Sulphur

My plants are lacking Sulphur, how can I add this to the soil to get it to the plants?

Beleive it or not go to an Automotive store they have it for batteries buy sulphurc acid in liquid form. Understand it is a concentrate and if to much is used it will kill everything.

What makes you think that your plants need it? It is used more for a ph stabilizer (or down) not catation for plants because of the inherant dangers associated.

Gypsum would be your best bet.

Or, garden sulfur, or Sul-Po-Mag.

Garden centers or feed stores would be your best bet.
