| We have a medium sized backyard garden and plant several rows of corn. We have experienced several years of corn smut. We have rotated our crops every year, however there is only so much you can do in the size garden that we have. Should we not plant corn for a year? Is it the soil that holds the smut? What can we do? We do so love growing corn. |
| Here's the good news about corn smut: it's a fungus that's highly regarded by some individuals and is actually served in some restaurants. Now, here's the bad news: corn smut is a fungus that can survive in the soil 5-7 years. While it is not within the seed, the fungus can survive on the seedcoat. The infection occurs most often when soil temperatures are between 68F and 86F degrees. Here's what you can do: If your soil is infected, don't plant corn, or at least rotate your crop so it's not in soil that's held infected corn for at least 4 years. Plant resistant cultivars like 'Goldie' and 'Blitz'. Plant the seed only 1-inch deep to promote rapid germination. Keep the seedbed moist for the first 4 weeks after planting. If you have the time and patience, pre-sprout your corn seed by placing them between damp papertowels and sealing in a plastic bag. Then carefully plant the spouts. Or, start your seeds in either one-quart or one-half gallon paper milk cartons. When the plants are 8-10 inches tall, cut away the bottom of the container and cut down the length of two sides of the container. Then dig a hole exactly the same size and depth as the container, and carefully transplant your seedlings. These extra steps will help the corn grow to maturity without developing smut. |
