Corn tasseling early

Asked July 21, 2014, 2:56 PM EDT

My corn is only 2-4 feet tall, no ears in sight, but tassels at the top are already out and falling off. What caused this? I planted them in three sisters barrels and in potting soil with compost, later fertilized with blood meal. Leaves looked green and healthy the whole time. All the other plants (beans, edamame, pickling cukes, and squashes I planted around them are doing great.

I would suspect you plant lacked pollination to form the ears. Corn is wind pollinated and should be planted in blocks rather than long, single rows or in individual pots. Here is a link to CSU Plantalk on sweet corn - http://www.ext.colostate.edu/ptlk/1816.html. Please let us know if you have additional questions.
