Just to add to what has been said here. The three sisters is not the only form of companion planting you can do. There are many. My favorite other examples also include: Strawberries planted next to blueberries and carrots planted next to lettuce. These may not provide as complete nutritional value as the three sisters but they are easy other options.

Good points, thanks. I will try carrot and lettuce.

Make sure they grow well in your hardiness zone! Just in case people aren't aware of them :-)

They actually do grow there, and people are aware, but thanks for the caution :)
