Allow plenty of room for a crop of sweet corn. It’s a tall plant that needs to be grown in blocks at least a metre square so it can form plump cobs.
Blocks are the recommended planting pattern as sweet corn is wind pollinated and growing it in a block maximises the spread of pollen and increases pollination.
Well-pollinated flowers produce well-filled cobs but corn grown in pots or in a row won’t develop good cobs.
Though corn takes up lots of room, it doesn’t use the real estate straightaway so the space around young plants can be used to grow other plants such as quick crop of lettuce planted between the rows or around the block of corn.
Cornstalks can also be used to support climbing beans while sprawling warm-season plants such as pumpkins and zucchini can also be allowed to spread
