Choosing the Best Fertiliser for African Violets

 

Selecting the right fertiliser for African Violets can significantly impact their health and blooming. Here’s a streamlined guide to help you choose the best fertiliser for your plants:

1. Ensure the Fertiliser is Complete

• Essential Nutrients: Look for a fertiliser that provides all 12 essential nutrients: Nitrogen (N), Phosphorus (P), Potassium (K), Calcium, Magnesium, Sulfur, Iron, Manganese, Boron, Zinc, Copper, and Molybdenum.
  • Calcium: Especially important for flowering plants. Ensure it’s included (typically listed around the 4th position on the label).
• Check for Completeness: Fertilisers that include additional micro-nutrients beyond NPK are preferable, as they meet all the plant’s needs.

2. Determine the Fertiliser Type

• Foliage vs. Flower Fertiliser: Choose based on the plant’s growth stage:
  • Foliage Fertiliser: Higher in Nitrogen, supports leaf growth. Ideal for young plants or those focusing on foliage.
  • Flower Fertiliser: Higher in Phosphorus, supports blooming. Ideal for mature plants or those ready to flower.
  • Balanced Fertiliser: Provides a mix, suitable if you want to support both foliage and flowers equally.

3. Additional Features

• Reduced Salt: Opt for reduced-salt fertilisers to avoid issues with root rot or fertiliser burn. Look for options without chlorides, sodium, or urea.
• pH Buffered: A pH-buffered fertiliser helps maintain the optimal pH range for African Violets, preventing nutrient lock-out or toxicity.

Application Tips

• Initial Growth: Start with a foliage fertiliser to promote leaf growth and plant maturity.
• Transition to Blooming: Shift to a flower fertiliser when your African Violet is ready to flower.
• Seasonal Changes: You can alternate between foliage and flower fertilisers depending on the plant’s stage and blooming cycle.

Summary

For healthy, blooming African Violets, choose a complete fertiliser with essential nutrients, including calcium. Opt for a formula suitable for your plant’s current stage—foliage or flowering—and consider additional features like reduced salt or pH buffering for optimal results. Popular brands like GT, Superthrive, and Plant Runner offer effective options tailored to various needs.
