  • Grow at Home: Spinach

    Growing Spinach

    Spinach_seedlingsYou will have heard (maybe from the lips of the legendary PopEye) that spinach is super high in iron.  This, and the rumor that a scientist put the decimal place in the wrong spot thus multiplying the iron content by ten, both appear to be unsubstantiated and probably false.    However, spinach is an excellent source of vitamin K, vitamin A, vitamin C and folate as well as being a good source of manganese, magnesium, iron and vitamin B2.  It is also tasty and versatile and can be used from smoothies to stir fries to salads. Oh, and its easy to grow!

    Sowing & Harvesting

    Sow your seeds directly outside in their final positions from March to August. Sow them in shallow lines quite thinly. Cover them with poly tunnels or cloches to protect them and to encourage growth, you may also need a Slug-Buster.  If you don't have a large garden then spinach will also thrive in a container. Choose a Shallow vegetable planter -as spinach doesn't 't have long roots - and plant thinly exactly as you would outside.

    As the seedlings appear, thin them out to about 6-8” 15-20cm apart. You can pick the smaller more tender leaves when they are about 3” 7cm long and use them in salads, anything bigger than that should be cooked for a short amount of time and be eaten as a hot vegetable.

    Keep picking the leaves so that a) they don’t run to seed and b) they keep on growing.

    tiny_spinach_plants_in_groundPerpetual Spinach is the one that I always plant as you only need to plant one lot and it lasts for months and months, sometimes even years.  Very easy. Perpetual spinach is not actually spinach but looks and is eaten in exactly the same way.  Well worth planting for a regular supply.

  • 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.

    spring_onion_cutThey will germinate without extra heat, but providing a little heat underneath the seed trays or pots will speed up the germination process.  So, add a lid or enclose in a plastic bag and put it on a heat mat or somewhere warm like on top of the fridge.  Germination should take around 7 to 10 days.

    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.
