My corn has done pretty well this year with very few insects bothering it. I haven't treated it with any pest control remedies but I have heard of dropping mineral oil on the silks to keep out earwigs. I like to grow corn every year and if it doesn't turn out too good for my dinner table, the chickens will always enjoy it. Corn needs to pollinate itself so I plant an entire 4x4 box full and it will fit a whopping 64 plants(4 per square).
Corn likes to be watered often and consistently. I never got my drip system in this box so I have been placing a soaker sprinkler in the center of it for 15 minutes every other day. I rarely use sprinklers in my gardens but I figure its okay as it never gets above the low branches and seems to wet the whole box down well.
I also found a video that teaches a great trick to getting to your corn without the mess of shucking it! I tried it and it works really well. http://www.youtube.com/watch?v=YnBF6bv4Oe4
Luckily, this variety of sweet corn that I planted has been very tasty and true to its name !
