What should be done with laterals on the main stalk? Will I leave them on to allow additional corn to grow on them or does leaving them on the main stalk deprive the main stalk from food?

How do tell corn is ready to pick
10 Jan 13, Chris (Australia - cool/mountain climate)
It's usually ready when the tassles/threads are drying up or black/brown. You can peel back the leaves around the top of the cob before picking to check if it is ripe and fold them back to keep growing if it isn't ready.

how many cobs of corn can you expect to harvest from each plant
10 Jan 13, Chris (Australia - cool/mountain climate)
It depends on the variety. Most seem to produce two or three, but I've seen some varieties with four or five.

once the corn has been picked do you cut off the stalks and it regrows or do you pill it out and plant again

Corn doesn't regrow. I cut it off low leaving the roots to rot, and plant some beans around the stumps to boost the soil fertility.

Our corn has looked lovely but now something funny is going on some of the corn have lost the silk tops and the leaf around the cob has split open and come dwn a little showing some of the corn. also right on the top of the plants the tassles I gather a small cob has formed on a couple?? any ideas whats going on this doesnt sound normal.
