Changing hydrangea flower color with coffee grounds is a popular garden hack that could do more harm than good.

'If you need to make your soil more acidic and lower the pH, you can try adding organic matter such as pine needles or ...

Soil pH or soil reaction is an indication of the acidity or alkalinity of soil and is measured in pH units. Soil pH is defined as the negative logarithm of the hydrogen ion concentration. The pH scale ...

The pH scale goes from 0 to 14 with pH 7 as the neutral point. As the amount of hydrogen ions in the soil increases the soil pH decreases thus becoming more acidic. From pH 7 to 0 the soil is ...

Hydrangeas are known for producing large blooms that fill up a space dramatically. Adding coffee grounds to the soil around ...

Blue hydrangeas thrive in soil with a pH range of 4.0-5.0, while artichokes prefer a pH range of 6.5-7.0. If your soil is too alkaline, you can add organic material such as a compost enriched with ...

Soil pH levels range from 0 to 14, with 7 being neutral. Levels below 7 are acidic, and those above are alkaline. Neutral soils are less common than either extreme and tend to cluster at the ...

The team's results show that extensive overuse has caused the pH of soil across China to drop by roughly 0.5, with some soils reaching a pH of 5.07 (nearly neutral soils of pH 6-7 are optimal for ...

Most plants thrive in soils with a slightly acidic to neutral pH of around 6.0 to 7.0. If you’re struggling with overly acidic soil, knowing how to raise pH in soil closer to that neutral range ...

Coffee grounds have a nearly neutral pH of 6.5- 6.8 (neutral is 7), but brewed coffee reportedly has a lower pH, ranging around 5.2 to 6.9 depending on the type of coffee and its strength.

Proper pH level of the soil is also key to supporting a wide range of beneficial microorganisms such as bacteria, fungi, protozoa and nematodes, which are present in healthy soil.

And looking at this one, my soil is pretty much neutral - pH 7. A test result between 6 and 7 is ideal because that means most nutrients are available for most of the plants we grow.
