  • Lifesaver for my blueberries other acid loving plants
Size: 5 lbs.
Works fast and effectively - I’ve bought 2 bags of these now. This has allowed me to container grow blueberries, raspberries, blackberries, grapes, and so many other acid loving plants. And I verified the soil ph changed with soil testing kids! For the berries I put some in with fertilizer every 1-2 months to keep the soil acidic (it’s not an apply once and done). I like that they’re small pellets so you can adjust the ph level more finely. ... show more

  • Defective packaging
Size: 5 lbs.
Earth Science needs to look into the manufacturing of the product bags. Both side seams were busted open and product all over the inside of Amazon box. Otherwise, pleased with the 36% sulfur content. Good value.
