Question
This is our first time planting sweet corn in our raised bed.  We followed the instructions on the seed packet.  We planted about 3 rows of corn 1 inch deep as the packet said.  Our corn is now about 3-5 feet tall and tasseling and we see a bit of silks here and there.  About half way up the stalk, the stalk brakes.  We have staked these back (the ones that don't brake off entirely) and are staking others that are leaning.  Also the stalks started out a nice dark green, but the color of the stalks is becoming pale green to yellow as well. What do you think is causing the braking and color change.  Thank you very much for any info you can give me.

Answer
I grow close to 200 stalks per year, and the only two things I have ever experienced causing the stalks to break is high wind and/or raccoons. I have also heard of deer brushing up against the stalks, but since I have a fence, that has never been a problem.

The reason for the light green color is a lack of nitrogen. Corn is a very heavy feeder. It is important to side dress the stalks with a granular fertilizer high in nitrogen. This should be done at the time of planting, again when the stalks reach knee high, and one more time when they begin to silk. Fertilizing at these times will also result in larger ears of corn with full tipping of the kernels.

I hope this answered your question. Please write again if I can ever provide assistance.
