Pea 'Sienna' is a superstar. An excellent early variety that produces a very fast crop of multiple, dark green pods per node. A hardy variety that is well adapted to early spring weather, Sienna handles cool soils very well. The plants have a good tolerance to Fusarium 1, 2 and PM.
The vines average 60cm (24in) in height and bear heavily and more all at once than other vining types. The multiple pods provide a high yield potential. Harvest in about 50 days for tendrils and 61 days for shell peas. Dark green quality peas have a uniform colour at harvest.
This variety is recommended if you’re growing peas for freezing, very convenient, they can be harvested and processed all at once. When freezing peas for storage, shell and blanch within 2 to 3 hours for maximum sweetness.
If you have a small garden, maximising space is also great reason to consider this variety. Sienna are ready to pull from the garden a month or so ahead of other varieties, so the space can be utilised for other crops.
Very easy shelling, with excellent sweet flavour. Open the medium sized, blunt pods and enjoy the first, sweet, plump, green peas of the season!
Peas require a sunny, position with well-drained but rich soil with a neutral pH, so if yours is at all acidic, the ground should be limed a few weeks before sowing.
Ideally, the ground would be dug and manured the autumn before sowing, but if you have good garden soil, a thin dressing of good garden compost or well-rotted manure just before sowing is adequate. This will help to improve the soil’s moisture-retaining ability during hot, dry summers.
In well drained soil, peas can be sown outdoors in November, for an early crop.
In spring, wait until the soil is warm to the touch, which will be some time between the middle of March and the middle of May, depending on your soil and where you live. Putting a layer of fleece over the soil in early March will help warm up the soil by as much as a couple of weeks. Make successional sowings every two weeks.
An old gardeners saying that 'rows should be sown in a North to South direction' had me wondering for years – all became clear when I found this explanation - “Since peas are prone to powdery mildew, plant them in rows that run north and south so that each plant has maximum opportunity for the sun to burn off the dew.”
To grow an early crop, try sowing seeds in a length of old guttering. Drill drainage holes at regular intervals along the base. Fill to the top with seed compost and space the seeds about 7.5cm (3in) apart.
Place the guttering in the greenhouse or cold frame. Keep the compost moist and transplant into the garden once the seedlings have established. Dig out a shallow trench and gently slide the pea seedlings into it. Water and cover with cloches to encourage growth. Autumn and early spring sowings will benefit from cloche protection.
Peas sown in cold, wet ground will rot so make sure the soil is warm. In early spring, cover the soil with polythene before sowing and then protect seedlings with fleece.
Sow seed in a single row 5 to 10cm (2 to 4in) apart, ensuring there is enough space for plant supports. Make a single V-shaped drill, 5cm (2in) deep, water the base of the drill and sow the peas. A second row can be added, as long as it’s 30cm (12in) away from the first drill.
It is important to have room to get between the rows to pick - 3ft is probably the minimum and 6ft is ideal. If using the latter spacing, a crop of radish or lettuce can be grown in the gap, to be harvested before you start picking the peas.
Water your peas well after sowing, and then leave them - except in very dry weather - until they flower, when they should have a really good soak to encourage good pod formation. Keep them weeded until well established.
All but the most dwarf varieties need support. Once peas have reached, 5 to 8cm (2 to 3in) in height and their tendrils begin to reach out for support, place supports next to plants. Use bamboo canes, pea sticks, trellis, netting, chicken wire or use any garden pruning that produces twiggy branches.
Regular picking is essential for a truly fresh pea. The more you harvest, the more they will produce. Harvest from the bottom of the plant working upwards. Do not pull up the plant as the roots are full of nitrogen-fixing bacteria. Cut off the stems at ground level, allowing the roots to rot down and release nitrogen back into the soil for the next crop to use.
Best eaten fresh, eat raw or boil straight after picking. Serve with just a knob of butter and a sprig of mint from the garden.
The tips of the vines and the top set of leaves of the pea plant are an Oriental delicacy. They can be served raw in salads, quickly cooked in stir-fries, or blanched and used in soups.
Peas can be stored in the crisper section of the refrigerator for 2 to 3 days. Freeze any excess pea harvest as quickly as possible because the sugar in peas turns to starch very quickly after picking, which destroys that precious sweetness.
Peas are a useful part of the gardener's vegetable rotation. Cut off the stems at ground level, and allow the roots to rot down and release nitrogen back into the soil. The nitrogen can be taken up by the crop that follows them - usually a brassica such as cabbage.
Peas are self-pollinating and so it’s very easy to save seeds for next year. However, don’t wait too long, especially if you have any mice around. Once they get a taste for dried peas, they’ll snag the lot. Try to wait until the pods have begun to dry out – the outer casing becomes much thinner and brittle. At this point, even if the peas inside are still soft, you can harvest the pods or even entire plants. The peas should be allowed to air-dry in a protected spot until they’re completely hard, at which point they can be safely stored for next year or for using in soup.
Peas come in two varieties: shelling and mangetout.
Shelling peas mature at different times. Earlies take around 12 weeks, second earlies take 14 weeks and maincrops take 16 weeks. While the slowest can take a month longer - they will then go on producing pods for about a month.
Shelling peas come in round and wrinkle-seeded varieties. Choose round seeds for hardiness and early sowings, and wrinkled for sweetness and summer sowings.
Mangetout is French for "eat it all" and comes from the fact that the whole pea - including the pod - is eaten. They are a frequent addition to stir-fry dishes. Other names include Snow Peas, Edible-podded peas, and Chinese sugar peas. They are without the hard wall to the pod that conventional 'wrinkled' peas have.
Mangetout and sugarsnap peas are eaten pods and all. The former never really develop proper peas, while the latter do, but slowly, which means that if you do not pick them regularly you can harvest the maturing peas and eat them as a normal variety.
Both are without the hard wall to the pod that conventional 'wrinkled' peas have.
There is a lot to be said for growing these peas if you have limited space and perhaps limited patience for shelling peas.
