Companion planting is like creating a garden buddy system where certain plants team up to support each other’s growth and well-being. It’s pretty neat how different plants can have such beneficial relationships with each other.Take tomatoes, for instance.

Plus, it adds a nice touch of diversity and charm to your garden!

So, when you plant tomatoes alongside their favorite companions, it’s like assembling a dream team for your garden.
