Pros

  • Promotes quick growth in plants.
  • Especially beneficial for rhododendrons.
  • Strong reputation as a reliable and effective fertilizer.

Cons

  • Can produce a very strong and stinky odor.

Bottom Line

The Espoma HT36 Holly-Tone Plant Food is highly effective for promoting growth in acid-loving plants, especially rhododendrons. However, it has a strong odor and requires careful application to avoid overgrowth and potential harm to pets. Users with hydrangeas or sensitive pets should use it cautiously to avoid adverse effects.
