NPK (5-15-45) Fertilizer

NPK 5-15-45 is a water-soluble fertilizer designed to support plants during the flowering and fruiting stage. It provides low nitrogen, moderate phosphorus, and high potassium — a combination that helps plants set more flowers, hold fruit better, and grow with less stress.

This formula is ideal once your plants are mature and beginning to flower or produce fruit. It works well for tomatoes, peppers, cucumbers, okra, and also for roses, hibiscus, fruit trees, and more.

Best For:

• Fruiting vegetables and vines
• Flowering plants (indoor or outdoor)
• Container-grown fruits like lemons, strawberries
• Mature plants entering bloom stage
• Summer flowering or fruiting periods

Benefits:

• More Flowers and Fruit: High potassium helps set more blooms and boost fruit size
• Strong Roots: Phosphorus supports deeper root development and nutrient uptake
• Low Nitrogen: Prevents excessive leafy growth during flowering
• Stress Support: Helps plants recover from heat, drought, or transplant shock
• Water-Soluble: Quick results and easy application

How to Use NPK 5-15-45 Fertilizer

For Potted Plants (8–12 inch pots):

• Mix 1 teaspoon in 1 liter of water
• Pour around the base of each plant
• Apply once every 10–15 days while flowering/fruiting continues

For Garden Beds or Grow Bags:

💡 Use this formula when flowers begin to form, or when fruiting starts. It's best not to apply during the seedling or leafy growth phase.
