Support Blooming & Roots at a Great Price

About this item

Jack's Classic 10-30-20 Blossom Booster is a water-soluble fertilizer designed for vigorous flowering and root development. Blended with micronutrients, it ensures optimal plant nutrition for lush foliage and abundant blooms. The gradual nutrient release supports up to 4 months of growth, making it ideal for flowering plants in gardens or containers.

Application is simple: mix the measured powder with water, spray directly onto leaves or roots, or use in a continuous feed system. The included measuring spoon guarantees accurate dosing, preventing overfeeding or burning. Its safety features and micronutrient blend reduce the need for additional feeding, ensuring healthy, vibrant plants.

Imported from the USA and delivered via ExpressBox, this fertilizer offers reliable, high-quality nutrition for Indian gardeners seeking premium plant care. All duties are included, and delivery arrives in 11-13 days.

Key Features

  • 10-30-20 Analysis - Great for producing brighter, more plentiful flowers in flowering plants.
  • Many Ways to Feed - Blossom Booster can be used as a foliar or root feeding product. Great for spraying directly onto leaves, roots, or when used in a continuous feed system.
  • Water-Soluble Powder – Powdered concentrates go further than liquid fertilizers. Simply mix your measured powder with water and you are ready to feed with multiple gallons of liquid fertilizer!
  • Included Measuring Spoon – All Jack’s Classic fertilizers come with a convenient spoon to create the right amount of liquid fertilizer for your plants.
  • Micronutrients - Added micronutrients supply your plant with the nutrition it needs for optimal growth and health. Unlike other fertilizers, additional feeding is not required.
