The corn should be planted directly into the tub because it does not transplant well. The corn plants will produce about three ears of corn per plant, or about 18 ears per harvest. A harvest usually occurs within 8 to 10 weeks of planting. That means that the average production of corn is about one ear of corn every four days in each tub.
Corn is an ancient South American plant which was engineered perhaps from a grass called teosinte.
The corn is planted about one inch below the surface, and usually germinates in about six days. The places where corn does not grow should be replanted to ensure six plants per tub. Corn is nitrogen hungry and usually kept on grow nutrient until after the top has tasseled and the silk has formed. When the corn tassels, the pollen has to fall from above onto the leaves below and into the fold of the leaf. If all the silk is pollinated the corn kernels should all form.
