When planting your corn seeds there are a few things you can do to give your plants the best chance to pollinate. Pollination is important as it ensures your crop will produce delicious sweet corn cobs for you to eat.

How to plant your corn seeds

The most important thing you need to remember when planting your corn is…

Plant in a pattern

Arrange your seeds in a block pattern (as displayed in the image gallery on the right of this page) and space them 20cm apart. This will give your plants the best chance to pollinate.


Thoroughly water the soil so it is nice and damp.

Create a space

Make a small hole in the ground for each seed, following the pattern displayed. As a rule of thumb each hole should be around twice the depth of the seed, so approximately 1.5cm deep.

Plant your seeds

Place each seed in a prepared hole, lightly cover with soil and pat down gently.

Water... again

Once the soil has dried out give your plot a light water. Not too much, don’t flood the seeds or they will become waterlogged.

In the City Crop we’re planting heirloom sweet corn variety, True Gold. If you would like to do the same at home visit The Diggers Shop in Adelaide Botanic Garden for everything you need.

Next week we’ll give you some important tips for nurturing your crop as it grows.

Happy gardening!
