Tips from the Pros

  • Use When Transplanting to Reduce Shock - Apply during transplanting to help reduce stress and transplant shock. This promotes faster root establishment and helps plants bounce back quicker, especially in vegetables, trees, shrubs, and houseplants.

  • Apply Weekly for Root Development and Recovery - Use a diluted solution once a week for plants that are recovering from stress (like pruning, overwatering, or environmental changes), or to encourage continuous root development in young or struggling plants. It’s especially helpful during the early stages of growth.

  • Great for Trees, Shrubs, and Houseplants - This formula isn’t just for house plants - it’s excellent for deep-rooted trees, ornamental shrubs, and fruits and vegetables. Use it to encourage stronger root systems and long-term plant health across your entire landscape or indoor garden.
