and How To Plant Potato Seed
Potatoes are grown from 'seed' potatoes which grow better if they are
allowed to 'sprout' before planting.
First purchase the seed potatoes in
late January. These are
available from seed catalogues or your local garden centre. Look for
seed potato which is certified as free from disease and select
healthy looking examples about the size of an egg.
||The disadvantage of the catalogues and garden centres is that
the number of potato seed varieties is very limited and they are
only sold in large amounts. If you only want more variety and to
buy several varieties in small amounts, the solution is to go to
one of the many potato shows around the country.
For an idea of a
typical show and prices etc.
mid February, place
the seeds in boxes (for small amounts, cardboard egg boxes are ideal) in a light airy position at a temperature of roughly
10°C / 50°F. See right.
The potato seed should be positioned so the the sprouts are uppermost and the
'stalk' end (where they were severed form the parent plant) is at the
bottom. Sometimes this is a bit difficult to judge, but if you get it
wrong, and the potatoes sprout from the bottom end, simply rub off the
sprouts and turn the potato to the correct position. The picture below
shows the stalk end of a potato which should be at the bottom when placed in the egg boxes.
potato seed produce sprouts, remove all but the
topmost four to ensure that they receive all the goodness of the seed potato. The ideal sprout length at planting time
is 2.5cm / 1in
although this is not critical. What is critical, is that the sprouts are green and not
white coloured. White sprouts are caused by not enough light. Click the picture to enlarge.
If the sprouts appear too early for planting the
potatoes outside, simply rub them off cleanly and they will re-sprout in
a couple of weeks time. Research has shown that the sprouts can be
removed five times without any ill effect on the sprouts which will replace them.
is the ideal time to plant the sprouted
potatoes in the open ground. Plant 'earlies' about 30cm / 12in apart from each other, in rows
which are 60cm / 2ft apart. Plant maincrop potatoes about 35cm / 15in
apart, in rows which are 75cm / 2ft 6in apart. Where you are planting
more than one row, the rows should (ideally) run from North to South to allow each
plant its full share of sun.
Dig a trench about 10cm / 4in deep, placing the potatoes
in it with the sprouts pointing upwards. Hand fill the trench over the
potatoes trying to avoid damaging any sprouts. Scatter bonemeal or
similar long lasting fertiliser over the top soil and rake it in.
How to Grow Potatoes For Christmas Eating
In many areas it's quite possible to grow your own potatoes
for eating in October through to Christmas. Potato plants produce good
sized tubers in 65 to 100 days depending on variety.
for a separate page on how to plant potatoes in August.
Caring for Your Potatoes
Frost damage is the first concern in the early stages. If shoots emerge
above the soil level and frost threatens, draw a little soil from the bed edges over them.
the potatoes plants have grown to about 20cm / 8in pull up the soil in
between the rows around the plants leaving a few centimetres still
showing. Repeat the exercise in two to three weeks time. The diagram to
the right shows the ideal end result (click
here to obtain an enlarged picture).
During the growing season, ensure that weeds are removed and apply some long
lasting fertiliser again around mid-August. A month or so after planting,
the dense foliage of the plant should then block out sufficient light to
deter all but the most vigorous weeds.
As the potato plant grows, do not remove or 'stop' the
foliage, it is supplying food to the tubers. However, remove any flower
heads or buds which appear because these will produce potato seeds which
will divert energy from the potato tubers.

Message: When the potato plants start to produce flowers it is advisable to remove the flowers early to prevent the tubers from losing the food so far accumulated within them.

Message: As my small garden is largely a tiled patio, I am attempting to grow potatoes in a large tub with quality soil- bag earth.
The plants have a good crop of green leaves and I am wondering if they need much watering as we have had very little rain? Many thanks!
