Are pine needles bad for vegetable garden?

Pine needles do not acidify garden soils. However, top dressing, or mulched materials break down so slowly that they hardly make a difference to a soil’s pH. The acidity of pine needle mulch remains at the soil’s surface and does not alter the soil around plants’ roots.

Pine straw is frequently thought to drastically increase soil acidity, making it bad for anything except acid-loving plants. According to research by the Washington State University Extension, pine needles do not make soils more acidic when used as mulch in gardens.

What soil do fir trees like?

For Douglas fir, blue spruce, and concolor fir the target soil pH is 6.5. Although these species may prefer, or can tolerate, somewhat lower soil pH levels, these target soil pH levels are recommended as starting points at initial planting time, since soil pH naturally decreases during the rotation.

Does Lowe’s sell pine needles?
