I started very late this season. Just today i managed to pot some sweetcorn seeds F1 incredible.
Will it be worth pursuing the sweetcorn dream this year? Or is it too late?

Who can possibly predict what sort of summer we're in for after the weather we've had this year so far? 

Yours would probably require an 'Indian summer' to finish the ripening, but you might as well go for it!

Incredible seed packet shows 

sow - March, April & May, harvest August & September... variety of fast growing, long sweet cobs with good tolerance of common rust which helps to keep plants healthy, particularly in wet summers

which seems to cover all eventualities - so they should be fine Prakesh
