Strawberries – fragaria x ananassa
This is, arguably, everyone’s favourite fruit and the flavour
is used in drinks, ice-creams, cakes, preserves and even medicines universally
as an irresistible flavour. That said, strawberries are really quite easy to
grow.
Sowing
and Growing
It is possible to grow strawberries from seed although you may
have to search for suppliers and the choice is limited. Sow in early spring
after a couple of weeks in the freezer which will improve the germination rate.
For most people, the easiest way to get started is with young
plants [runners] which will be supplied in pots from garden centres and seed
suppliers. If you want to establish a good-sized bed, this can be quite an
expensive way of getting started. Most of your allotment neighbours will have
established strawberry beds which will produce many unwanted runners each
summer. Have a chat with them and ask if you can take runners from their plots.
It is reasonable to assume you will have to do the work yourself and water
regularly in dry summers to ensure they establish in their pots. When they have
rooted firmly into the pots you can cut the stems to the mother plants.
It is probable that your neighbours won’t know what variety
they are growing but, if you choose good strong plants you are likely taking
from stock which is happy with the ground you will plant into. Once you have
established your own bed you can then use your runners to enlarge your bed and
create new ones.
In May/June/July - the plants will put out these runners [long
stems with one, two or even three young plants which will root into the nearby
ground to create new plants]. Unless you are planning to increase your stock or
set up a new bed, it is a good idea to clip out these runners as they appear as
they will take away from your ‘mother’ plants. Of course, as you remove them,
they will continue to put out new runners. You can use these runners for your
own use or to share.
It is recommended that you pin or peg these young plantlets
[the young plants as they appear on the runners – choose the ones closest to
the mother plant as they will be the strongest] into pots which you then bury
into the surrounding ground to prevent them from drying out.
In dry years they will have to be watered regularly anyway.
Being a lazy gardener, I prefer to take the strongest runners
from the strongest plants in the early autumn when they have already rooted
strongly into the surrounding ground. A few of these will fail but I will have
so many more to replace them. My chosen method is to take the young plants with
the best developed root structure which I will lift with as much of the root
area as possible and transplant them into the prepared bed.
To help reduce weeds I will cover an area 2 metres wide by the
width of my plot 4 – 5 metres, [it really isn’t necessary to have such a large
area but, I have the space and enjoy the fruit] which has been well dug and had
a very liberal dressing of well rotted manure [20 cm thick, at least] with a
woven fabric usually sold as ‘Weed Control Ground Cover Membrane’ or ‘Weed
Barrier Matting’. I pin this matting down securely, cut ‘cross’ holes in the
matting at approx 60cm apart and plant the young rooted runners into the
well-enriched ground beneath. Water well until the plants have established. The
matting will keep most of the weeds at bay unless perennial weeds have not been
removed beforehand. The matting will allow rain to penetrate to water the
plants although in very dry years some extra watering will be necessary.
In the spring clear off the previous season’s dead leaves to
ensure slugs and snails don’t have anywhere to hide and to keep the plants
tidy.
Strawberry beds should be replaced every three years. On the
first year, it is recommended that you don’t allow the flowers to develop
fruits though, I always do! In the second year the fruit should be at its best
– large luscious fruits - and in the third year you should have more berries
but, maybe not so large. Although you can continue to harvest from these plants
in following years, it is not really recommended as the fruits will become
increasingly small and insignificant. I find it useful to have two plots on the
go, so that I can always have a good crop [well, some very wet years have to be
the exception].
Types and
Varieties
Strawberries can be classified
by their time of harvesting or by type.
·
Alpine strawberries frageria vesca – usually much smaller than their more cultivated cousins
– they can be a bit sourer but are exquisitely flavoured fruits.
·
Cultivated Strawberries
§ early
season – Christine [ can harvest from May in warm areas or from under cloches],
Sweetheart
§ mid
season – from mid-June - Cambridge Favourite, Malwina, Sonata, Royal Sovereign,
Malling Opal [will produce fruit from June until October
§ late
season – Elegance, Malling Opal
§ Everbearer
/ all season – there has now been developed a range of plants which will
produce fruit from June until autumn – eg. Malling Opal, check the seed houses
to see what has been recommended.
Harvesting
and Storing
Blackbirds just love strawberries and will go around your
ripening fruit eating the red patches out of them before they have had a chance
to properly ripen ready for harvesting. I find this a problem only at the start
of the season when I am looking forward to my first fruit of the year. After
that, I feel there are enough to share with them. If you are trying to beat the
blackbirds try harvesting slightly before they are fully ripe, they will
continue to ripen over the next 24 hours, even in the fridge.
Strawberries really are best eaten fresh, enjoy them while
they are fresh as it will be many months before they are available again. They
won’t keep for long in the fridge – 24 hours maximum.
Although it is possible to freeze them, it isn’t particularly
successful as they will turn to mush when defrosted.
However, if you are determined, try putting 1 berry into each
of the sections of an ice-cube tray, fill the section with water and freeze.
They can be left in the trays for a short time or for longer storage decant
them into a freezer bag. Alternatively, place the dried, hulled berries onto a
tray, making sure the berries are not touching then, freeze. When well frozen,
the fruits can be stored in a freezer bag.
If you have more fruit than you can happily eat fresh or –
heaven forbid you might get tired of eating them – they do make the most
wonderful jam and conserve - see below

Pests and
Diseases
Slugs and Snails – slugs and snails can be a
serious nuisance with these ground growing plants, especially in damp weather.
The pests will hide under the dense leaf growth during the day then, come out
at night to destroy your harvest. Use slug pellets, beer traps or nematodes.
Botyritis [grey-mould] – this is usually only a serious
problem in damp warmish weather although a few fruits may be affected, even in
dry years. Pick off and remove any affected fruit before the spores can affect
other fruit. Keep weeds under control and avoid overcrowding the plants.
Birds – the best protection for your crop is to net
it. Keep the net off the ground and high enough for you to get inside for easy
picking. It can be a nuisance if you have to remove the net each day when you
want to pick your fruit. Allow an escape route for birds who will, almost find
a way in despite your best efforts. It is most distressing to find the remains
of a bird that has been caught by the net or trapped by a predator.
Strawberry Jam
2kg ( 4lb) strawberries
1¾ kg ( 3½ lb) sugar
Juice of half a lemon
Method
1.
Hull the
strawberries and wash only if really necessary ( it is important that no more
liquid is added to the fruit).
2.
Put the
strawberries into the preserving pan with the lemon juice and heat very slowly
until the fruit is really soft and has released much of its juice. ( 20 minutes
or so).
3.
Add the sugar and
stir over a gentle heat until you are sure that all the sugar has dissolved.
4.
Bring it to the
boil and boil briskly until setting point is reached – test a little on a saucer or use a sugar
thermometer.
5.
Leave the jam in
the pan for 10 – 15 minutes until it has cooled slightly. (when it has cooled
slightly the setting process has started and this prevents the fruit rising to
the top.
6.
Heat sterilised
jam pots then place them on a wooden surface to pot the jam.
7.
Pot up the jam,
cover and label.
( my
personal preference is for the jam to be only lightly set, I think it has a
better flavour.)
Strawberry Conserve
There are many recipes for strawberry conserve and all
saying much the same thing. This particular one is from ‘Allotment Growing
Recipes’ – www.allotment.org.uk
2lb (1kg) small strawberries
or halved, hulled larger strawberries
2lb (1kg) granulated sugar
Juice of 1 lemon (or 2 Tblsp
bottled lemon juice)
·
Place alternate
layers of strawberries and sugar into a bowl.
·
Add the lemon
juice, cover and leave to stand overnight – 12 hours.
·
Next day, transfer
the fruit and the sugar to a pan, bring slowly to the boil and simmer for 5
minutes.
·
Pour back into
the bowl, cover and leave again for another day.
·
Finally, transfer
to a pan, bring to the boil and simmer until setting point is reached.
·
Remove from the
heat and leave to cool a little (until the fruit begins to sink in the syrup).
·
Stir and pour
into small, hot, sterilised jars and cover immediately. Label.
