Soil pH for Blueberry Plantings
Blueberries require a lower pH than many other fruit and vegetable crops. Before planting blueberries, test the soil to determine the pH level, as well as amounts of nitrogen, phosphorus, potassium and organic matter present. More information can be found …
Fertigation
Fertilizer may be applied in liquid form through the irrigation system rather than surface applying dry granular material. This process is known as “fertigation.”
There are some advantages to fertigation, including:
- Fertilizer is more efficiently used.
- Fertilizer may be applied
