On
the Allotment in August
Already I am thinking of the end of summer. Shops
are advertising ‘Back to School’ sales for school uniform and essential
equipment for children who have only just started their long awaited summer
break. It seems so unfair and the summer is passing much too quickly, as it
does every year.
Maintenance
around the plot and in greenhouses or poly-tunnels –
-
Keep the plot tidy - cut grass on paths regularly to prevent weeds and grass
from encroaching on your plot and to reduce slugs and snails.
- Weeding – keep all beds, free from weeds. Hoeing
is useful but take care to not damage young plants [hoeing is not very
effective in wet weather as the hoed weeds will often re-root]. Pick up plant
debris and compost or dispose of as rotting leaves will encourage pasts and allow
diseases to develop.
- Keep fruit cages tidy and weeded – for
particularly vulnerable bushes like redcurrants and gooseberries, ensure the
cages are secure although do allow an escape hole for those intrepid birds
which find a way in, in case of predators – cats and foxes will force a way in
to catch trapped birds.
- Watch for pests like caterpillars, whitefly,
aphids on developing brassica plants and beans, especially in dry weather. Snails
and slugs will happily eat your plants, even in dry weather
- Water ‘thirsty’ plants in dry weather – curcurbits
[courgettes, cucumbers, squash and pumpkin], brassicas like cauliflower and broccoli
as the curds and sprouts are developing.
- Cut back perennial herbs like mint, sage,
marjoram/ oregano to encourage a new flush of growth. Clumps of chives can now
be divided. Keep a pot at the back door for easy harvesting [I find that my
clump on the allotment is rarely harvested as it is a herb need instantly to
enhance dishes rather than for pre-planning a trip to the allotment.
- Cut out the tops of climbing Runner and French
beans to encourage the pods to develop within reach. Harvest regularly, even if
you don’t want them, to ensure the plants continue to produce new pods [give
them away if you have too many but, if necessary, compost the excess.]
- Check on developing squash and pumpkin plants and
limit the number of fruits to 3 or 4 except on the varieties with very small
fruits [ eg Baby Bear, Tiny Tim, which can successfully ripen more].
- Remove all spent raspberry canes and place in
long-term composting facility or set aside for burning from November. Tie in new
canes to protect from wind damage.
- Tidy spent strawberry beds.
- Prune blackcurrant bushes as soon as all fruit is
harvested
In the Green house or polytunnel
- Keep green-houses and poly-tunnels well watered
but ventilated to prevent botrytis [greymould].
If you plant green-house/ polytunnel crops straight
into the ground, it is a good idea to aerate the ground around the plants occasionally
[I use a fork] being careful to not disturb the roots of the plants. Over the
season the watering can create a ‘glaze’ or hard crust on the surface of the
soil, preventing water and feeding from penetrating the ground. In my opinion, it
is better to water thoroughly every 2 - 3 days rather than a little every day
which encourages shallow roots
-Pinch out the tops of tomato plants as the trusses
start to set – allow only 5 – 6 per plant. Continue to remove side shoots as
they develop [except on bush tomatoes]
- Remove the growing tips of aubergines to encourage
branching. As fruit start to develop, some support may be needed.
- Watch for pests like, ants, red-spider-mite,
aphids, caterpillars on tomatoes and deal with.
Feed indoor plants regularly as fruits are
developing – creating your own liquid feed is good using comfrey [my friend, Pete swears
by the trimmings/ prunings off the tomato plants as being excellent food for
tomatoes], Comfrey alone may be lacking in trace elements – eg magnesium. If
you are using a bought-in fertiliser, a general NPK fertiliser may not be what
you need as they are usually high in nitrogen which is excellent for leafy
plants. You will need a fertiliser which is high in potassium for good flower
and fruits growth but also has iron and magnesium for healthy plants.

Preparation and planning
-
Dig over beds as soon as crops are harvested, to create a good workable tilth -
ready for the next planting or in preparation for the autumn digging cycle [ I
have found that I don’t have enough days when the weather and ground are
suitable during the autumn for me to ensure all of the cleared beds are dug
over so, starting as early as possible – even if they develop a weed harvest,
is better than leaving them]. The difference between autumn digging and spring
digging on my heavy clay soil is amazingly significant.
-
From October onwards perennial plants you may wish to establish on your plot
will be available from the major seed houses – rhubarb, asparagus, [ October /
November for autumn planting varieties], fruit bushes and trees, [end of
October to March – their dormant season], etc. Plan what you want to buy and
where you want it to grow, remembering that perennial crops may be in situ for
many years. Check on the needs of the plants and prepare the planting areas
thoroughly. Think carefully about the varieties you wish to grow – will they
suit your location, soil, etc.
-
Start potting-up strawberry runners for establishing new strawberry beds. IN
dry weather these plantlings, although hardy and still connected to the ‘mother’
plants, will need regular watering to establish well.
Sowing and planting
-
Continue to sow salad crops – lettuce can
be sown until the end of September, although with decreasing success as the
season progresses. Cut-and-come-again crops are particularly useful in large
tubs in the back-yard. Similarly rocket can be sown until the end of August.
Radishes, of course are still an excellent crop, especially for the Winter
varieties which will provide a harvest throughout the winter.
-
You can continue to sow appropriate
varieties of carrots but cover with environmesh to deter carrot root fly [a
real problem on allotments].
-
Cabbages – Spring cabbages can be sown
[but do sow outdoors – keep the seedbeds well watered and free of slugs] until
the end of August. Then plant into their permanent beds as soon as the plants
are strong and have 6-8 true leaves. I have found it useful to plant a side of
my poly-tunnel with these cabbages which will give me a harvest when there are
few other vegetables available. My Favourite is Frostie F1 but, other growers
have other varieties just as successful.
-
Sow a crop for late potatoes [specially
developed for late cropping – see the selection of your favourite seed houses].
This is now a popular development of the potato crop – providing a harvest of ‘new’
potatoes for Christmas. It is important that you provide adequate frost
protection as potatoes are very sensitive to cold weather. I have tried this
once and all of my crop was hit by an early frost as the young plants were
emerging. Although I didn’t get a Christmas crop, the plants did produce an
excellent crop the following spring.

Harvesting –
the best part of growing!
-
Finish harvesting Second-Early potatoes and
Early-Main-crop potatoes should be well developed. Some main-crop potatoes may
also be ready as the top growth yellows and starts to die back. Allow the tubers
to dry overground [if possible – don’t leave them long enough to become green
as this green potatoes are toxic] before bagging up and storing. Store in
hessian or paper sacks in a cool, dark, dry environment.
-
Globe artichokes are still harvesting.
If you have lots of them and are tired of eating a heavy harvest, try freezing
the hearts.[This is the first year I have tried to do this and will get back on
the success of this procedure].
-
Beans – broad beans are coming to
the end of their harvest. The bean waxy skins become quite unpleasant as the
season progresses and it is necessary to peel the separate beans. Many people
find this not worth the trouble but, if time is taken, they still make and
tasty and nutritious vegetable. French beans and Runner beans are now
into their stride and for me at least, are providing far too many beans. I am
hoping to share with neighbours and friends though, I suspect, I will still
have far too many. This year I have grown five different varieties [I’m always
afraid I won’t have enough!]. Two of the varieties I’ve planted are for drying
for winter use but, the other 3 varieties are being much too prolific.
-
Onions, shallots and garlic will now
finish their growth – look out for yellowing leaves and some withering. In
onions, the leaves will fold over. Lift them and set them on the ground, in dry
weather or on a rack, to allow them to dry out before storing in a cool dry
place. Similarly for garlic. Ensure the plants have dried thoroughly before
storing.
-
Soft fruit – most soft fruit -
redcurrants, blackcurrants, white currants and gooseberries are coming to an
end of their useful harvesting period, depending on the variety.
-
Some varieties of plum, pear and apple
are now ready for harvesting.
