Snow Peas in Zone 10A — Florida

Snow Peas are a treat to grow in Florida, offering sweet, edible pods that you can enjoy fresh, stir-fried, or added to salads. Their delicate flavor and satisfying crunch make them a worthwhile addition to your fall and winter garden, and harvesting your own is so rewarding!

While our Florida gardening calendar is different, with summer being the slow season, Snow Peas thrive during our cooler months. With a little attention to timing and variety selection, you can enjoy a bountiful harvest of these cool-season favorites. Our 355-day growing season gives you plenty of time to get them in the ground.

You can transplant Snow Peas outdoors in mid-December through early January. This gives the plants a good start before any late cold snaps.

Before transplanting, harden off your seedlings by gradually exposing them to outdoor conditions for about a week. Place them in a sheltered spot initially, increasing the amount of direct sunlight and wind exposure each day. Space them 3-4 inches apart in well-draining soil.

Keep an eye on the weather forecast, as unexpected cold snaps can occur. If a freeze is predicted, cover your transplants with frost cloth to protect them.

Direct sowing is the preferred method for Snow Peas, and it works great here in Florida. Sow seeds late November through late October, giving you a wide window to get them in the ground.

Choose a spot in full sun to partial shade with well-draining soil. Before sowing, amend the soil with compost to improve fertility and drainage. Sow seeds 1 inch deep and 3-4 inches apart. Keep the soil consistently moist until germination, which usually takes about a week.

Just like garden peas, Snow Peas prefer cooler soil temperatures, so sowing during this window is ideal. They are a quick-growing crop, so you'll be enjoying fresh peas before you know it!

Consistent watering is key for healthy Snow Pea plants, especially during flowering. Snow Peas are not drought tolerant and need consistently moist soil.

During our typically dry fall and winter months, aim to provide about 1 inch of water per week. Use the "finger test" to check soil moisture: if the top 2 inches of soil feel dry to the touch, it's time to water. Water at the base of the plants to avoid wetting the foliage, which can encourage fungal diseases in our humid climate.

In Florida, overhead watering can be risky due to our high humidity. Signs of underwatering include wilting leaves and stunted growth. Overwatering can lead to root rot, indicated by yellowing leaves and a mushy stem base. Mulching around your plants with pine straw or wood chips can help retain soil moisture and suppress weeds.

Snow Peas are vining plants and need support to grow properly. A trellis works best, but even a simple string trellis will do the trick, since Snow Peas are lighter than snap peas.

Install the trellis at planting time to avoid disturbing the roots later. As the vines grow, gently train them to climb the support by weaving them through the trellis or tying them loosely with twine. This will keep the pods off the ground, improving air circulation and preventing disease.

You can expect your first harvest of Snow Peas in late to early January, about 55 days after planting. The pods are ready to harvest when they are flat and you can just barely see the pea outlines inside. They should be translucent and crisp.

Harvest regularly by gently snapping the pods off the vine, being careful not to damage the plant. Frequent harvesting encourages continued production.

As our short days approach in late December, keep harvesting to enjoy your peas before the plants start to decline. Even if a light frost nips the plants, you can often still harvest any remaining pods.

Here are some common problems you might encounter with Snow Peas in Florida:

Powdery Mildew

• What it looks like: White or grayish powdery coating on leaves, stems, and sometimes fruit. Leaves curl, yellow, and die. Reduces plant vigor.
• What causes it: Various fungi that thrive in warm days, cool nights, and moderate humidity. Dry leaf surfaces actually favor it (unlike most fungi).
• How to fix/prevent it: Improve air circulation through spacing and pruning. Remove affected leaves. Neem oil or potassium bicarbonate sprays help. Milk spray (1 part milk to 9 parts water) is surprisingly effective. Plant resistant varieties.

Pea Aphids

• What it looks like: Small, soft-bodied insects clustered on stems, leaves, and pods. They can be green, yellow, or pink. Leaves may be curled, distorted, or yellowed.
• What causes it: Aphids are attracted to stressed plants and can multiply rapidly in warm weather.
• How to fix/prevent it: Spray plants with a strong stream of water to dislodge aphids. Introduce beneficial insects like ladybugs and lacewings. Insecticidal soap or neem oil can be used for heavy infestations.

Root Rot

• What it looks like: Yellowing leaves, stunted growth, and wilting. The base of the stem may be mushy and brown. Roots are often dark and decayed.
• What causes it: Overwatering and poorly draining soil create an environment conducive to fungal growth.
• How to fix/prevent it: Improve soil drainage by adding compost or perlite. Avoid overwatering. Ensure good air circulation. Use raised beds if your soil is heavy clay.

Fusarium Wilt

• What it looks like: Wilting on one side of the plant first, then spreading. Yellow leaves starting on one side. Brown streaks in stem when cut open.
• What causes it: Soil-borne fungus (Fusarium oxysporum). Persists in soil for years. Enters through roots. Warm soil temperatures favor it.
• How to fix/prevent it: No cure once infected — remove and destroy the plant. Plant resistant varieties (look for 'F' on seed labels). Rotate crops on a 4-year cycle. Solarize soil in hot zones. Raise soil pH above 6.5.

Florida Specific Challenges: Our hot, humid summers and wet-summer rainfall make Snow Peas particularly susceptible to fungal diseases like powdery mildew and root rot. Selecting disease-resistant varieties and ensuring good air circulation are crucial for success. Nematodes can also be a problem in our sandy soils, so consider using nematode-resistant varieties or amending the soil with organic matter.

Companion planting can help your Snow Peas thrive in Florida. Carrots and radishes make excellent companions because they loosen the soil, improving drainage, which is especially important in our sometimes-compacted soil. Cucumbers provide shade, helping to keep the soil cool during warmer spells. Corn can act as a natural trellis for the Snow Peas to climb. Lettuce, being a low-growing crop, can help suppress weeds and retain moisture.

Avoid planting Snow Peas near onions or garlic, as they can inhibit their growth. These alliums release compounds into the soil that can negatively impact pea development.
