Aspen Tree Fertilizer
Aspen Tree fertilizer that promotes strong roots and vibrant foliage. This liquid feed keeps young trees supplied at the pace they insist on.
Why it works:
- 3.6-3-5.1 NPK — gently potassium-forward — steady growth with the root and stem strength potassium provides
- 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
