How to Grow Peas in Pots (A Cool-Season Crop)
Grow peas in pots or on a balcony: fall and spring sowing, depth, netting to climb, watering and when to harvest the pods at their sweetest point.
In this article
Peas are the perfect balcony legume for the cool seasons: they grow fast, look pretty with their tendrils and pods, and freshly picked they're so sweet that many never make it to the kitchen. Like all legumes, they fix nitrogen and need little feeding. Here's how to grow them in pots.
| Fact | Peas in pots |
|---|---|
| Pot depth | 8-10 inches |
| Sowing | Direct, 1 inch, fall or late winter |
| Temperature | 50-65 °F (cool season) |
| Support | Netting from the start (climbing) |
| Light | 5-6 h of sun |
| Harvest | Pods full but tender |
A cool-season crop
This is the key to success: peas hate heat. Sow them in fall (in mild climates) or late winter and early spring. They sprout in the cold and crop best at 50-65 °F. In strong heat they stop flowering and the plant burns out.
Varieties for pots
- Dwarf or bush: 16-24 inches, barely need support. The easiest for pots.
- Climbing: reach 5-6 feet and need netting; they produce more and for longer.
- Snap/snow peas (mangetout): you eat the whole tender, sweet pod. Very rewarding.
Pot and sowing
- At least 8-10 inches deep; a long planter works perfectly.
- Soil with good drainage and some compost.
- Sow directly, about 1 inch deep and 3-4 inches apart.
- They germinate in 7-14 days. They dislike transplanting, so skip the seed trays.
Support, sun and water
- Netting or twigs from the start: peas climb with tendrils and need something to grab. Set it up at sowing time.
- Sun: 5-6 hours is enough; in warm climates they appreciate some afternoon shade.
- Water: keep the soil moist, especially during flowering and pod fill. If it dries out, the pods come out small.
Harvest at peak sweetness
Pick the pods when they're full but still tender and a bright green. As with beans, harvesting often pushes the plant to make more. Snow peas are picked flat, before the seeds bulge. Pea sugar turns to starch within hours, so eat them as soon as you can.
Common problems
- Powdery mildew (white dust on leaves) in heat and stagnant air: improve airflow; see our powdery mildew guide.
- Aphids on shoots: wash off with water or insecticidal soap.
- Few pods: usually too much heat or too little water.
