  • Grow at Home: Onions from seed

    Many people grow onions from sets - mini, immature onion bulbs - to get a head start.  The advantage of growing onions from seeds, instead of from sets, is that it is far cheaper if you are going for a big harvest. So if you eat a lot of onions then seeds are worth a try but you need to get them in ASAP now.

    Sowing

    Make sure you use fresh seeds as the germination rate reduces the older seeds get.  They will still germinate but if you are using a packet from last year you may need to sow a few more to get the crop you are hoping for.  Sow the seeds on a windowsill or in the greenhouse, from February to April.

    Onion seedlings sometimes have trouble shedding the seed husk and end up doubled up like an ostrich with their head in the sand.  If you want to help them move along then you can snip the thinner bit, pull it out complete with seed husk and discard it.  The thicker side of the loop can then get on with growing.  This is fiddly and they will sort themselves out eventually so you can decide if you have the time and energy to do this or want to just let them get on with it.

    Whether you are growing in the ground or containers make sure that that the young onions get plenty of light. If you are not growing in a greenhouse, then put the seedlings outside on warm sunny days to get maximum light benefit and to help harden them off. Use a large Bell cloche, poly lantern cloche or poly tunnel to help protect from wind and temperatures below 10˚c. Once you are happy that night time temperatures are well above 8˚C then the onions can stay out without protection.

    Planting Outside

    onions_growingTransplant them outside in May or June when they produce a third leaf and are about 3” (8cm) high. Dig some rich fertiliser into the ground where you are going to plant them.  Make sure you put it directly under where the onions will be as their roots are concentrated directly down from the bulb.

    Plant them vertically and handle them gently. The bulb should be ½” (1cm) below the surface. Depending on the onions final sizes, plant them between 2-10” (4-25cm) apart, with 9" (22cm) between rows.

    Container Growing

    If you want to grow onions in containers then transplant them at the same stage as for outdoors. The container will need to be at least 10" (25cm) deep and each onion will need about 8cm (3 inches) of space to grow. So, the wider the container the better.  Make sure that the compost you use to fill the container is not too high in nitrogen.  If it is you will get a lovely leafy display above ground and very little below ground.

    Looking after your Plants

    The important thing while they are growing is to keep the weeds down.  Onion seedlings don't compete well with weeds and it will affect the size of your onions.  So weed regularly.

    You can also keep trimming them back to around 5" so that they don't flop over.  Once again they will be OK if you leave them to their own devices, so if you're not growing them for the Village Show you may want to miss this step.

    Keep them well watered especially when it is dry. When the leaves start to turn yellow at the ends, bend the tops over to help with the ripening.  Possibly even clear a little of the soil at the top of the bulb too.

    Harvest

    onion_bulb_in_groundHarvest them from July to October.  Lift the onions as you need them from July to October.  There is a danger that they can rot in the ground when it starts to get very wet so harvest and store them before the end of October. After you lift them let them lie in the sun for a couple of days.

    Storage

    Only store the onions that are perfect - use any that aren't straight away.   The best way to store them is in a jute Veg Sack.  This allows air to circulate and keeps them cool and dark. They can keep in a well aired room for up to six months.

    Top Tip

    When peeling chopped onions, light a couple of candles.  This should stop your eyes watering, as the vapours from the onions will be absorbed in the candle flames.

  • Grow at Home: Peas

    There is nothing quite like the taste of freshly picked peas especially in a home grown salad. The moment the peas is picked its natural sugars start to break down into starch, which affects the flavour. With careful planning and by using a range of varieties, peas can be harvested from late spring until late Autumn.

    Where to grow

    Grow peas in fertile moisture retentive soil. Dig to a good depth in the Autumn and incorporate plenty of well rotted manure or garden compost. Avoid areas that may become waterlogged – the plants will rot at the base if too wet.

    As with most crops, peas do best in a sunny open spot, but they will tolerate light shade.

    Sowing

    Varieties such as ‘Fetham First’, categorised as first earlies, are smooth skinned, while second earlies and main crop, such as ‘Onward’ and ‘Alderman’ have wrinkled skin. First earlies can be sown outside in mid to late Autumn and overwintered under cloches to protect against frost.

    Peas do really well when started in Rootrainers before being transplanted outside.  This gives them a super strong root system  which allows the plants to produce a bigger crop of delicious peas.

    Sow main crop varieties at regular intervals from early spring to mid Summer and will not need protection unless there is a period of prolonged frost.

    Sow double rows in flat bottomed trenches 23 cm wide and 5 cm deep with 50cm between trenches.

    Or for a 'no dig' solution use a planter specifically designed for peas - the Haxnicks Pea & Bean Planter. These planters are reinforced with rigid tubes and have 6 cane pockets to hold canes in place without disturbing the soil.  They are ideal for those without space in their garden who still want to grow their own veg..

    Aftercare

    Immediately after sowing protect the crop from birds by covering with wire netting or twiggy branches over canes or using the Haxnicks Birdscare.

    Provide support using pea sticks or netting when the crop reaches around 8cm high. For tall varieties place the supports on either side of the growing stems. Water regularly during dry spells especially when the plants are in flower. Mulching with garden compost will help with moisture retention.

    Harvesting and Storage

    Harvest when the pods are plump but not fully grown, picking from the bottom of the plant and working your way up. Keep picking to encourage production of more pods.

    If you are growing Mange Tout or Sugar Snap varieties pick on the early side to ensure the pods have not become tough.

    Peas are best eaten straight away, but will also freeze well in container or can be left to dry in their pods – wait until you can hear them rattle – and stored in an airtight container to use in stews or soups.

    Pest and diseases

    Peas are prone to a number of pests and diseases. Pigeons and small birds can devastate young crops – Micromesh netting is the best protection. Mildew can also be a problem. Pea and Bean weevil can cause stunting of plant growth.  The crop may come under attack from Pea Thrips too in hot sunny weather. Silvery patches are seen on the pods and leaves which will affect the yield.  Pea moth can also be a problem.  The adults lay their eggs when the peas are in flower – sow early or late to avoid the moth’s flying period.
