Peas in Zone 10B — Florida

Peas bring the satisfaction of sweet, crispy pods and tender seeds to your Florida winter garden when many other vegetables struggle in our cooler months. Here in Zone 10B, you can grow both snap peas and shelling peas during our prime cool season, enjoying homegrown sweetness that store-bought versions can't match. They're perfect for our reversed growing calendar since they actually prefer the mild temperatures we get from late fall through early spring.

While our extreme humidity and sandy soils can challenge many crops, peas are surprisingly manageable when you plant them during our natural cool window. With our 360-day growing season, you have plenty of flexibility to time your plantings right and even succession plant for extended harvests throughout winter and early spring.

Transplanting pea seedlings works in Florida, though it's not the preferred method since peas develop better root systems when direct-sown. If you choose to transplant, plan to move your seedlings outdoors from early December through early January when our temperatures stay consistently mild.

Start hardening off your pea transplants about a week before planting by gradually exposing them to outdoor conditions. Begin with a few hours of morning sun and work up to full days outside. Space transplants 2-4 inches apart in rows, giving them room to climb their support structure.

Watch for those occasional warm spells we get in December and January - if temperatures spike into the 80s for several days, provide some afternoon shade for newly transplanted peas until they establish. Our winter humidity actually helps transplant shock, but avoid transplanting during heavy rain periods when soil stays soggy.

Direct sowing is the recommended method for peas in Florida since they develop stronger root systems and handle our sandy soil better this way. Sow your seeds from late November through mid-October, timing plantings to avoid the hottest part of our year while taking advantage of our mild winter temperatures.

Prepare your soil by working in compost to help with moisture retention in our sandy conditions. Peas prefer soil temperatures between 45-65°F, which we typically get during our cool season. Plant seeds 2-4 inches apart and about 1-2 inches deep, making sure soil stays consistently moist but not waterlogged.

Since peas are nitrogen-fixers, they actually prefer soil that isn't overly rich in nitrogen. Focus on good drainage and organic matter rather than heavy fertilization. In our climate, direct-sown peas establish quickly and are more resilient to the humidity fluctuations we get during winter months.

Peas need consistent moisture but hate soggy conditions, which can be tricky to balance during Florida's wet winter months. They require about 1 inch of water per week, but adjust based on our seasonal rainfall patterns. During dry spells, water deeply but less frequently to encourage strong root development in our sandy soil.

Use the finger test regularly - stick your finger 2 inches into the soil near your plants. If it feels dry at that depth, it's time to water. With our high humidity, avoid overhead watering which can promote fungal diseases. Instead, water at the base of plants or use soaker hoses to keep foliage dry.

Watch for signs of stress during flowering and pod development, when consistent moisture is most critical. Underwatered peas show wilted leaves and poor pod set, while overwatered plants develop yellowing leaves and weak growth. Our frequent winter rains often provide adequate moisture, but be ready to supplement during dry periods.

Apply a 2-3 inch layer of organic mulch around plants to help regulate soil moisture and prevent the rapid drying that can happen in our sandy soil. Pine straw or shredded leaves work well and won't compete with the peas' shallow root system.

Even bush pea varieties benefit from some support in Florida's sometimes gusty winter weather. Install a simple trellis, fence, or string support system at planting time - waiting until plants are established can damage their shallow roots. For climbing varieties, provide 4-6 foot tall supports; bush types need only 2-3 feet.

A basic A-frame trellis made from bamboo poles or a section of cattle panel works perfectly for pea vines. You can also use the "pea brush" method by inserting branchy twigs along the row for plants to climb. Whatever system you choose, make sure it's sturdy enough to handle both the weight of mature plants and occasional strong winds.

Train young pea shoots to their supports by gently wrapping tendrils around the structure. Once they get started, peas climb naturally using their tendrils. In our humid climate, good support also improves air circulation around plants, helping prevent fungal issues that can develop in still air.

Your first pea harvest typically arrives in late to early January, about 60 days after sowing. For snap peas, harvest when pods are plump but still bright green and crisp. Shell peas are ready when you can see round seeds clearly outlined in the pod, but before pods start turning yellow or becoming tough.

Check your plants daily once harvest begins - peas mature quickly in our mild winter temperatures. Use both hands when picking: hold the vine with one hand and gently pull the pod with the other to avoid damaging the plant. Harvest in the morning when pods are crisp and full of moisture.

Regular picking encourages continued production, so don't let pods get overripe on the vine. If you miss some and they become tough or yellow, remove them to keep plants producing. Peak harvest usually lasts 2-3 weeks, but succession plantings can extend your season.

As we approach late December when our first frost risk arrives, harvest any remaining pods even if they're not fully mature. Green pods can be used in stir-fries or soups, though they won't be as sweet as properly ripened ones.

Powdery Mildew This fungal disease appears as a white or grayish powdery coating on leaves, stems, and sometimes pods. Affected leaves curl, turn yellow, and eventually die, reducing plant vigor and harvest. In Florida's fluctuating humidity, powdery mildew thrives during periods when days are warm but nights cool down significantly. Unlike many fungi, it actually prefers dry leaf surfaces, which can catch gardeners off guard. Improve air circulation by proper spacing and installing supports early. Remove affected leaves immediately and dispose of them away from the garden. Neem oil or potassium bicarbonate sprays help control spread, and surprisingly, a milk spray (1 part milk to 9 parts water) can be quite effective.

Pea Aphids These small, soft-bodied insects cluster on new growth, stems, and under leaves, causing stunted growth and yellowing. They can multiply rapidly in our mild winter temperatures, and their honeydew secretions can lead to sooty mold. Check plants regularly, especially new growth tips where aphids prefer to feed. Strong water sprays can dislodge light infestations, while insecticidal soap or neem oil controls heavier populations. Encourage beneficial insects like ladybugs and lacewings by planting diverse flowers nearby.

Root Rot Waterlogged conditions in our heavy winter rains can lead to root rot, causing plants to wilt, yellow, and eventually die despite adequate soil moisture. Our sandy soil usually drains well, but low areas or compacted soil can create problems. Ensure good drainage by raising beds or adding compost to improve soil structure. Avoid overwatering during rainy periods and space plants adequately for air circulation.

Florida Specific Challenges Our high humidity and frequent winter rains create perfect conditions for fungal diseases, while our sandy soil can lead to inconsistent moisture levels. The combination of warm days and cooler nights during our growing season can stress pea plants, making them more susceptible to problems. Focus on proper spacing, good air circulation, and consistent but not excessive watering to grow healthy peas in Florida's unique climate.

Carrots make excellent companions for peas since their deep taproots don't compete with peas' shallow root system, and carrots actually help break up our sandy soil for better water infiltration. Radishes and turnips work similarly, growing quickly in the cool season alongside peas while their roots improve soil structure. Corn provides natural support for climbing peas if planted early enough, though timing this combination requires careful planning in our reversed growing season.

Avoid planting onions and garlic near peas, as these alliums can inhibit pea growth and nitrogen fixation. In Florida's humid conditions, this combination also tends to create areas with poor air circulation, increasing fungal disease pressure. Stick with root vegetables and leafy greens that share peas' preference for cool weather and consistent moisture.
