Corn is a long time favourite for gardeners and only one crop can be grown per season because of the time it takes to mature. The best tasting corn varieties are the bicolour and white varieties.

How Do I Grow Corn?

Directly sow presoaked seeds outdoors 1-2 inches deep.  Space your seeds about 2 inches apart then thin them out to 4 inches.  Water the soil and cover with chicken wire to keep birds out.  The seeds will sprout in 5-10 days, when the corn reaches 6 inches, remove the chicken wire. If you live in somewhere with a short growing season you'll need to either start your seeds indoors or sow in early summer as soon as the weather gets warmer. 

If you notice your corn browning, it is likely a nutrient deficiency. Try adding a boost of fertilizer. Corn also needs a consistent supply of water, and is a heavy drinker. They prefer to be in a self watering container. 

Make sure the soil temperature is dependably 65 F (18C) before planting your seeds.  Place a raccoon proof fence around your container when the ears are starting to form, especially if you live in an area that has raccoons.

Try buying transplants from your local nursery for a quick start! 

Companion Plants

Lettuce, beans, squash


¼ cup: Vitamin K (16%), Vitamin A (5%)


Harvest your corn when the silks turn brown, are dry, and the ear feels full.  The corn will be ready to harvest three weeks after silks appear.  You can push a thumbnail into a kernel to test if the corn is ready, if it is ready milky liquid should squirt out.  

When your corn is ready to harvest, hold the stalk firmly and snap the ear downward then up.  Use the corn as soon as you pick it as it can get starchy within hours.

Preparing and using

Eat your corn as soon as possible because up to 50% of its flavor is lost within the first twelve hours of storage.
