Valentines Day - Time for Pea Planting!

Garden tips for Peas: In our region (Zone 8b - Last frost-date zone map - USA), its ideal to plant peas around Valentine's Day. This gives them the best head start for blooming in time for the longest possible harvest season. The problem is that, here in Alpine/Monroe, Oregon, the soil is often very wet and cold this time of year and, even if you get a good start sowing seeds directly in the soil, the March and April rains can significantly retard their growth, the seedlings can rot off at soil-level, or slugs can decimate your starts.

If you have raised beds, direct sowing shouldn't be an issue but if, like us, you don't have that luxury, what follows is a method we've used successfully for several years  to deal with these challenges. 

By starting seeds in pots and later transplanting them it will increase your chances of an early, abundant edible-pod pea harvest. 

For this method you will need a greenhouse (or indoor seed-germination set-up), and live in a similar climate as the Sharing Gardens (we're in zone 8b, according to the USDA zone map). You can start your seeds in pots much earlier than you would be able to direct sow them outside. Depending on when you start the seeds, they can be transplanted into a greenhouse for earliest pea-production, or later, to beds outside.
 
Peas, started in pots.
For plants that will be grown out in our greenhouse,
we start our seeds as early as the first week of January. These are then transplanted to greenhouse raised beds by mid-February. Seeds started in pots in mid-February can be transplanted to outside beds in March. 
 
By starting our first batch of seeds at the new year, we can be eating peas by late March and on into April - at which point the peas we plant outside the greenhouse will begin producing and carry us through May or June!

You'll need:
  • Seeds: Our favorite varieties are: Sugar Snaps - delicious pods/shorter trellis - 6' or Melting Sugar - need a tall trellis - 8' - very prolific but not as sweet.
  • Soil
  • 4" pots (4-6" deep) - the deeper pots give more time before plants become root-bound. You'll need one pot per two seeds. Plants will be transplanted at a spacing of 6"-8".
Fill pots to within a half-inch of the top. Water the soil to help it settle.

Poke two seeds, in opposite corners, about the depth of one knuckle (3/4" or so). That's two seeds per pot. This gives each plant enough soil to germinate and grow to several inches in height before you transplant. Cover the seeds with soil (about the depth of two seeds-deep) so they're not exposed to sun. Water them gently. Do not over-water. Seedlings can rot if soil is too damp.

Plant two seeds in opposite corners.Note: Since having written this article, we have now shifted to planting two seeds per pot but do not have photos to reflect this.
Keep the potted seeds protected from marauding slugs by putting them up on a table, or putting a milk-carton collar around them. (Link to post on Re-Purposing Things - including milk-cartons as collars). 
 
If you're planting in January, you'll need a greenhouse, or indoor germination set-up to protect them and keep soil in pots warm enough for germination. If you wait until mid-February, pots can be outside in a sunny place, protected from north winds. Temporarily bring them inside if faced with a severe freeze.
Pea seedlings in pots. Pea leaves and tendrils are edible and delicious in salads.

When they are at least 6", and no longer than 12", you can put them in your garden, or greenhouse beds. Best to wait until their root-systems are quite dense in the pots -- almost "root-bound". They will be easier to transplant without damaging the plants. On the other-hand, if you wait until the stems are too long, you risk breaking stems during transplanting so it's a matter of finding the right balance.
 
These peas are ready to be transplanted! In fact they're almost too well developed! Tendrils from neighboring plants are starting to entwine. Pea plants are very fragile and you must be careful not to break the stems.
Transplanting: Plant each 4" pot (with its two seedlings) about 8"- 10" apart with thin bamboo stakes or other climbing trellis in between each clump of starts. (Note: peas need a trellis with stakes or caging that is less than 1/2" (1 cm) in diameter. They climb using tendrils (instead of wrapping around the trellis - like beans) and won't be able to grab and climb if your trellis/caging uprights are too thick.)  
 
Pea-plants are not typically transplanted but sowed directly in place. They are very susceptible to shock so be gentle with the roots and stems. Best to have your trellis in place before you transplant so you don't injure roots driving in the stakes.  
 
If slugs are a big issue in your area, planting them in milk-carton collars can make a big difference. We also typically sprinkle about a teaspoon of iron-phosphate ("Sluggo") around each bunch of plants. This is an organically-approved way of dealing with slug/snail infestations in your garden. (LINK to article about iron phosphate).

The plants might go through a little stress from transplanting but once they acclimatize to their new environment they'll be well along the way to yielding a bounteous and long-term harvest!

Good idea to have trellis in place before you transplant peas (so you're less likely to damage roots). The plants will go through a little stress from transplanting but once they acclimatize to their new environment they'll be well along the way to yielding a bounteous and long-term harvest!

Pea-vines headed for the compost pile. Peas, being legumes are able to add nitrogen to your soil through a symbiotic relationship with organisms that grow on their roots. This will help improve your soil, particularly if you leave the roots in the ground when you cut down the "greens" to add to your compost pile.
