Corn: How to Grow and When to Plant in Your Backyard or Patio Garden!

Corn blog post
Although corn isn’t the most practical thing for us to grow, it’s still one of our favorites because it’s such a fun thing to have in the backyard. Plus you can’t match the taste of freshly grown corn! It is important to have at least a few rows of corn so that they can pollinate each other.

How to Grow:

Corn can be planted outdoors after the last spring frost and throughout the summer up until 14 weeks before your first fall frost. You can see specific dates for your location using our FREE iOS, Android, and Universal Web App.

Corn seeds are planted 1-2 inches deep, 4 per square foot, in full sun. Take care to notice what plants are around the area as well, see the companion plant section below. Corn typically sprouts within 5-10 days. Water weekly, more often in hot weather.

Companion Plants:

Companion planting is a vital part of organic gardening. Companion plants assist in the growth of others by attracting beneficial insects, repelling pests, or providing nutrients, shade, or support. There are also plants that do not like being next to each other. Some plants get too tall and can provide too much shade for your plant. Sometimes certain plants attract the same pests, so it is important to try and separate these.

Start checking daily once the ears feel full and the silky parts turn brown. You can test the corn before harvesting by pulling back the husk, piercing a kernel with your thumbnail and seeing if a milky substance comes out. Use one hand to hold the stalk while harvesting to prevent damage.

Cooking & Eating!

Use the corn the same day you harvest it for the best flavor. Refrigerate or freeze any unused corn. Freezing is recommended to retain the best flavor.

  1. I was surprised by how many small parcel of manually harvested corn there were in Oklahoma. I do not remember seeing large crops of it, but there were many small cornfields scattered about. There may have been large crops that were harvested and gone by the time we got there. The small parcels that I saw were still standing because they had been manually harvested. I do not know what it was for, but it must have been for small markets. It got my attention because corn is only grown here as a large irrigated crop. I did not investigate how it was grown in Oklahoma.
