Fertilizer Dilution Calculator
Fertilizer Dilution Calculator
Properly diluting fertilizer is crucial for plant health. Too strong, and you risk burning your plants; too weak, and they won't get the nutrients they need.
This calculator helps you determine the correct amount of fertilizer to use based on your specific plant, pot size, and fertilizer type.

Tips for Best Results
- Always water your plants with plain water before applying fertilizer to prevent root burn.
- Reduce fertilizer frequency during fall and winter when most plants grow more slowly.
- When in doubt, it's better to under-fertilize than over-fertilize.
Understanding NPK Values
The NPK ratio represents the percentage of Nitrogen (N), Phosphorus (P), and Potassium (K) in your fertilizer. For example, a 10-10-10 fertilizer contains 10% nitrogen, 10% phosphorus, and 10% potassium.
Nitrogen (N)
Promotes leaf growth and lush, green foliage. Higher values are good for leafy plants.
Phosphorus (P)
Supports root development, flowering, and fruiting. Higher values benefit flowering plants.
Potassium (K)
Enhances overall plant health, disease resistance, and drought tolerance.
Common NPK Ratios for Different Plants
| Plant Type | Recommended NPK | Best For |
|---|---|---|
| Foliage Plants | Higher N: 3-1-2, 10-5-5 | Promoting lush leaf growth |
| Flowering Plants | Higher P: 5-10-5, 7-9-5 | Encouraging blooms |
| Succulents & Cacti | Balanced low: 2-2-2, 5-5-5 | Slow, steady growth |
| Vegetables & Herbs | Varies by stage: 10-10-10, 5-10-10 | Overall growth, then fruiting |
