The seeding rate should be about 1 1/3 ounces of large-seeded varieties or 9/10 ounce of shrunken gene types per 100 feet of row. With large-seeded varieties, this will provide 155-235 seed and should provide 170-300 seed of the smaller-seeded varieties.
How many corn seeds are planted in each hole?
Planting – Sow seeds one inch deep in thick soils. The planting depth on light sandy soils may be 2 inches. Plant the seeds 8 to 12 inches apart in rows separated by 2.5 to 3 feet. Additionally, sweet corn can be cultivated in “hills.” Plant four to five seeds per hill, with approximately 3 inches between each seed. The distance between hills should be 2.5 feet, with 2.5 to 3 feet between rows.
Corn Spacing 101 – Garden Quickie Episode 8
Share our material, please! It is human instinct to be careful regarding the amount of seeds sown when establishing plants from seed. Naturally, gardeners like to sow exactly the same number of seeds as the desired number of plants. I have always held the same opinion.
I always wanted to conserve as many seeds as possible in order to save money on purchasing additional seeds for the next planting cycle or even the following season. However, yearly experience with seed starting has rapidly shown me that my assumptions were incorrect! How many seeds should thus be sown each hole, cell, or container? In general, two to three seeds per hole should be placed.
The germination rate of seeds is not 100 percent, thus not every seed that is sown will sprout. Overseeding holes, cells, or containers increases the likelihood that the desired number of plants will develop (or more!). You may not be convinced even after reading my proposal to plant more seeds than necessary.
