Q: Do desert-adapted shrubs like Texas rangers, cassias and others benefit from adding sulfur to the soil? Will they perform better in a pH around 7.5 as opposed to 8? I know it’s probably not necessary but I’m just wondering if the additional sulfur in the soil will help them thrive better or if it’s overkill.
