I’m always looking forward to October. It’s usually quite a dry and
beautiful month and the colours are amazing. Unfortunately the
beautiful autumn leaves don’t usually last long here in the west – a
couple of seasonal gales and they are gone.
At the recent Ploughing Championships we (Environmental Pillar) we
launched the People4Soils campaign. I’ll have an additional newsletter
on this once the online petition is open. In the meantime if anyone
would like to support European campaign that will provide a legal
framework for soil protection and to help us create an awareness that
we need to protect our soils, please contact me on firstname.lastname@example.org
Klaus Laitenberger Saturday 8th October
This talk will help you prepare for the next growing season. Good
planning is half the work done. Tips on how to bed down the garden for
the winter, improve soil fertility and develop a crop rotation. Klaus
will help you choose suitable crops and varieties and how to make a
sowing plan for the following year.
Venue: Botanic Gardens, Glasnevin, Dublin

What to do in October
October is the month to fill your larder. Many crops are harvested and
stored safely for the long winter months. It’s also the month to put
your beds to bed for the winter. As the ground becomes vacant after
harvesting crops you can put the beds to rest for the winter. A thick
cover of fresh seaweed is ideal. If you can’t get any seaweed you
should either cover the beds with strong black plastic or grow an
overwintering green manure crop. The most efficient method is to
prepare the beds and work in some compost and then cover the beds
securely with black plastic. You will have very little work to do in
the following spring. It is advisable to get as much of this work done
before the weather turns unpleasant.
Stake tall brassicas such as kale, Brussels sprouts and purple sprouting
broccoli to prevent them from rocking and collapsing in the wind.
You may think it’s far too late to sow any vegetables so late in the
year. In actual fact it is the ideal time to sow your overwintering
broad beans and to plant you overwintering garlic and onion sets. Just
make sure that you use suitable varieties. October is still a good month
to sow green manures. You can sow grazing rye, vetch and field beans.
Harvest all your maincrop potatoes. Dig them out carefully, let them
dry for an hour and then store them. Never wash them before storage.
You can also dig out your carrots and beetroot and store them in boxes
of damp soil in a frost free shed. The firm Dutch cabbages should also
be harvested and stored in a cool shed but not in sand/soil. Celeriac,
parsnips, leeks, savoy cabbage, kohlrabi, perpetual spinach and swede
can be harvested as required. They can be left outdoors as they are
very hardy. However, if your ground becomes very waterlogged in winter
you better dig out your parsnips, swedes and celeriac at the end of the
month and store them in boxes indoors. The first Brussels sprouts may
be ready by now. The runner beans are probably finished by now. After
your last picking you can clear the plants. It helps if you chop or cut
the stems before putting them on the compost heap. If you leave the
roots in the ground the nitrogen rich nodules will stay in the ground.

Growing Yacon (Polymnia sonchifolia or Smallanthus sonchifolia)
Yacon is really one of my favourite vegetables to grow. It originates
in the Andes and was one of the lost crops of the Incas. It is closely
related to the dahlia and produces large edible tubers that even
resemble dahlia tubers. In a tunnel or greenhouse it can grow into a
large plant and produces a very high yield of sweet tasting tubers that
can be eaten raw or cooked. Even outdoors it grows very reliably even in
Leitrim. It could become one of the new superfoods as its
carbohydrates are not stored as starch but as inulin and could thus play
an important part in a diabetic’s diet. Apparently yacon leaves were
used by the Incas as toilet paper.
Soil and site
Yacon requires a free draining, fertile and well balanced soil and should be grown in full sun.
Sowing and Planting
Yacon can only be grown from stem tubers. Yacon plants have two types
of tubers – very knobbly ones that cluster around the stalk and
beautiful, large, smooth and succulent tubers that grow outside of the
knobbly ones. Obviously the smooth succulent ones are for eating and
the knobbly ones for propagation.
The knobbly tubers can be separated in the dormant season and provided
that they have a growth point will make a new plant. Each part should
be potted on into a 1 or 2 litre pot depending on the size of the tuber
using good potting compost. The pots should be placed in a cool
unheated but frost free shed over the winter and from early April (or as
soon as growth start) placed into the greenhouse bench or a
south-facing window sill in the house. The plants can be planted into
the tunnel or greenhouse around late April or in May outdoors.
The plants grow huge with a spread similar to a courgette plant and a height of about 1.5 to 2 metres.
Between plants: 1 metre
Apart from regular watering there is no additional maintenance required.
Harvesting and storing
You should leave the plants in the ground until the first frost has
killed of the leaves. The tubers seem to grow a lot during the end of
the season so the later the first frost, the higher the yield. The
yield of tubers can be truly phenomenal and no other vegetable can match
it. In one year I got 8 tubers each weighing nearly a pound.
Carefully dig out the whole plant and remove the smooth succulent tubers
and use them immediately or store them in moist sand in a frost-free
shed. What is left is the knobbly part of the plant. Store that in a
bucket of moist sand or soil in a frost-free shed. This can be split up
in the following spring and you can give some new plants to your
The tubers are delicious raw and cooked. When eaten raw they have a
surprisingly sweet taste. When cooked they remain crunchy and can be
used as a potato alternative. They are also delicious roasted.
One of the advantages of ‘new’ vegetables is that they are often free of
any specific pests and diseases (the potato was grown for centuries in
Europe without blight!). Apart from the occasional slug nibble on the
leaves they grow completely healthy.
To my knowledge there are no named varieties of yacon.
We have a very small number of yacon plants available now on our
website. Each plant has a few growth points. When the plants arrive
pot them on into a 1 or 2 pot and keep in a cool but frost free shed.
As soon as growth starts in spring place the pot in a sunny place
(greenhouse or south-facing windowsill) and plant into the greenhouse in
mid April or outdoors in May.
