Success with growing Sweetcorn
2020 has been a very good year for sweetcorn. It is now mid September and we have been eating fresh sweetcorn regularly since the start of July and we should be eating fresh sweetcorn until at least mid October.

How to grow sweetcorn.
It is now possible to buy super sweet varieties of Sweetcorn seeds at any seed shop. I plant my seeds in a big flower pot or just any container which has soil at least 10cm deep. I put the seeds about 1cm down and about 5 centimeters apart.  I plant them out when the little plants are  about 12 cm high. Sweetcorn does not like the cold so it is best if the average temperature is over 14C when they are planted out. I doubt if they would survive a frost.

This year I made extra effort to fertilize them well using only organic fertilizer. Under each plant I have put a 3 double hand fulls of cow manure and one double handful of chicken manure. I prepared the ground using a small fork. Once they started growing well I put a thick mulch of leaves to suppress the weeds. Sweetcorn grows best in a group of plants rather than a line  so I have planted rectangular groups of about 20 plants.

To be able to harvest sweetcorn over a long periods of time I grow 3 or 4 patches. When one clump of sweetcorn gets well established I plant some more seeds. This year, eating sweetcorn every couple of days for months on end has been heavenly.

When to pick sweetcorn.
Each sweetcorn plant grows 2 or 3 corncobs.  People say that you should  open up a corncob and push your thumbnail into into a kernel. If you see a milky liquid it means they are ready. What happens if they are not ready? You have just ruined a corncob. The best indicator of being ready is when the beards go brown. Each corncob has a lot of strands coming out of the end they eventually turn brown. When almost all of the beard is brown they are ready.

How to cook sweetcorn.
The big problem with sweetcorn is that the fibrous kernels get stuck in your teeth. This problem gets worse as you get older because as you get older there are more gaps in between your teeth. This year we seem to have solved this problem. Either after cooking or before we cut the corncobs into bite sized pieces. The incisors at the front of your mouth cut the kernels of  the corncob without getting stuck in your teeth.

To cook sweetcorn put it in cold water, bring to the boil, simmer for between 10 and 15 minutes. Leave in a water for 5 minutes. We are at 1300 metres high here so water boils at 95C, your cooking time might be less. 

How to store sweetcorn.
If you don’t manage to eat all your sweetcorn fresh then you can leave it to go dry. Just pick the corncobs, take off the outer coverings and put them in a dry airy place. The best way to use dried corn kernels is to make sweetcorn fritters or maize fritters. There are loads of recipes on internet. The other way to store them is by canning/bottling them and the result is the same as canned sweetcorn that you buy in the supermarket. You will need a pressure cooker to get the temperature very high because sweetcorn does not have much natural acid. There are lots of instructional videos on internet.
