Bed preparation
- Broadfork the bed to loosen the soil, then shape it with a bed prep rake.
- Peas like a fresh layer of compost. If the last crop got compost, add alfalfa meal and pelleted chicken manure instead and tilth into the top 1-2″.
- Irrigate for 10 to 14 days* to germinate weed seed, then flame weed once the cotyledons are up.
- Peas need soil at 60°F to germinate (68°F is best). In cold soil, cover the bed with plastic for a week before seeding.
Seeding
- Set up the Jang: BL12 roller, 11 x 11 sprockets (front x rear), brush down. That drops a seed about every 3″.
- Two rows on a 30″ bed: 15″ apart, 7.5″ in from each edge. Mark them with the bed prep rake so the furrows are about 1″ deep.
- One pass per row. Test the BL12 with your seed lot at the bench first; pea seed varies a lot in size.
- As backup, start a tray of peas in the nursery a week before field seeding to fill any gaps.
Bed layout
Irrigation
- Run two lines of drip and keep the soil moist for the 7-10 days it takes peas to come up. Hand water if the drip doesn’t cover it.
- Once the vines grow, keeping the pods and leaves dry helps prevent disease.
Cultivation & trellising
- Cultivate 14-18 days after planting with a collinear hoe and side-dress with alfalfa meal or blood meal.
- Once the peas are over 10″ tall, mulch with straw to smother later weeds.
- Drive a 7′ T-post between the rows every 10′. Put a 1.25″ PVC tee on each post and run 1/2″ EMT through them as a top rail, then hang trellis netting from it.
- Run tomato twine along the front of the plants as they grow so they don’t flop forward.
Harvest
- Pick every other day once pods are about as thick as your little finger, working from the bottom of the plant up.
- Pinch the pod between two fingers and snap above the cap with your thumb so it doesn’t break.
Washing and packing
- Don’t wash peas. If they get wet, leave the bins open in the cooler for a couple of hours before closing them.
- Store at 35-40°F and sell within 4 days of harvest.
*All timing varies with your climate, soil and season.

Snap peas with the Jang: FAQ
What Jang roller do I use for snap peas?
BL12, with the 11-tooth sprocket in front and the 11-tooth in the rear, brush down. That gives about 3″ between seeds. Test the roller at the bench with your seed lot before you go to the bed.
How much seed do I need?
About ~800 seeds (about 200 g) for a 100′ x 30″ bed at 2 rows. Round up when you order.
How long until harvest?
About 60 days from seeding, with a harvest window of about 28 days. Timing varies with your climate, soil and season.
