I tested the soil, and it's currently about a 7.0.

I bought some Espoma brand "Soil Acidifier". It's granular, Guranteed Analysis: 30% Sulfur; derived from Elemental Sulfur and Gypsum.

The bag says, "For Organic Gardening; Safer than Aluminum Sulfate."

It says you can use it around the base of the plant (I suppose they mean hydrangeas). Broadcast Rates are "12 lbs per 100 sq foot for each one point reduction in soil pH desired."

As I said, my moss garden is half planted. On the bare soil, I can broadcast this stuff.

My question (finally!) is this: will this stuff hurt the moss if I broadcast it directly onto the moss?

Anyone know?

Anyone wanna guess?

Thanks so much!
