THE FACTS

Pine needles themselves are acidic but they do not have the capacity to appreciably change the soil pH (make it more acidic).

  • Pine needles break down naturally and the microbes (decomposers) in the soil neutralize them.

Pine needles can be used to mulch shrub borders, flower beds and vegetable gardens
