How to Grow Peas in Containers
Pisum sativum
Fresh peas from the garden are a revelation - sweet, tender, and nothing like store-bought. These cool-season champions are perfect for spring container gardening, producing abundantly before summer heat arrives. With vertical growing, even small balconies can yield impressive pea harvests. Plus, they fix nitrogen to improve your soil for future plantings.
Best Pea Varieties for Containers
Sugar Snap (58 days)
The classic snap pea - thick edible pods with sweet peas inside. Vines reach 5-6 feet, requiring sturdy support. Eat whole, raw or cooked. Best for: fresh eating, maximum flavor.
Sugar Ann (52 days)
Compact snap pea - only 24-30 inches tall. Self-supporting or minimal support needed. Same sweet snap pea flavor. Early producer. Best for: small containers, no-trellis growing.
Oregon Sugar Pod II (60 days)
Best snow pea for containers - 30-inch plants with good disease resistance. Flat, sweet pods perfect for stir-fries. Pick before peas develop. Best for: Asian cooking, compact spaces.
Little Marvel (62 days)
Dwarf shelling pea - 18-inch plants packed with sweet green peas. No support needed. Excellent for freezing. Best for: traditional peas, small containers.
Common Problems and Solutions
Powdery Mildew
Solutions: Improve air circulation, water at soil level, choose resistant varieties. Common as weather warms - harvest remaining peas and compost plants.
Aphids
Solutions: Spray with strong water jet, apply insecticidal soap, encourage ladybugs. Check growing tips regularly where aphids cluster.
Heat Stress / No Pods
Solutions: Peas naturally decline in heat. Plant earlier, provide afternoon shade, harvest all pods when temperatures consistently exceed 75F.
Frequently Asked Questions
When should I plant peas?
Peas are cool-season crops that should be planted in early spring, 4-6 weeks before the last frost. They can germinate in soil as cool as 40F, though 60F is ideal. For fall harvest, plant 8-10 weeks before first frost. Peas don't do well in heat - production stops when temperatures regularly exceed 75F.
What's the difference between snap peas, snow peas, and shelling peas?
Snap peas (like Sugar Snap) have thick, edible pods with developed peas inside - eat whole. Snow peas (flat pods) are harvested before peas develop - eat whole. Shelling peas (garden peas/English peas) have inedible tough pods - shell out the peas inside. For containers, snap peas offer the best eating for the space.
Do peas need support to climb?
Most pea varieties benefit from support. Dwarf varieties (18-24 inches) can manage without, but still produce better with short support. Standard varieties (3-6 feet) definitely need trellising. Peas climb using tendrils - provide netting, string, or brushy twigs for them to grab.
Why aren't my peas producing pods?
Common causes: too hot (peas stop producing above 75F), planted too late in spring, too much nitrogen fertilizer (promotes leaves over pods), or too little sun (need 6+ hours). Peas are cool-season crops - once hot weather arrives, production naturally declines.
How big of a container do peas need?
Peas have shallow root systems and don't need deep containers. Use 8+ inch deep containers, planting peas 2-3 inches apart. A 5-gallon container can hold 6-8 pea plants. Long, shallow window boxes or grow bags work excellently. Provide support structure for climbing varieties.
Can I grow peas in summer?
Peas struggle in heat - most varieties stop producing when temperatures regularly exceed 75F. In hot climates, grow peas only in spring or fall. In cooler regions (Pacific Northwest, high elevations), summer peas may be possible with afternoon shade. Heat-tolerant varieties like 'Wando' extend the season slightly.
How often should I harvest peas?
Harvest snap and snow peas every 2-3 days - they quickly become tough and fibrous if left too long. Pick shelling peas when pods are plump but before peas turn starchy. Regular harvesting encourages continued production. Pea tendrils and shoots are also edible!
Do peas fix nitrogen like beans?
Yes! Like beans, peas form symbiotic relationships with Rhizobium bacteria that fix nitrogen from air into soil-usable form. After harvest, cut plants at soil level and leave roots to decompose, enriching your container soil for the next planting.
