Fall / Winter ยท Beginner ยท Phoenix / East Valley, AZ
Snap peas and snow peas are one of the most satisfying crops in the Phoenix fall garden โ and one of the few you'll be harvesting in January while eating fresh-picked pods right off the vine. Sweet, crunchy, and remarkably easy to grow if you get the timing right.
Peas are strictly a cool-season crop. They germinate best below 70ยฐF and stop producing once temps consistently hit 80ยฐF. In Phoenix, our October-through-February cool season is their sweet spot.
Direct sow peas in October โ ideally early to mid-October. This gives plants enough time to establish before the coldest December nights slow growth, and they'll be hitting peak production in January and February when our weather is mild and beautiful.
November plantings can work but produce a shorter, less productive harvest. Avoid planting after mid-November.
Most snap and snow peas climb 4โ6 feet tall. Install your trellis before planting so you don't disturb roots later. A simple option: pound in two stakes and run horizontal strings of twine every 6 inches, or hang netting between the stakes. Peas grab the trellis with thin tendrils โ they're self-climbing once they find something to grab.
Direct sow seeds 1 inch deep, 2โ3 inches apart, along the base of your trellis. Peas don't like to be transplanted โ always sow directly into the garden. They germinate in 7โ14 days. Thin to 4โ6 inches apart once established.
Soaking seeds overnight before planting speeds germination slightly.
Like beans, peas fix their own nitrogen, so don't over-fertilize. A compost amendment before planting is sufficient. Water consistently but don't overwater โ peas are susceptible to root rot in waterlogged soil. In Phoenix's cool winter weather, watering every 3โ4 days is usually adequate.
Harvest snap peas when pods are plump, bright green, and the peas inside are visible but before the pod gets tough or stringy. Taste test frequently โ the best time to harvest is when they're sweetest. Cold nights actually increase sugar content, so January peas are at their peak.
Pick every 2โ3 days during peak production to keep plants producing. Leaving overmature pods signals the plant to stop flowering.
