. Fuzzy pods on bushes; great protein. “Edamame” = soybean, shelled beans, or the dish.
Scarlet runner beans: primarily ornamental flowering vine; young beans (to 3 in.) edible.

When to plant: Soil 60–70°F (15.5–21°C); seeds rot in cold, damp soil.
Days to maturity: Snap 45–80; shelling 70–80; dry 85–100; lima 65–100; soy 65–95.
Light: Full sun.
Water: Moist but not soggy after emergence.

• Shelling: Borlotto, Chevrier, flageolet, French horticultural, Great Northern white
• Dry: shelling types plus Aztec Dwarf White, European Soldier, Hutterite Soup, Jacob’s Cattle, Kenearly Yellow Eye, New Mexico Appaloosa
• Lima: Christmas, Fordhook 242, Henderson Bush (short), King of the Garden
• Soy: Butter beans, Early Hakucho, Envy, Midori Giant
• Scarlet runner: Painted Lady Improved, Scarlet Emperor

Planting and care. Loose, well-drained, moist soil; shallow roots need no deep tilling. Sow 1 in. deep (lima shallower), 1–3 in. apart, rows 2–3 ft apart. Water at emergence; keep moist. Fertilize at growth start and again at bean formation. Mulch at 6 in. tall.

Pole beans need support: single pole, trellis, grid, tepee, wall/fence. Install before planting; train vines at 6 in. Containers: ≥8–10 in. deep (pole need more), 12 in. wide, supports in place first.

Pests: aphids, beetles, spider mites, whiteflies. Row covers for young bush beans. Diseases: downy mildew, mosaic, rust.

Harvest. Snap: pick every 2 days once mature to sustain production. Dry: wait for pods to dry/shatter, shell, dry, store. Shelling: 2–3 weeks before dry stage. Lima/soy: when ripe.
