Earth Science Fast Acting Sulfur Granules – 5lb – Reduces Soil pH and Nutrient Runoff, Improves Growth & Color for Acid-Loving Plants, Long-Lasting Lawn Care Supplement

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.

Great for the garden and fruit trees!

This is perfect and has been helping keep my hydrangea soil in check to keep my flowers blue! Working well, would recommend and plan to purchase again when I run out

It works great. My first thought was it doesn't work, but then after a little time, it works just like it says. Be patient!

Lo estoy probando y la picazón le mi perro ha mejorado

Spreads easy with the spreader. Seems to be doing the job. But the ph was so high that it will likely take another round.

I’ve used this now for more than two weeks and indeed the pH does come down a little, but not in the amount that they make you think it’s going to. Moss is the quickest way to bring it down but even using moss with this you still don’t get it down far enough where fruit trees, vegetables and herbs like to be: 5.5 through 6.5 HP. It’d be great if this thing could do a better job faster to bring down the HP by making it more acidic without harming plants.

Just started using this to lower the soils pH.

Hydrangeas were turning pink now they want to turn blue

Tomatoes don't have bottom rot this year. Might be because of this product.

Je l’ai acheté pour avoir des hortensias bleus mais ils sont toujours roses. J’ai augmenté la dose en voyant les bourgeons roses mais ça n’a pas fonctionné. Je suis déçue de résultat sachant le prix payé.
