Sulfur for Plants

Sulfur for Plants by TPS Plant Foods

Liquid sulfur fertilizer that supplies sulfur while gradually lowering soil pH. Supports acid-loving plants such as blueberries, azaleas, and hydrangeas with targeted, easy-to-apply nutrition.

Why it works:

  • 6.5% sulfur — supports protein production and rich green growth
  • Sea kelp (Ascophyllum nodosum) for natural growth compounds
  • Gentle liquid formula — mix it into your normal watering, no separate feeding routine
