Key Specs

Product:** 3rd Generation Osmocote Slow-Release Granular Fertilizer

Formula:** 318S

Weight:** 250g

Primary Nutrients:** Nitrogen, Phosphorus, Potassium (NPK)

How to Use

1. **As a Top Dressing:** This is the most common method for established plants. Sprinkle the granules evenly onto the soil surface. For a 1-gallon pot, use approximately 5 grams. For a 2-gallon pot, use about 10 grams. Lightly mix the granules into the top layer of soil.

2. **Mixed with Soil:** When potting or repotting, mix the fertilizer directly into your potting medium to act as a base feed. This ensures nutrients are available right at the root zone from the start.

Care & Safety

Store the fertilizer in a cool, dry place away from direct sunlight. Exposure to high heat can cause the granules to crack and lose their effectiveness.

Be aware that higher temperatures and increased soil moisture will accelerate the nutrient release rate.

If using in combination with other fertilizers, especially during the summer, reduce the application amount to avoid over-feeding.

Notes
