Potato Fertilizer
Potato fertilizer for robust tuber production and healthy foliage. Feed the vines generously through the season and the hills fill with tubers.
Why it works:
- 3.6-3-5.1 NPK — potassium-forward to move sugars into the crop — heavier yields with even ripening
- All-nitrate nitrogen — the form roots absorb directly, for faster response and lower burn risk
- Calcium (2.1%) and magnesium (0.75%), plus iron, manganese, zinc, boron, and copper — the micronutrients that prevent pale leaves and stalled growth
- Sea kelp (Ascophyllum nodosum) for natural growth compounds
- Gentle liquid formula — mix it into your normal watering, no separate feeding routine
