Cultural Notes:

• Sweet corn is frost tender so make sure that you sow seed after your last frost You will also have to wait until the soil warms up as seed will not germinate well below 15ºC. Tasmania needs earlier maturing varieties in order to receive a good crop, late maturing varieties will rarely receive enough heat units to be mature and sweet by the end of summer. Mid season varieties will provide a sufficient crop in a good summer. Plant 2 seeds together 4 cm deep and 30 cm apart from the next pair of seeds in rows 90 cm apart. Make sure that you plant at least 2 rows side by side to ensure better pollination and fuller ears of corn. The bigger the block of corn the better. Corn is a heavy feeder and needs plenty of water (space further apart if you wish to water less). If you have enough room plant a few varieties that mature at different times to spread your harvest over a longer period.
   

Problems:

• Earworms can be a problem. Some people use Dipel against these or put a few drops of mineral oil onto the silks to substantially reduce damage from earworms.
   

Harvest:

• Generally, the later the variety the sweeter the cob. We always peel back the ends of a few ears with dry and browning silks and squeeze some kernels, if they are full and ‘milky’ they are ready to eat.
