Sugar Snap Peas

Have you considered growing peas? Looking for something to feed your sweet tooth, straight from the garden? Look no further than the Sugar Snap pea. There’s a reason they’re called “garden candy.”

The Sugar Snap is actually a relative newcomer to the garden (first introduced in 1979), but it is now established as one of the great treats of spring. When my Sugar Snaps start to ripen they become the center of the garden and remain so until all the pods are gone.

The Sugar Snap differs from traditional garden peas (like Green Arrow) in that the whole pod is edible, and differs from the edible podded snow peas (like Mammoth Melting) in that the pod is fat, sweet and delicious.

As the whole pod is edible they produce a significantly bigger harvest and don’t need shelling. The original Sugar Snap variety was so successful it eventually spawned a whole range of snap peas: bush varieties, disease resistant types and some without strings. There are now even yellow, purple and pink tinted types.

The Sugar Snap was hailed as a revolutionary new kind of pea when it appeared, but it wasn’t actually as new as it seemed at the time. It turns out that the Amish have been growing snap peas for a long time and they are so similar that a casual observer probably wouldn’t be able to tell the difference.

Should I grow peas?
Peas (along with beans) have a special place in the vegetable garden because they are host to nitrogen fixing bacteria and so can add fertility to the soil as they grow. This won’t happen unless the right type of bacteria is present in the soil though, so if you haven’t grown peas within the last five years you should inoculate the seed with a suitable strain of inoculant.

The real flavor of Snap peas comes through best when they are eaten raw and this is how almost all of ours get eaten. My children will eat them straight from the vine all day long and few pods actually make it as far as the kitchen (their friends have been known to strip a planting of all pods of any significant size). They are also good when very lightly steamed, but don’t cook them for more than a couple of minutes, or they may turn to mush.

Tips on growing great peas
Air Temperature: Peas thrive in cool weather and don’t like heat, with 60-75˚ F being optimal. They are fully hardy and the first planting can be sown directly into the garden in early spring, a month before the last frost date.

Soil Temperature: The soil doesn’t even have to be very warm, as they will germinate (if rather slowly) at temperatures as low as 40˚ F.

Succession Planting: It is a good idea to make several succession plantings about 3 weeks apart, to ensure an abundant supply of pods until the weather gets too warm.

Weeding: The established plants don’t require much care. Weeds can be a problem for the young seedlings, but they soon outgrow and overshadow any weeds.

Watering: They do need regular moisture, but in early spring there is usually plenty in the soil and you rarely need to water.

Getting set up
The original Sugar Snap is a pole variety and must have a tall support structure for good growth (hog wire fence works well). If it isn’t tall enough they will eventually run out of climbing room and flop over (when my dad first grew them in England they went right over the top of his 6 foot high wall and started supplying his neighbor with pods).

It is a good idea to set up your supports before you plant, as it’s easy to damage the fragile seedlings. If you don’t want to deal with such a tall plant there are now bush varieties, such as Sugar Ann.

It is easier to provide support for the plants when they are growing in rows, so they are commonly planted in double offset rows with 3” between the plants and 6” between the rows. If you need more than one double row, then leave 24” between the pairs of rows.

You can also wrap hog wire fence into a cylinder and plant in a circle around it (this looks quite ornamental when fully covered, though not for long).

Established plants grow vigorously and quickly produce a wall of foliage 6 to 8 feet high, which makes an attractive (though temporary) screen.

Pests to watch out for
The biggest obstacle to growing Snap Peas is getting them established. It’s not that they are hard to germinate (this is easy) but rather that birds like to eat the succulent green parts and often pull the emerging seedlings out of the ground. The best way to prevent this is to cover the whole bed with netting.

Mice can sometimes be a problem too, as they sometimes dig and eat the seed before it has even germinated. If they are a problem you might have to start your plants indoors, though they dislike transplanting, so must be grown in individual cell packs (and not kept indoors for too long).

Ready to harvest!
The pods mature quickly after pollination and you need to check and harvest the plants regularly (every day or so). Harvest the pods when they are fat and round and sweet to taste. Don’t harvest too early or they won’t be as good as they can be.

It is important to pick all of the pods as they size up, if you leave some on the vine the seed will mature and production may decline (if this happens save the seed for planting next year). In cool weather, a well managed planting may yield for 6 weeks or more, though if the weather turns hot it may be as short as 2 weeks.

Peas for St. Patrick’s Day

Image: Peasl Photo source: Jessica Ruscello, UnsplashIn Ireland, St. Patrick’s Day is the traditional day to plant peas in a spring garden. In the United States the timing can vary somewhat from zone to zone, but March 17th still works well as a guide for starting peas for most areas. And what a perfect way to bring your garden a bit of the “luck of the Irish” by planting something green!

Why you should grow peas.

Did you know peas have been cultivated by humans for anywhere from 8,000 to 12,000 years? Peas are an easy, rewarding crop for spring, and are a great way to fix nitrogen in the soil for your summer plants. As an early spring crop they can be out of the ground by June, leaving time for a warm weather crop to succeed them.

Selecting a variety.

Dried Shelling Peas are typically used for soups or stews, and fresh shelled immature peas are good lightly steamed or boiled. Their pod is too fibrous to be edible, and the peas themselves must be removed from the shells, hence their name. Bush Shelling peas grow in a compact bush form, while the more common Vine Shelling peas, which grow on vines that require staking or trellising but which are generally more productive than bush varieties.

Snap Peas are a more recently developed edible-podded pea, this one originated in America. The pod is thicker and more succulent than that of the Snow Pea, and less fibrous than standard Shelling Peas. These are now one of the most popular types of pea, because there is no work in shelling and very little waste.

Snow Peas have thin crisp pods that are nearly translucent and bright green, with tiny seeds. The whole pod is edible and quite sweet when picked at the right time. The name may come from the whitish tint reflected from the pods, or because of their tendency to grow at the end of winter, just before the last spring freeze. As their name suggests, they can be covered with snow during these times, but still keep growing.

When to plant.

In moderate climates, you can sow directly into your garden bed, while in colder climates you may need to start them indoors. Fortunately, peas do well in containers, so you may not even need to transplant them!

In warmer climates, you may have already started your peas back in January or February, but you can still continue to sow new seeds for a second harvest before the warm days of summer.

Getting started.

The best soil for peas is a loose well-drained loam. Peas don’t need a lot of nitrogen, as they can obtain their own. In fact, if nitrogen is too easily available they won’t bother to fix any. Peas do need phosphorus (colloidal phosphate) and potassium (wood ashes), as well as calcium and magnesium (use dolomitic limestone).

If the soil is compacted double digging is beneficial. If it is poorly drained, use raised beds, especially for early plantings, as they don’t like wet soil. In very poor soils it may pay to plant your peas in trenches, filled with a mixture of soil and compost.

If you’re growing a vining variety, you will need to supply a trellis or poles for the plants to grow along.

Spring Vegetables

It’s tempting to start planting all those great seeds you bought over the winter, but it’s best to take a moment and consider what weather conditions each plant needs to germinate and thrive. Each plant has an appropriate time to be planted, and it’s important to be aware of which plants can go out at what time.

The vegetables that grow well in spring all originated in temperate climates and prefer cool (50-75˚ F) growing conditions. When you first plant your spring crops, the soil and air are cool and days are fairly short, so crops germinate and grow slowly. As spring progresses the days lengthen and the weather gradually warms, until by the time most crops are ready to harvest it may be warm most of the time. Fall has cool weather too, but there the reverse is true, conditions are warm for seed germination and growth (and pest activity), while maturation takes place in cooler weather.

When to plant

Fortunately cool weather crops aren’t perturbed by minor cold snaps, so planting them early isn’t a big problem. If it is cold they will just sit and wait until the weather warms up enough for growth.

The hardiest crops can be planted as soon as the ground is suitable for making beds in spring, which may be 4 to 8 weeks before the last frost date. These plants include: leek, onion, parsley, pea, spinach, and shallot.

The slightly less hardy crops can be sown 2 to 4 weeks before the last frost date. These include: lettuce, cilantro, mustard, and radish.

The rest of the spring crops are sown a couple of weeks before last frost date. These include: beet, carrot, broccoli, cabbage, chard, kale, and potato.
