2. Composting for Blueberries
Composting is one of the most essential parts of preparing the soil, especially for planting blueberries. Start off with general compost added to the soil a few weeks before intending to plant as described above – from there, you can measure the pH and adjust the composting needs accordingly.
For blueberries to grow happily, they need soil between 4.5 and 5.0 – lower or higher and you won’t have the optimal growth you’re looking for.
If you need to increase the acidity of the soil, simply mixing some used coffee grounds into the soil and then measuring the pH levels again can sometimes be enough. Powdered lime can also be mixed into soil to increase the acidity levels.
Store-bought fertilizer can also be used for composting, but should always be diluted according to the instructions on the packaging to avoid killing your plants. Also never place fertilizer too close to the roots: This burns the roots due to over-acidity, and it’s a sure plant killer for blueberries.
