Quick Answer

Plant green bean seeds directly in the garden after your last frost when soil is 60°F+. Sow 1" deep, 3" apart. Bush beans produce in 50-60 days; pole beans in 60-70 days. Harvest every 2-3 days to keep plants producing.

Bush Beans vs Pole Beans

My recommendation: Grow both. Bush beans for a big early harvest, pole beans for steady picking all summer.

When to Plant

Green beans need warm soil. Don't rush them.

Soil temperature: Wait for 60°F minimum. Seeds rot in cold, wet soil.

Succession planting: Plant every 2-3 weeks until 8 weeks before first fall frost for continuous harvest.

How to Plant

Direct Sow (Recommended)

Beans don't transplant well. Direct sow in the garden.

1. Prepare soil — Loose, well-draining. Add compost if needed.
2. Plant seeds — 1" deep, 3" apart for bush, 4-6" apart for pole.
3. Row spacing — 18-24" between rows (bush), 36" for pole.
4. Water — Keep soil moist until germination (7-10 days).

Pole Bean Support

Set up support BEFORE planting:

• Teepee — 3-4 poles tied at top, 6-8 seeds per pole
• Trellis — Netting or string on a frame
• Single poles — 8 ft stakes, 3-4 plants per pole

Growing Conditions

Important: Don't over-fertilize with nitrogen. Beans partner with soil bacteria to create their own nitrogen. Too much nitrogen = lots of leaves, few beans.

Care During the Season

Watering

• Water at soil level, not on leaves (prevents disease)
• Consistent moisture during flowering is critical
• Mulch to retain moisture and suppress weeds

Weeding

• Beans have shallow roots—hand pull weeds carefully
• Mulch 2-3" deep to reduce weeding

Don't Touch Wet Plants

Avoid working around beans when leaves are wet. This spreads bacterial diseases.

Common Problems

Pests

Diseases

Other Issues

• No flowers: Too much nitrogen, not enough sun
• Flowers but no beans: Too hot (over 90°F), inconsistent water
• Tough beans: Harvested too late

Harvesting

When to Pick

• Snap beans: When pods are firm, seeds barely visible (pencil thickness)
• Before seeds bulge: Once you see seed bumps, beans get tough
• Check daily: Beans grow fast in warm weather

How to Pick

• Use two hands: hold stem, pull bean
• Don't yank—you'll damage the plant
• Harvest in morning when pods are crisp

Keep Picking

Critical: Harvest every 2-3 days. If beans mature on the plant, it stops producing new flowers.

Yield Expectations

One 4x8 raised bed can produce 15-20 lbs of beans per season with succession planting.

Best Varieties

Bush Beans

• Blue Lake 274 — Classic flavor, heavy producer
• Contender — Heat tolerant, early (50 days)
• Provider — Cold tolerant, good for early planting

Pole Beans

• Kentucky Wonder — Heirloom favorite, great flavor
• Blue Lake Pole — Same great taste, pole version
• Rattlesnake — Heat tolerant, purple-streaked pods

Storage

• Fresh: Refrigerate unwashed, use within 1 week
• Blanch and freeze: Best for long-term storage
• Canning: Pressure can only (low acid food)
• Drying: Let pods dry on plant for shell beans
