What Soil pH Do Acid Loving Plants Need?

Acidic plants tend to need a soil pH of around 5.5. Some acid lovers may do well all the way down to a pH of 4.5. The lower pH of 4.5 to 5.5 allows the acid loving plants to better absorb the nutrients from the soil. Slightly acidic soil improves nutrient access!

Generally speaking, soil with a pH below 7 is considered acidic. It just may not be acidic enough for specific plants to thrive. You can check soil pH with a soil pH test kit or a soil pH meter.

What Happens If Soil Is Not Acidic Enough?

For soil that is too alkaline, plants may have a hard time absorbing nutrients. This ultimately may result in poor growth or less than optimal growth. Depending on the pH and a plant’s soil requirements, plants may develop a nutrient deficiency as well.

How Can I Increase Soil Acidity?

To best care for plants that like acidic soil, you can increase the soil acidity if it isn’t currently ideal. Learning how to increase soil acidity is relatively easy with a little research. Consider adding acidic plant fertilizer / soil acidifier, pine needles, or sphagnum peat (peat moss).

Soil acidifier lowers soil pH and works well for blueberries and turning hydrangeas blue. Compost that’s decomposed thoroughly can also help to increase soil acidity. Manures and nitrogen fertilizers may also help to create more acidic soil.

Some gardeners report that coffee grounds can improve plant growth in the garden. More specifically, they often say to add coffee grounds for plants that like acidic soil. Other blogs dispute this as a myth. I don’t believe there’s a 100% guarantee on any of this coffee grounds in the garden business, so your mileage may vary.
