Hello all, new to this group. Apologies for rubbish message a few minutes
ago.....blaim 4 y.o. son.
Does anyone have any advice about growing sweetcorn? I'm thinking of trying
it in my greenhouse, but have no experience. How much space does it need?
How tall will it grow (can I control the height)? When? I'm in the south of
Scotland so there is a possability of frost for another 6 weeks say.
Any advice welcomed.

We sow the seed singly in 3.5" or 5" polypots in mid-April and grow the
plants on until after the last frost has (hopefully) passed - first week
in June here. Then they are planted outside in a block to aid
germination at about 60cm/2ft. spaces each way. They will grow to about
4-5ft./120-150cm. high depending on soil and weather. We restrict each
plant to 2 good cobs rather than letting several grow.

The cobs should be picked as soon as they are ripe - i.e. when the
sheath becomes papery and translucent, then either eaten immediately
after picking or put into the freezer for storage.
