3: Basil & Sage
As much as I love both these herbs and actually have tried pairing them together in my garden (it didn’t go so well), they both just have different requirements and thrive in substantially different conditions. Basil prefers moist soil, while sage shines in drier conditions, making them poor companions.
A better idea would be to grow basil near tomatoes and sage near rosemary or lavender instead.
4: Fennel & Almost Everything

Yeah…fennel is just one of those herbs I guess…
Trust me, I thought I could find an exception to this rule, some herb, bush, or vegetable plant that would thrive in the company of fennel. But, unfortunately, fennel is just like that one kid at school who nobody wants to play with. It releases certain chemicals that stunt the growth of most nearby plants, including other herbs.
Grow fennel in a completely separate pot or at least away from other herbs if you want to.

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.
