If you’re planning your Louisiana garden, knowing when to plant purple hull peas in Louisiana is the first step to a great harvest. Getting your timing right with the warm Southern climate makes all the difference for a bumper crop of these Southern favorites.
This guide gives you the optimal spring planting schedule, tailored to our unique growing zones. We’ll cover everything from soil temperature to specific dates so you can plant with confidence.
When to Plant Purple Hull Peas in Louisiana
For a successful spring crop, the optimal planting window across most of Louisiana is from mid-March through early May. The exact best time for you depends heavily on your specific location and the current weather conditions each year.
Purple hull peas are a warm-season legume. They thrive in heat and will not tolerate frost. Planting to early in cool, wet soil is a common mistake that leads to poor germination or rotted seeds.
Understanding Louisiana’s Growing Zones
Louisiana spans USDA hardiness zones 8a to 10a. This range affects your last spring frost date, which is the key date to work from.
- North Louisiana (Zones 8a-8b): Last frost is typically around late March to early April. Aim to plant from early April to early May.
- Central Louisiana (Zones 9a-9b): Last frost usually occurs by mid-March. You can safely plant from late March through late April.
- South Louisiana (Zones 9b-10a): The frost risk ends earliest here, often by late February or early March. Planting can begin in mid-March and extend into May.
The #1 Rule: Soil Temperature is Key
More important than the calendar date is the temperature of your soil. Use a soil thermometer to check at a 2-inch depth.
- Optimal Soil Temp: 65°F to 70°F for best germination.
- Minimum Soil Temp: 60°F. Planting below this risks slow growth and seed rot.
- Wait until soil has warmed and dried out from spring rains. If its sticky and clumpy, its to wet to plant.
Spring Planting Schedule by Month
Here’s a month-by-month breakdown for spring planting across the state.
March
Proceed with caution this month. Focus on preparation.
- South LA: Late March is often safe. Check soil temp.
- Central & North LA: Primarily a prep month. Till garden beds, add compost, and let the sun warm the soil. You can start seeds indoors in pots if you want a head start.
April
This is the prime planting month for most of the state.
- North LA: Plant early to mid-April.
- Central LA: Plant throughout April.
- South LA: Continue planting; its a great time for successions plantings.
May
The final call for a full spring/summer harvest.
- Plant by early May in North Louisiana.
- In Central and South Louisiana, you can plant through mid-May for a later summer crop.
- Later May plantings may be more susceptible to pest pressure as summer heats up.
How to Plant Purple Hull Peas for Success
Follow these steps for a strong start.
- Choose a Sunny Spot: Select a site that gets at least 6-8 hours of full sun daily.
- Prepare the Soil: They prefer well-drained soil. Work in 2-3 inches of compost or aged manure. Purple hull peas fix their own nitrogen, so avoid high-nitrogen fertilizers which promote leaves over pods.
- Planting Seeds: Sow seeds 1 inch deep and 4-6 inches apart in rows spaced 24-36 inches apart. You can also plant in wide rows or blocks.
- Water Gently: Water thoroughly after planting. Keep soil moist but not soggy until seeds sprout, which takes 7-14 days.
- Consider Succession Planting: For a continuous harvest, plant a new batch of seeds every two to three weeks until early summer.
Caring for Your Growing Purple Hull Peas
Once they’re up, peas are relatively low-maintenance.
- Watering: Water deeply once a week if rainfall is lacking. Avoid overhead watering to prevent foliar diseases.
- Weeding: Weed carefully when plants are young. A light mulch can help suppress weeds and retain moisture.
- Support (Optional): While many varieties are bush-types, some can benefit from a small tomato cage or light trellis to keep pods off the ground, especially in rainy seasons.
When to Harvest and What to Expect
Most purple hull pea varieties are ready for harvest 60 to 70 days after planting.
The pods are ready when they are well-filled and have turned a deep purple or burgundy color. The hulls may also show a slight silvering. Shell a few test pods; the peas should be plump and tender. For a “snap” pea, harvest them a bit earlier when the pods are more green.
Regular picking encourages the plant to produce more pods. If you have a big patch, you can even pull up whole plants when most pods are ripe and shell them all at once.
Common Problems and Simple Solutions
Watch out for a few typical garden issues.
- Poor Germination: Usually caused by planting in soil that’s to cold or to wet. Wait for warmer, drier conditions.
- Leaf-Footed Bugs & Stink Bugs: These are the main pests. Hand-pick them off or use an organic insecticidal soap. Planting early can sometimes help you miss the worst of their population boom.
- Root Rot: Caused by overly wet soil. Ensure good drainage and avoid overwatering.
FAQ: Your Purple Hull Pea Questions Answered
Can I plant purple hull peas in the fall in Louisiana?
Yes! Louisiana’s long growing season allows for a fall crop. Plant about 70-80 days before your first expected fall frost, typically from late July to mid-August in North LA and into September in South LA.
What are the best purple hull pea varieties for Louisiana?
Great choices include ‘Pinkeye Purple Hull’, ‘Texas Pinkeye’, ‘Mississippi Purple’, and ‘Early Scarlet’. These are all well-suited to our heat and humidity.
How late is to late to plant purple hull peas in spring?
Planting after late May in most areas risks the pods maturing during the intense peak summer heat and drought, which can stress plants and reduce yield. Its better to wait for a fall planting if you miss the spring window.
Do purple hull peas need a lot of fertilizer?
No. As legumes, they pull nitrogen from the air. Too much fertilizer, especially nitrogen, will give you lots of leaves and few pods. Compost at planting is usually sufficient.
Can I save seeds from my purple hull peas for next year?
Absolutely. Let some perfect pods dry completely on the vine until they are brown and rattle. Shell them and store the dry peas in a cool, dark place. They’ll be ready to plant next spring.
By following this schedule and tips, you’ll be able to enjoy a homegrown harvest of purple hull peas that’s perfect for your table. Remember, the key is warm soil, good timing, and a little bit of patience while nature does its work.
