The Worst Herb Pairings: 7 Herbs You Should Never Grow Side By Side

Like basil and sage, rosemary and basil have immensely different watering and soil requirements. Rosemary loves dry, well-draining soil, while basil needs consistent moisture to be able to thrive. While the two can be extremely fragrant in the garden, they definitely shouldn’t be paired.
A better approach to pairing these herbs would be to grow rosemary with thyme and basil with parsley. These are much more harmonious combinations.
6: Chives & Beans
As strange as this pairing sounds to the ears, it’s actually not that uncommon. Many gardeners plan on growing chives and beans together but later wonder why their bean growth slowed down. It’s mainly because chives release compounds that slow the growth of beans.
A better alternative to this is to grow chives near something like tomatoes to help repel pests as well as contribute as a companion plant effectively.
7: Oregano & Marjoram
