Sulfate Of Potash

Sulfate Of Potash by TPS Plant Foods

Give plants targeted potassium support for root development and overall vigor without turning routine feeding into a complicated program. Sulfate of potash is useful when your regular fertilizer needs an extra potassium boost.

Use it alongside your normal feeding program as directed rather than as a complete stand-alone fertilizer.
