TIME TO PLANT POTATOES
Lifting early International Kidney |
Potatoes have always
played a major role in feeding the nation, and we gardeners always allocated a
big portion of our allotment space to the humble spud. It was our staple diet
and used daily as boiled, baked, roasted, mashed or as chips or even fritters.
Life moves on as we try to live a healthier life style and we now have access
to a much wider variety of foods including rice, pizza and pasta and numerous
healthy green vegetables, so our humble spud takes on a lesser role.
In my youth we grew a lot of the variety Majestic as it was a huge tuber that was perfect for chips. Today we (well, some of us) don’t eat so much chips so a variety that produces small potatoes is just as important as we can use them in salads. I practice a four year rotation on my plot so potatoes take up one of these sections each year. I grow a range to suit my own needs which is one really early variety, Casablanca, a second early salad type, Charlotte, with Sarpo Mira, a heavy cropper with good blight resistance, as my maincrop. I am also trying Genson and Amour as they get good reviews and it is always good to try something different.

Planting a row of potatoes |
Other good potatoes to
try include Lady Christl a very early variety, Desiree a maincrop and Maris
Peer an excellent small salad type and its bigger brother Maris Piper a great
spud for chips.
Purchase seed tubers
only from Scottish or Irish sources where very strict hygiene conditions ensure
the crop is clean and gets the highest certification. This information will be
shown on labels on all bags purchased.
If you are tempted to
retain seed potatoes from your own healthy crop, only do so for one year and
only if the crop was very clean and free from blight and any other pest or
disease. Never accept seed potatoes from a friend as the risks of potential
infections are too great.
Potatoes are heavy
feeders so grow best on land that has been well manured in autumn and left
rough over winter.
It is a good practice
to chit early varieties as it gives them a head start. Place the seed potatoes
upright, (rose end upwards) in trays or egg boxes and leave in a light frost
free position for a few weeks to get them to sprout.
Planting time is very
much depending on weather, so in a mild period it could be early to mid March
for the first early varieties, otherwise as soon as you feel there is some
warmth in the ground.
Earlies are spaced
about 12 inches apart along the rows which are 18 inches apart. For maincrops
increase the spacing to 15 inches apart with rows 2 to 2.5 feet apart.
Take out a furrow six
inches deep and run some well rotted compost along the bottom. Cover this with
some soil and plant into this. Cover the rows but leave a slight ridge to mark
the line, and then give a dusting of potato fertiliser high in phosphates and
potassium.
Potato flowers |
Once the foliage
emerges keep an eye on the weather and if frost threatens earth over to protect
them. Continue to earth over as this kills weeds and creates a friable
structure.
Lifting can begin at
the start of June with first earlies and continue till October for lates. Lift
on a sunny day and leave the spuds to dry on the surface for an hour or so.
Discard any tubers that show any greening as this contains poisons. Potatoes
are best stored in the dark in hessian or paper bags in a frost free shed
protected from mice.
Wee jobs to do this week
Continue with
outdoor sowing of leeks and indoor sowing of sweet corn. I sow leeks thinly
outdoors in a fertile well prepared seedbed, where they can grow strongly for a
few weeks prior to lifting and transplanting.
Sweet corn is sown
at the end of March indoors in cellular trays (40 cells/tray) and kept warm to
germinate then transferred to my cold greenhouse to grow on. Once they are a
decent size I pot them up into individual 7cms pots and grow on for a few more
weeks before hardening off for transplanting at the beginning of June.
