Product at a Glance
| Feature | Details |
|---|---|
| Product Name | Osmocote 14-14-14 Slow-Release Fertilizer |
| Fertilizer Ratio | 14-14-14 N-P-K |
| Formula Type | Controlled-release, resin-coated granules |
| Release Longevity | Approximately 3–4 months at 70°F / 21°C average media temperature |
| Best For | Nurseries, greenhouses, foliage crops, containers, interiorscapes, and landscapes |
| Application Methods | Incorporation into growing media or surface/top-dress application |
| Micronutrients | Use with Micromax or another compatible micronutrient program when complete trace-element nutrition is needed |
Key Benefits
| Benefit | Why It Matters |
|---|---|
| Balanced Feeding | The equal 14-14-14 N-P-K ratio provides a dependable foundation for general plant nutrition. |
| Long-Lasting Performance | Feeds for up to 3–4 months under typical 70°F growing media conditions, reducing repeat applications. |
| Consistent Nutrient Release | Coated granules gradually release nutrients as moisture enters the prill, helping maintain a steady supply in the root zone. |
| Professional Versatility | Suitable for commercial greenhouse crops, nursery stock, foliage production, containers, interiorscapes, and outdoor landscapes. |
| Labor-Saving Fertility | Helps reduce the time spent mixing, measuring, and applying frequent liquid feeds. |
| Flexible Application | Can be blended into growing media before planting or applied as a top-dress for established containers. |
Nutrient Profile
| Nutrient | Guaranteed Analysis |
|---|---|
| Total Nitrogen | 14% |
| Available Phosphate | 14% |
| Soluble Potash | 14% |
| Elemental Phosphorus | 6.1% |
| Elemental Potassium | 11.6% |
The 14-14-14 analysis makes this fertilizer a practical choice when plants need even, all-purpose macronutrient support rather than a high-nitrogen or high-potassium specialty formula.
Release Longevity by Average Media Temperature
| Average Media Temperature | Expected Longevity |
|---|---|
| 60°F / 15°C | 4–5 months |
| 70°F / 21°C | 3–4 months |
| 80°F / 26°C | 2–3 months |
| 90°F / 32°C | 1–2 months |
Release speed increases as growing media temperatures rise, so fertilizer longevity may be shorter in warm greenhouse conditions or during hot outdoor production cycles.
Best Uses
| Growing Situation | Recommended Use |
|---|---|
| Greenhouse Production | Use as a dependable base feed for crops that benefit from steady nutrition. |
| Nursery Containers | Incorporate into media or apply as a surface dressing for controlled feeding. |
| Foliage Crops | Supports consistent leaf growth and color in interior and greenhouse foliage programs. |
| Hanging Baskets & Perennials | Can be top-dressed for extended feeding after establishment. |
| Container Gardens | Helps maintain nutrition in pots, planters, patio containers, and mixed plantings. |
| Interiorscapes | Provides long-term feeding for indoor ornamental plants with reduced maintenance. |
| Landscapes | Suitable for ornamental beds and planted areas where slow, steady feeding is preferred. |
How Osmocote 14-14-14 Works
Each granule is coated to control how nutrients move into the growing media. Moisture passes through the coating, dissolves the nutrient core, and gradually releases fertilizer into the root zone. This controlled-release process helps provide plants with a more even nutrient supply compared with fast-release fertilizers that can wash through the media quickly.
Application Guidance
| Application Type | General Direction |
|---|---|
| Media Incorporation | Blend evenly into the growing media before planting for uniform nutrient distribution. |
| Top-Dress Application | Spread evenly over the container surface and avoid piling granules directly against plant stems. |
| After Application | Irrigate after applying to begin the release process and help move nutrients into the root zone. |
| Micronutrient Support | Pair with Micromax or another suitable micronutrient program when crops require complete trace-element feeding. |
| Storage | Keep product in a clean, cool, dry location until use. |
Always match the application rate to crop type, container size, growing media, irrigation practices, and environmental conditions. For new crops or production changes, trial the product on a small batch before full-scale use.
