SWEET CORN
August is a great
month for healthy eating as the garden and allotment are at the peak of the
harvesting season with a huge variety of fresh fruit and vegetables. Sweet corn
tends to ripen all at the same time so harvesting the cobs is a once over task.
However, to know when best to cut the corn, sampling is done every few days to
test the softness and sweetness. Sample when some of the cobs tassels have
turned a dark brown colour. Push your
fingernail into the corn and if it is
watery it is not ready, as it should be milky when tested, but if it is left
too long it will go pasty. I tend to pick a few cobs to sample for the table
about two weeks before final harvest. The corn has a high sugar content at this
stage, but the sugar is slowly converted to starch if harvesting is delayed.
However for folk watching the calories, one cob has less sugar than an apple
and only half as much as a banana. Some newer varieties have a higher sugar
content known as super
sweet and are delicious to eat fresh straight off the
plant. The sweetness in the corn is created by a recessive gene so keep the
sweet corn block well away from other sweet corn plants otherwise cross
pollination may cause loss of sweetness and make the cobs chewy.

Sweet corn has
amazing health benefits both as a freshly eaten cob straight from the plant and
also when cooked as many of the benefits are enhanced. They are rich in phytochemicals that promote healthy vision, rich in
vitamins B and C, plus the minerals iron, magnesium and potassium. They are
also rich in fibre which feeds the good
bacteria in your gut, and aid digestion.
Culture
Sweet corn is still seen as a novel
crop in Scotland though it has been grown here by amateurs and
farmers for many
years. Our soils and climate (most years) are perfect for its growth and
cropping, and this year my plants (variety Incredible) are huge with some
showing a third cob on very vigorous plants. To get a strong and vigorous
plantation grow on well manured and fertile soil. As planting is most often done
in June, there is plenty of time to dig over the plot in winter adding plenty
of compost and leaving the surface rough for winter weathering. In early spring
break down the soil, rake level adding some fertiliser then sow down a fast
growing green manure crop. This will add humus and assist drainage. Trample
this down before it flowers probably in early to mid May then dig in the green
manure. This will give it time to begin to rot down before planting then it
will release its nutrients while the sweet corn grows. Sow seed indoors
individually in cellular seed trays in mid March, then pot up into bigger pots
when the plants are about six inches tall. Harden off in May then plant out in
early June, but all depending on prevailing weather. Plant about two feet apart
in square blocks to assist wind pollination. Give them
wider spacing if you
grow then together with pumpkins in the same block. Keep weeded and water in
dry weather.

Wee jobs to do this week
Rhubarb crumble and jam |
Rhubarb is growing very strongly now that the rain has
returned and the plants have had really warm weather, so keep pulling off good
stems for immediate use or if the crop is heavy it can go into the freezer for
future use. Give the plants a feed to boost more growth as there is still time
to pull more stems off before the plant slows down in autumn. Brilliant for
crumbles, stewed rhubarb and added to saskatoons for a fantastic jam.
