Know Your Pea Types
Three Delicious Options for Your Garden
Sugar Snap Peas
Eat WholePlump, crunchy pods with fully developed peas inside. Eat the entire pod raw or cooked. The most popular type for snacking.
Snow Peas
Eat WholeFlat, tender pods harvested before peas develop fully. Delicate texture, slightly sweeter than sugar snaps. Classic in Asian cuisine.
Shelling Peas
Shell FirstGrown for the peas inside; pods are too tough to eat. Classic "English peas." Sweetest flavor but most work to prepare.
Pea Planting Timeline
Two Windows for Santa Cruz Gardens
Spring Window (Main Season)
Plant: January through March
Harvest: April through June
Main pea season. Plant as soon as soil can be worked. Peas tolerate light frost and prefer cool weather.
Fall Window (Bonus Crop)
Plant: Late August through October
Harvest: November through December
Less common but works well in mild Santa Cruz climate. Often has fewer mildew problems than spring.
Sugar snap peas and snow peas are perfectly suited to Santa Cruz County's cool, foggy climate. While gardeners in hotter regions struggle to grow peas before summer heat shuts them down, our moderate temperatures let peas thrive for extended seasons in both spring and fall.
This guide covers everything specific to growing these edible-pod peas in our microclimates. You will learn optimal planting times, the best varieties for coastal conditions, and how to maximize your harvest in our unique growing environment.
If you have avoided peas because you thought they were fussy or low-yielding, Santa Cruz is the place to reconsider. Our climate is ideal for these crops, and the difference between store-bought and homegrown peas is dramatic enough to make garden space worthwhile.
Understanding Edible-Pod Peas
Sugar snap peas and snow peas are both eaten pod and all, but they differ in how they are harvested and used.
Sugar Snap Peas have thick, crunchy pods harvested when seeds are plump and visible. Both the pod and seeds are sweet and tender. They are eaten raw, stir-fried, or lightly steamed. The most versatile type for fresh eating.
Snow Peas have flat, tender pods harvested when seeds are barely visible as tiny bumps. Pods should be nearly translucent when held to light. Primarily used in stir-fries and Asian cooking where their delicate crunch is prized.
Both differ from shelling peas (English peas), where only the seeds are eaten and pods are discarded. Shelling peas work well here too but are covered in our main Growing Beans and Peas guide.
Why Santa Cruz is Ideal for Peas
Peas are cool-season crops that stop producing when temperatures consistently exceed 75 degrees F. Hot weather causes blossoms to drop without setting pods and existing pods become tough and starchy.
Santa Cruz County's coastal influence keeps summer temperatures moderate, extending the pea season significantly compared to inland California. Coastal gardeners can often harvest peas into June, while fall plantings produce well into December in mild years.
The fog that frustrates tomato growers is perfect for peas. Cool, moist conditions promote steady growth and extended production without the heat stress that limits peas elsewhere.
When to Plant Peas in Santa Cruz
Timing is the most important factor for successful peas. Plant too late in spring and heat ends production early. Plant too late in fall and cold weather slows growth before plants mature.
Spring Planting
Coastal areas (Westside Santa Cruz, Live Oak, Aptos, Capitola): Plant from late January through mid-March. The fog belt's cool summers mean you can often push planting into early April and still get good production.
Inland valleys (Scotts Valley, Soquel hills): Plant from mid-January through early March. Warmer summer temperatures end production earlier than on the coast.
San Lorenzo Valley (Boulder Creek, Ben Lomond): Plant from February through mid-March in sunny spots. Higher elevation brings cooler nights but also more temperature variation.
Under redwoods (Felton, Ben Lomond canyons): Plant from February through March. Shade keeps conditions cool, which peas appreciate, though reduced light may limit yields.
Pajaro Valley (Watsonville): Plant in January through February. Warmer temperatures end the spring pea season earlier here than in cooler microclimates.
Fall Planting
Fall peas often outperform spring plantings in Santa Cruz because they mature during cooling weather rather than racing against warming temperatures.
All microclimates: Plant from late August through October. Earlier plantings (late August to early September) establish before days shorten significantly and often produce the heaviest crops. October plantings still produce but may grow more slowly.
Fall peas typically harvest from November through December, with production continuing into January in mild coastal winters.
Direct Sow vs. Transplant
Peas prefer direct sowing but tolerate transplanting better than beans. If you want a head start, sow seeds in deep cell packs 3 to 4 weeks before your outdoor planting date. Transplant carefully with minimal root disturbance.
In very wet winters, starting peas in containers and transplanting when soil drains better can prevent seed rot.
Best Varieties for Santa Cruz
Coastal Santa Cruz's extended cool season lets you grow most pea varieties successfully. However, some perform better than others in our specific conditions.
Sugar Snap Peas
'Sugar Snap' (Original) (58-70 days)
The original sugar snap, developed in the 1970s. Tall vines (5 to 6 feet) require sturdy support but produce abundantly over a long period. Excellent sweet flavor and satisfying crunch. Some susceptibility to powdery mildew, which is worth monitoring in humid coastal conditions.
Best for: Gardeners with space for tall trellises, maximum production
'Super Sugar Snap' (60-65 days)
Improved version with better disease resistance, including powdery mildew tolerance. Similar height and production to the original but holds up better in coastal humidity. Many gardeners consider this the best overall sugar snap.
Best for: Coastal fog belt, disease-prone gardens
'Cascadia' (60-70 days)
Bred specifically for the Pacific Northwest (similar climate to coastal Santa Cruz). Compact vines (2 to 3 feet) need only light support. Excellent resistance to powdery mildew and pea enation virus. Slightly smaller pods than taller varieties but reliable production.
Best for: Small gardens, container growing, disease resistance priority
'Sugar Ann' (56-60 days)
Compact bush type (18 to 24 inches) that needs no support. Earliest sugar snap to mature. Pods are smaller than climbing types but flavor is excellent. Good for containers and small spaces.
Best for: Containers, small spaces, earliest harvest
Snow Peas
'Oregon Sugar Pod II' (60-70 days)
The standard snow pea for Pacific coastal gardens. Compact vines (2 to 3 feet) with excellent disease resistance including powdery mildew. Large, flat pods with outstanding flavor. Widely adapted and reliable.
Best for: All microclimates, disease resistance, best overall choice
'Oregon Giant' (60-70 days)
Extra-large pods (4 to 5 inches) on 3-foot vines. Good disease resistance. The big pods are easier to spot for harvest and impressive in stir-fries.
Best for: Large pod preference, moderate space
'Mammoth Melting Sugar' (65-75 days)
Tall vines (4 to 5 feet) with very large, sweet pods. More susceptible to disease than Oregon types but excellent flavor when conditions cooperate. Better suited to fall than spring (less mildew pressure).
Best for: Fall planting, flavor priority
'Dwarf Grey Sugar' (60-70 days)
Compact plants (2 to 3 feet) with beautiful purple flowers. Edible shoots are a bonus (pea tendrils are a gourmet green). Good disease resistance and reliable production.
Best for: Ornamental value, pea shoot harvest, smaller gardens

Planting and Growing
Soil Preparation
Peas prefer well-drained soil with moderate fertility. They do not need heavy feeding since they fix their own nitrogen. Excessive nitrogen actually promotes foliage at the expense of pods.
Work compost into your planting area to improve soil structure and drainage. If your soil is heavy clay (common in parts of Santa Cruz), consider raised beds for better drainage.
Peas prefer slightly alkaline to neutral pH (6.0 to 7.5). Most Santa Cruz soils fall within this range. Gardens under redwoods may need lime to raise pH from the naturally acidic conditions.
Planting Method
Sow seeds 1 to 2 inches deep and 2 to 3 inches apart. Plant in double rows 6 inches apart with 3 feet between double rows. This arrangement provides mutual support and efficient use of trellis structures.
For fall planting in warm soil, soak seeds overnight before planting to speed germination. This is optional but helpful when soil temperatures are at the upper end of peas' tolerance.
Consider inoculating seeds with rhizobia bacteria before planting, especially if you have not grown peas or beans in that spot recently. Inoculant is inexpensive and available at San Lorenzo Garden Center and other local nurseries.
Support Structures
Even "short" pea varieties benefit from some support. Pea tendrils grab anything they touch, and providing support keeps plants upright, improves air circulation (reducing disease), and makes harvest easier.
For short varieties (under 3 feet): Twiggy branches pushed into the soil, a low string trellis, or wire fencing laid horizontally and supported on short stakes all work well.
For tall varieties (3 to 6 feet): Use sturdy trellises similar to pole bean supports. Pea netting with 4 to 6 inch openings works excellently and can be composted with plant debris at season's end.
Install supports at planting time. Adding them after peas have started growing inevitably damages tender vines.
Watering
Peas need consistent moisture, especially during flowering and pod development. Water stress during this period causes blossom drop and reduces yield.
Water deeply but infrequently, allowing the top inch of soil to dry between waterings. UC Master Gardeners recommend about 1 inch of water per week during active growth, though coastal fog reduces evaporation and your peas may need less than inland gardens.
Mulch around plants (keeping mulch away from stems) to conserve moisture and moderate soil temperature.
Fertilizing
Peas fix their own nitrogen and need little fertilization. A light application of balanced fertilizer at planting is sufficient. Avoid high-nitrogen fertilizers during growth, which promote lush foliage but reduce pod production.
If plants show pale leaves or slow growth, a light side-dressing of compost or a balanced organic fertilizer can help. But symptoms of nitrogen deficiency in peas often indicate other problems (compacted soil, poor drainage, lack of rhizobia) rather than actual nitrogen shortage.
Maximizing Your Harvest
Harvest Timing
Correct harvest timing makes the difference between mediocre and outstanding peas.
Sugar snap peas: Harvest when pods are plump and filled out, with seeds clearly visible through the pod. Pods should snap crisply when bent. If pods feel fibrous or strings are prominent, you have waited too long.
Snow peas: Harvest when pods are full-sized but flat, with seeds barely visible as tiny bumps. Hold a pod up to light, and you should see the faint outline of very small seeds, not round peas. Snow peas go from perfect to too mature very quickly.
Check plants daily during peak production. Pea pods develop rapidly, and a day or two can make the difference between ideal and past-prime.
Harvest Technique
Use two hands when harvesting peas. Hold the vine with one hand and pull the pod with the other. Pea vines are delicate, and yanking pods can tear entire sections of vine from the trellis.
Alternatively, use small scissors or snips to cut pods from the vine cleanly.
Keeping Plants Productive
Regular harvesting keeps plants producing. Once peas mature and begin drying on the vine, the plant gets the signal to stop flowering. Pick every pod that reaches harvest stage, even if you cannot eat them all immediately.
If you fall behind and pods over-mature, harvest them anyway and either shell them as fresh shelling peas or leave them to dry completely for seed saving.
Common Problems and Solutions
Powdery Mildew
Symptoms: White, powdery coating on leaves, usually starting on older lower leaves and progressing upward. Common in coastal Santa Cruz's humid conditions.
Prevention: Choose resistant varieties ('Super Sugar Snap,' 'Cascadia,' 'Oregon Sugar Pod II'). Space plants for good air circulation. Water at soil level, not overhead.
Treatment: Remove affected leaves promptly. For severe cases, organic fungicides containing sulfur or potassium bicarbonate can slow spread. UC IPM provides detailed management guidelines.
Aphids
Symptoms: Clusters of small green or gray insects on growing tips and undersides of leaves. Sticky honeydew on leaves. Curled or distorted new growth.
Solutions: Blast with strong water spray. Use insecticidal soap for heavy infestations. Encourage beneficial insects by planting flowering herbs nearby.
Poor Pod Set (Blossom Drop)
Symptoms: Plants flower but pods do not form. Flowers drop off without developing.
Causes: Heat stress (temperatures above 75 degrees F), water stress, excessive nitrogen.
Solutions: Plant earlier in spring to harvest before heat. Ensure consistent watering during flowering. Avoid high-nitrogen fertilizers.
Birds Eating Seeds
Symptoms: Seeds disappear shortly after planting. Disturbed soil where seeds were planted.
Solutions: Cover newly planted beds with row cover or wire mesh until seeds sprout. Remove covering once plants are several inches tall and too established for birds to pull.
Pea Weevil
Symptoms: Small holes in mature pods. Larvae inside dried seeds.
Solutions: Rarely a serious problem in home gardens. Harvest promptly and do not leave pods to over-mature on vines. If saving seeds, freeze them for 48 hours to kill any larvae before storage.
Growing Peas by Microclimate
Coastal Fog Belt
Advantages: Extended growing season, reduced heat stress, excellent conditions for disease-resistant varieties.
Challenges: Powdery mildew pressure, slower drying after rain.
Best approach: Plant resistant varieties. Ensure good air circulation. Focus on spring and fall plantings with potential for extended harvests into June (spring) or January (fall).
San Lorenzo Valley
Advantages: Good growing conditions in sunny spots, cool nights favor peas.
Challenges: Variable microclimates, some frost risk for fall plantings.
Best approach: Choose your sunniest spots for peas. Monitor fall plantings for frost and provide protection if needed.
Under Redwoods
Advantages: Naturally cool conditions reduce heat stress. Extended harvest possible.
Challenges: Reduced light limits production, acidic soil may need amendment.
Best approach: Grow peas in the brightest available spots. Accept lower yields in exchange for extended season. Lime soil if pH is below 6.0.
Inland Valleys and Pajaro Valley
Advantages: Warmer soil speeds germination and early growth.
Challenges: Shorter spring season due to earlier heat. Fall planting window is narrower.
Best approach: Plant as early as possible in spring (January). Time fall plantings carefully, and consider heat-tolerant varieties if available.
Frequently Asked Questions
What is the difference between sugar snap peas and snow peas?
Sugar snap peas have thick, plump pods harvested when seeds are fully developed. Both pod and seeds are eaten for their sweet crunch. Snow peas have flat, thin pods harvested before seeds develop significantly. They are prized for their delicate texture in stir-fries.
Why are my pea pods tough and stringy?
You are harvesting too late. Sugar snaps should be picked when plump but before strings become prominent. Snow peas should be picked when nearly flat, before seeds create visible bumps. Check plants daily and harvest promptly.
Can I grow peas in containers?
Yes, compact varieties like 'Sugar Ann' (sugar snap) and 'Oregon Sugar Pod II' (snow) work well in containers. Use at least 5-gallon containers with good drainage. Provide support even for short varieties.
My peas flowered but the blossoms fell off without making pods. Why?
Blossom drop usually indicates heat stress. Peas stop setting pods when temperatures exceed 75 degrees F consistently. Plant earlier in spring to harvest before heat arrives, or focus on fall planting when temperatures are cooling.
How long do peas keep producing?
In Santa Cruz's mild conditions, healthy pea plants produce for 4 to 6 weeks or longer. Regular harvesting extends production. Once plants stop flowering (due to heat, age, or stress), production ends within 1 to 2 weeks.
Should I let some pods mature for seeds?
If you want to save seeds, let pods dry completely on a few healthy plants at season's end. Mark these plants and stop harvesting from them. See our guide to Saving Bean and Pea Seeds for complete instructions.
Can I eat the pea shoots and tendrils?
Yes, pea shoots (the tender growing tips with a few leaves and tendrils) are a gourmet green. Harvest by pinching off the top 3 to 4 inches of vine. Plants will branch and continue producing, though heavy shoot harvesting reduces pod yield.

Santa Cruz County cool-season schedule
Direct sow seeds 1 inch deep, 2-3 inches apart. Install trellis first. Seeds germinate in cool soil. Roots establish through winter.
Plants grow slowly but steadily. Protect from heavy rain splash. Guide tendrils onto trellis as they grow. Minimal watering needed (rain does the work).
Flowers appear, then pods follow quickly. Pick every 1-2 days for continuous production. The more you pick, the more they produce.
Heat ends production. Remove vines, cut at soil level (leave roots to decompose and release nitrogen). Plant warm-season crops in the same spot.
