Growing Sweet Peas in Zone 6B

Sweet peas are fragrant climbing flowers that bloom in cool weather — a cottage garden essential.

Zone 6B has a moderate growing season. Most crops do well here with proper timing around frost dates.

Top Growing Tips

• Soak seeds overnight before planting for faster germination
• Plant very early spring (or fall in mild climates) — they love cool weather
• Provide a trellis or netting — they climb 6-8 feet
• Cut flowers daily to keep plants blooming
• NOT edible — sweet peas are toxic if ingested (unlike garden peas)

Companion Planting

Good companions: other cool-season flowers, beans (share trellises)

Avoid planting near: none — but keep separate from edible peas to avoid confusion

Harvest Timeline

Flowering in 50-65 days from seed; pick daily for longest bloom season
