Marshalls Garden Concentrated Slow-Release Vegetable Feed Granules 850G - NPK 15-9-14

The feed is designed to release nutrients over a period of six months, providing sustained feeding for an entire growing season.

While formulated for vegetables, its balanced NPK and slow-release properties may benefit other garden plants. However, it's best used as directed for vegetables to ensure optimal results for those specific crops.

The ideal times are at the point of planting, by mixing it into the soil or compost, or around the base of existing plants as a top dressing, followed by watering.

This ratio represents the percentage by weight of Nitrogen (N) at 15%, Phosphorus (P) at 9%, and Potassium (K) at 14%. This specific formula is potassium-boosted to encourage stronger plant growth and yield.

Store the granules in a cool, dry place in their original, tightly sealed packaging to maintain their effectiveness and prevent premature activation.

Yes, the intelligent release system is activated by water and temperature. Nutrients are released more readily when conditions are warm and moist, and slower when it is cool and dry.

This product is a professional-grade chemical fertilizer. For strictly organic gardening, alternative certified organic fertilizers should be considered.

Ensure the feed was properly mixed with soil or compost and that adequate water is being provided. The slow-release mechanism requires moisture to activate. Re-application may be necessary if the soil volume is very large or conditions are extreme.

The release is activated by water and temperature. If the soil is very dry or temperatures are consistently low, the release may be slower than expected. Water the area thoroughly and monitor over a few days.

While this feed provides a long-term supply, some plants might benefit from a liquid feed supplement if severe deficiency is observed, especially during peak growth phases. Check for other environmental stressors like watering issues or pests.

If the packaging is compromised, moisture may have entered, potentially affecting the slow-release mechanism. Use a small amount for a test patch or consider contacting the retailer if significant clumping has occurred, indicating premature activation.
