Do You Still Need to Fertilize When Using Pon?

Absolutely, fertilization is still crucial when using Pon, despite its unique properties and any fertilizers it might contain. Here’s a detailed look at how to manage fertilization with Pon:

Fertilization with Pon:

**1. Lechuza Pon:

• Initial Period: Lechuza Pon includes a slow-release fertilizer. When you first switch to Pon, you should skip additional fertilization for about 3 months. This allows the initial fertilizer to work and reduces the risk of over-fertilization.
• Long-Term Fertilization: After this period, start using the ‘weakly weekly’ method—diluting your fertilizer and applying a small amount with every watering. This helps prevent the build-up of salts and avoids over-fertilization.
• Winter Consideration: If you switch to Pon during winter or in cooler conditions, the slow-release fertilizer will break down more slowly. Therefore, skip additional fertilization for at least 6 months before resuming your usual routine.

**2. Fertilizer-Free Pon (e.g., Bio Pon):

• Regular Fertilization: With fertilizer-free Pon, you should follow your standard fertilization schedule. Bio Pon doesn’t contain any added nutrients, so regular feeding is essential to ensure your plants get all necessary minerals.

Choosing the Right Fertilizer for Pon:

**1. Hydroponic Fertilizer:

• Ideal Choice: Pon is a soil-free medium, so it benefits from hydroponic fertilizers that provide all essential nutrients. Look for a complete hydroponic fertilizer that contains all 12 essential minerals.
• Avoid High-Salt Ingredients: High-salt fertilizers can cause burn and damage to plants. Choose fertilizers free of sodium, chlorides, and urea. Sensitive plants might also need fertilizers without nickel or cobalt.

**2. Complete Nutrient Solutions:

• Essential Minerals: Ensure the fertilizer you choose covers all necessary minerals since Pon lacks the natural minerals found in soil. This ensures balanced growth and avoids deficiencies.

Mixing Pon with Potting Mix:

**1. 25% Pon Method:

• Usage: Add Pon to the bottom of the pot (about 25%) to improve drainage, especially in containers without drainage holes. Top it with your regular potting mix.

**2. 50% Pon Method:

• Usage: Use Pon for the bottom quarter or edge of the pot and a top layer to help with pest control, such as fungus gnats. This method balances drainage and pest management.

**3. 100% Pon Method:

• Usage: Repot entirely in Pon for maximum drainage and pest resistance. This method is also beneficial for avoiding irritants, like fungus spores, which can be problematic for allergy sufferers.

**4. Mixing with Soil:

• Application: Mix Pon into your potting soil to enhance its drainage and aeration. The ratio can vary based on the needs of your plants and the type of soil.

Where to Buy Pon:

• Lechuza Pon: Available on Amazon and locally from specialty plant stores.
• Bio Pon: Accessible in New Zealand through local retailers or online sources.

Tips:

• Monitor Plant Health: Regularly check your plants for signs of nutrient deficiencies or excesses. Adjust your fertilization routine accordingly.
• Watering Needs: Pon retains water differently than traditional soil. Ensure you adjust your watering schedule to match the specific needs of your plants in Pon.

By understanding and adjusting your fertilization strategy when using Pon, you can optimize plant health and growth while enjoying the benefits of this versatile substrate.
