TheGardenLady received this question from June.
Would potatoes like a pine needle mulch?
According to Clemson University Extension, pine needle mulch is good
for potatoes.  See here.
Tip: Pine needles and coffee grounds make great mulch for acid-loving
plants, such as rhododendrons, azaleas, blueberries, raspberries,
strawberries and potatoes.
Please let TheGardenLady know how you make out with pine needle mulch.
I use pine needle mulch in my strawberries to thwart slugs…now I get to eat my berries!
