From
the mysterious outback of Iran comes a very interesting, yet often
neglected, vegetable called spinach. (Well it's also native to
Manchuria and South-West Asia, but Iran sounds more exotic). Anyway,
unlike Iranians, spinach comes in five different sexes, which you'll
only discover when they flower. These are: ordinary males; extreme
males which are usually short; females that produce the seed;
hermaphrodites with both male and female flowers (illegal in Iran); and
extreme, vegetative males which produce no flowers (possibly due to
laziness).
You may not actually want to know that
information, but it is something new, and you should always learn
something new every day. If you want more information on saving seed
for spinach, better go visit the Seed Savers'
website listed at the side of the page.
If you just want to grow spinach, then read on.

Cultivating
Spinach
One thing to always remember when cultivating
spinach is that it hates heat. What does it do when it gets hot? It
starts going to seed and stops growing lovely leaves for you to eat.
So, if you have a hot summer you might want to consider growing Australian
Spinach (also called New Zealand Spinach), which grows
prostrate along the ground and is very drought resistant or Ceylon
Spinach (also called Malabar Spinach), which is actually a
type of vine, with red stems and large succulent leaves, native to
southern India that you can train over trellises and pick to you hearts
content. The roots of the plant are also used as a treatment for
diarrhoea in China. Neither of these spinach are "true" spinach.
"True" spinach seed should be sown directly into
the ground (around 15-25 cm apart) where it is to be grown in: very
late autumn/ early winter in sub-tropical climates like Byron Bay and
the Gold Coast, Australia; late autumn/ early spring in temperate/ warm
climates like Sydney, Australia; and early spring and through the
summer in cool miserable climates like London, England, Sligo, Ireland
and in Iceland.
You can grow baby spinach in
hot summers by planting closer together under some sort of shade cloth
and harvesting very young. You can do the
same with lettuce in these climates.
Bloomsdale
Spinach
As you may have noticed when washing spinach
bought from a market, spinach is often grown in coarse, loose soils and
it doesn't tend to like really hard surfaces. It does however like very
rich soil with a high nitrogen content (add lots of well broken down
compost + animal maures). For the home gardener I can suggest growing
the stuff in large pots filled with good organic potting mixture, and
perhaps a little blood and bone and some liquid seaweed fertiliser.
Plant every few weeks during the right season so you can have a regular
supply over a long period of time. You can also steam and freeze the
excess for use later on. Never allow plants to dry out, it is the
second most cause of failure behind heat.
What
types of spinach are there?
Some types of spinach available are Long
Standing Bloomsdale, Victoria, Japanese Soshu
(very fast growing), Broad Flanders, Savoy Leaf, Elephant Ear and
English Spinach.
So sow your own spinach and reap the benefits of firm
and vibrant leaves which will make you glad you did so. If you want to
buy Australian Spinach or Ceylon Spinach, I recommend Eden Seeds (if
you are in Australia), otherwise true spinach seed is available quite
widely.
