Growing Peanuts in Zone 5B

Peanuts are a quirky and rewarding warm-season crop. After the flowers bloom, ‘pegs’ bend down and push into the soil to form peanuts underground.

Zone 5B has a moderate growing season. Most crops do well here with proper timing around frost dates.

Top Growing Tips

• Needs 120-150 frost-free days — short-season growers should start early
• Plant in loose, sandy, well-draining soil for best development
• After flowering, mound soil around plants to cover the developing pegs
• Do not add extra nitrogen — like all legumes, they fix their own
• Pull entire plant and cure 2-3 weeks before shelling

Companion Planting

Good companions: sunflowers, corn

Avoid planting near: onions, garlic, brassicas

Harvest Timeline

120-150 days; harvest when leaves yellow and pods have papery skin
