Ideal pH Ranges for Herbs

Soil pH Ranges for Herbs

Finding the right pH ranges for herbs can be the difference between growing pesto jars full of basil or a tablespoon or two of thyme.

Finding the Right pH Ranges for Your Herbs

While in general most herbs will grow in soil with pH ranges between 6.0 and 7.0, the actual pH values that individual herbs like best can vary quite a bit. So, if you’re not comfortable guessing what soil conditions your herbs prefer, use the table below to find the right pH value for your garden herbs.


pH Range

Basil 5.5 – 6.5
Chives 6.0 – 7.0
Cilantro/Coriander 6.0 – 6.7
Dill 5.5 – 6.7
Marjoram 6.0 – 8.0
Oregano 6.0 – 7.0
Parsley 5.0 – 7.0
Rosemary 6.5 – 7.0
Sage 6.0 – 6.7
Thyme 6.5 – 7.0

What is pH and Why Do pH Ranges Matter?

Soil pH is a measure of how acidic/alkaline a given sample of soil is. The pH scale runs from 1 (extremely acidic) to 14 (extremely alkaline) and a pH value of 7 signifies that the soil is neutral.

Knowing your soil’s pH is important because the pH of your soil can dramatically affect a plant’s ability to take in nutrients, which, in turn, can affect its ability to fight disease, handle stress, grow, and produce fruit. If your herbs aren’t growing the way they should be, it might be time to check your soil’s pH.
