You don’t need to soak pea seeds before sowing, but it’s an option! I don’t because it’s one less job. Seeds swell quickly when in moist compost and soil.

• Seeds germinate in six to ten days.

Sowing time

The standout time to sow is from late winter to early spring under cover, and early spring outside. This allows your plants to capture their natural, healthy time for growing a lot before flowering. Later sowing risks mildew and perhaps pea moths too, resulting in smaller harvests.

I find best results from sowing under cover, in warm weather as much as cool.

Sowing method

DIRECT

If you sow outside, draw a drill 5 cm/2 in deep from ridge to furrow and drop pea seeds in it. If soil is dry, water the bottom of the drill before sowing. Space according to variety and desired harvest.

Problems are more likely with direct sowing, compared to modules under cover.

• Mice eating seeds is a big issue.
• Birds may pull out the first tiny leaves, in order to eat the sprouted seeds.
• In dry weather, moisture is more difficult to maintain during germination, compared to when module sowing.

MODULES

Modules for peas can be any size, from 3–5cm/1.2–2 in diameter and depth. The aim is not to set out large plants, but to have them securely growing and underway. You can sow, transplant and grow pea plants in clumps.

• For pea shoots, sow any number from three to five seeds in a cell.
• For pea pods, sow two to three seeds. Compared to peas for shoots, the plants grow larger and for longer, needing more space.

When filling modules, firm the compost less than usual and pop pea seeds in the middle of each cell. For each clump of seeds, there is no need to space them out. Push down on seeds and compost to make the compost firm, with pea seeds below surface level. Then fill with more compost, even heap it up a little to gain volume.

Now water a few times, to ensure 100% moisture level in all modules.

Transplant size and time

Once peas are two to three weeks old, still quite small, they are better in the ground. You should not need to pot them on.

The weather may still be cold, even frosty. Pea plants resist frost, but fleece covers mitigate the cold and give shelter from wind. In addition, they protect pea seedlings from birds and rabbits, although not rodents sadly.

Hardening off

This is the name used for adapting plants to different conditions. How necessary is it for pea plants raised under cover?

This partly depends on what ‘under cover’ means.

• If your peas have been under lights in a warm house and are going into a cold garden, I would take out the plant trays during the daytime, for two days before planting.
• From a cold greenhouse on the other hand, which is closer to natural conditions and light, I find that no hardening off is necessary, as long as transplants are covered straightaway with fleece.

Transplant method

To check the supposed need for hardening off, I took module-raised pea plants off the top of my hotbed, where their rootballs were at least 25 °C/77 °F, and put them straight into soil at  7 °C/45 °F. This was outside in March, early spring. It was a big temperature difference, but I laid fleece on top and they grew fine.

Set transplants into reasonably deep holes, not filled in, leaving the pea stems a little below soil level.

This gives added wind protection, even under fleece, and if it snows, plants suffer little damage from any weight of snow because they protrude less above ground level – see the photos above.

Spacing

You have options, according to the type of pea and desired harvest.

• 22 cm/9 in equidistant for shoots is straightforward, similar to almost all plants for salad. They need no support.

For peas you support, double rows use space more fully – a row on either side of the line of supports. For a bed of 1.2 m/4 ft width, the double row along it works well for ease of picking. Even though it looks wide at first, plant roots fill that soil space and leaves spread out above. Space transplants at 15 cm/6 in along each row.

• Or run the double row and its supports across a bed of any width, as in the photos below. Allow 37–45 cm/15–18 in of space to the next row of vegetables either side

Interplant peas for shoots

This is possible, mainly between other salad plants since they are picked small as well. No plant overpowers another at first, or until a little later!

My experience of this is mostly under cover, through winter. You can translate it to outdoors in spring.

Support

The videos should give the most help on this.

There is no one solution, everyone has a preferred option and that is excellent.

• A YouTube viewer said he loved my method of string supports, until pigeons worked out how to sit on them and eat the pea leaves.
• Pea tendrils cling strongly to any twigs or netting, so branches with twigs are good. However, with netting especially, it needs a while to disentangle all the tendrils after final harvest.
• Check the description of any variety you grow, to know how high your supports should be.

‍

Tall peas need more water than dwarf peas. Their growth is like a thick hedge in your garden, for a month or so, with masses of leaves all transpiring moisture.

• When you first see flowers on plants for pods, it’s important to water them if the weather is dry.
• From this stage, water two or three times a week, a good amount.
• Even in damp weather, pea plants’ speed of growth through early summer can make watering worthwhile.
• Peas for shoots need moisture to keep producing. If plants are stressed by dry roots, they grow fewer shoots and more flowers. Their picking season may be curtailed.

Extra mulch to retain moisture?

This is worthwhile in dry climates, less so in moist ones. Peas are not in the ground for more than half a season.

If you plan to follow peas with slug-sensitive plants like chard and salads, any undecomposed mulch can reduce growth of subsequent plantings.

I have created two sections here, for shoots and pods.

SHOOTS

How to judge readiness

First shoots may be ready in cool spring weather, when plants are less than 30 cm/12 in tall.

• The question is, what is a shoot?

Each person picks them differently, at any length, as long as the stem is tender. For tall varieties, the shoots are longer and bulkier.

Sometimes shoots have tendrils and these are edible, but you may not like them! Just occasionally, shoots will have flowers. This is normally a bad sign for shoots because the stems are now thinner and more fibrous, and flower stalks are also chewy. If there are many flowers, final harvest is close, before removing plants. Unless you leave them for a (small) harvest of pods.

How to pick

Pinch the tender stems between your finger and thumb, or use a knife if you wish. It’s a quick job and the harvest is not heavy.

After your first pick of the main leader, there may be new shoots within a few days if temperatures are high, say 21 °C/70 °F, or within a week if it’s cool, say 12 °C/54° F by day. New shoots appear from the plant base and at all levels, so look closely, including under leaves, for new shoots.

When to pick and how often

By early summer, harvests are frequent and more substantial. The main period of harvest quantity is June or early summer, and then it tails off rapidly by solstice, as plants switch from growing to flowering.

Early morning is a lovely time to pick shoots, at a time of year when birds are singing and there is the gorgeous dew of spring. Shoots gathered in the cool of morning will store for longer, in a plastic bag to retain moisture.

PODS

How to judge readiness

For mangetout, pods need to be thin, with just a slight swelling along the line of baby peas inside. If allowed to grow fat, the pods are not mangetout any more. They become stringy and peas need to be shelled out, though it is still an excellent harvest.

For snap peas, the sweetest result is when pods are reasonably fat. You can also pick them half empty, for tasty pods with less sweetness. The sweetness comes from the swollen peas, before they turn firm and starchy.

For peas to shell, pods need to look reasonably round and feel firm. However don’t wait too long, otherwise peas become more dry, dense and less sweet.

• Or allow this extra maturity, when leaves change from green to yellow, if you want a harvest of dry peas to store.

How to pick

Search among your plants for pods that are ready. Generally, the first ones swell near ground level, but not exclusively. Pods may be hidden behind leaves, so look carefully to find all the ready ones.

To detach pods from plant stems, pull sharply and firmly, with the other hand holding plants to prevent stem breakage. Each pod, or pair of pods – they often hang in two’s – are best with their stalks attached after picking, so that pods are undamaged and peas stay fresher.

When to pick and how often

First pickings feel rare and precious. Then, within ten days, you can pick every two to three days and the amount increases. Pick frequently in warm weather – the table below shows how harvests get heavier each week, from there being more pods, and also thanks to higher pod weight as peas swell.

The table shows harvests from Podding Pea Starlight – module-sown on 17th February (seven plants across the 1.5 m/5 ft bed), transplanted on 13th March and staked in mid-April.

DateWeight (kg)14th June0.2318th June0.521st June0.6825th June1.092nd July1.549th July1.9TOTAL5.94

Another yield figure is from Oregon Sugar Pod, in a bed of 1.5 x 7m/5 x 23ft – see the photo gallery below.

• The first pick, mid-June, gave 2 kg/4.4 lb of mangetout pods, then more picks every two to three days.
• By the end of June, there were no thin pods and we were picking pods for shelling.
• The final pick on 5th July gave 9.1 kg/20.1 lb of delicious shelling peas, and pods for making wine.

Storing

Pea shoots are full of moisture and peas in pods are full of sugars. Neither store well and are best enjoyed within two days at the most.

Saving seed

Peas are perhaps the easiest vegetable to save seed from, for two reasons:

1. They do not cross-pollinate between varieties. You need only one plant of any one variety to save seed that will grow true. Or you could grow two varieties near to each other, and seed from both will grow true to type, with no crossing.
2. Seed saving is quick and easy, because the harvest of pea seeds happens soon after the harvest of green peas to eat. Allow three to four weeks after a final pick of pods for green peas, depending on the weather.

After picking the dry, or almost dry pods, shell their peas and leaves somewhere dry and warm, to ensure full dryness before packaging in envelopes or Tupperware.

Pests

Pea moths (Cydia nigricana)

They fly from early summer, causing most damage after the summer solstice.

I know of no remedy except to sow early, for harvests to finish before moths are numerous.

Often you don’t know that caterpillars are there, until you find eaten peas when shelling.

The moths lay eggs on stems, then young caterpillars enter pods from above and spend up to three weeks inside, eating and excreting.

Weevils of pea and bean (Sitona lineatus)

Visible damage can be seen in serrations around the edges of young leaves in late spring to early summer, while invisible damage is through roots being eaten by the larvae, from mid-spring. Usually the harm is mainly cosmetic, especially in fertile and moist soil.

• Transplanting in early spring sees plants establish before the pests do, meaning that plants then have tougher leaves by the time there are adults hatching. Some leaves will be notched, but growth should continue fine in healthy and well-fed soil.
• This is a similar principle to avoiding blackfly damage on broad beans, whose leaves (not pods!) are tougher from early sowings.

Disease

Pea powdery mildew (Erisiphe pisi)

The lower leaves of plants begin to show signs of mildew in early summer, especially in dry weather. Therefore one remedy is to keep plants well-watered.

• However, powdery mildew on pea leaves is totally normal from midsummer and is best reduced by sowing early in spring, say March rather than April. This means you harvest before mildew is too developed.

In contrast, the sowings of late spring will be ripening in midsummer, often with some leaf mildew, and the result is peas not being sweet. Mildew prevents leaves from photosynthesising to produce sugars.

• You can sow mildew-resistant Terrain in spring if worried about mildew, as well as sowing it in early summer for harvests in autumn. They are less heavy than in summer, from the same number of plants.
