About Corn

Corn is a warm weather crop and should not be planted until the soil warms up to 60° F. It is one of the taller home garden crops, so locate it where it will not shade out other crops. Corn is wind pollinated, and to ensure adequate pollination, sow seeds in several rows to form a square or on hills with several plants in a circle. Some sweet corns can be adversely affected by cross pollination from other corn varieties.

Nutrient, fertilizer, and repotting needs for Corn: repot after 2X growth

Most potting soils come with ample nutrients which plants use to produce new growth.

By the time your plant has depleted the nutrients in its soil it’s likely grown enough to need a larger pot anyway.

To replenish this plant's nutrients, repot your Corn after it doubles in size or once a year—whichever comes first.

I didn’t expect to see these growing when I was putting my plants that didn’t make it (plants-seeds——basically like a plant cemetery lol) last winter. I was shocked that they were growing healthy and happy. I’m still trying to figure out if these are ‘corn’ tho. Cuz there are so many plant / flower seeds that ended up there and corn seed is NOT common in my house. I personally think these might be sunflowers but I’ll love them no matter what.
