How Deep Should Corn Seeds Be Planted?

By Amy Deemer ; Updated September 21, 2017
Corn seeds have a variety of planting depths.

The ideal depth for planting corn seeds in average soil conditions is 1 1/2 to 2 inches. Plant seeds 2 to 3 inches deep in sandy or dry soil conditions. Seeds planted shallower than 1 1/2 inches may be eaten by birds or rodents and fail to root properly.
