Fertilizer for Persimmon: NPK Guide and Application Rates
Persimmon trees are relatively low-maintenance fruit trees that respond well to moderate fertilization. The University of California Extension notes that both Asian (Fuyu, Hachiya) and American persimmon varieties have similar nutritional requirements, with Asian types typically needing slightly more potassium for optimal fruit quality. Persimmons are adaptable to various soil types and rarely suffer from severe nutrient deficiencies when grown in reasonably fertile garden soil.
Quick Reference
What NPK Ratio is Best for Persimmon?
The recommended NPK ratio for persimmon is 10-10-10. A balanced 10-10-10 feeds all three macronutrients equally, which works well when soil tests show no single deficiency.
Persimmon NPK needs shift at each growth stage. Balanced formula for young tree establishment during the Seedling phase, then phosphorus supports bloom and fruit retention once flowering begins.
NPK by Growth Stage for Persimmon
| Growth Stage | NPK Ratio | Notes |
|---|---|---|
| Seedling | 10N 10P 10K N 10% Nitrogen: leaf and stem growth P 10% Phosphorus: roots and flowers K 10% Potassium: health and disease resistance Learn more about NPK | Balanced formula for young tree establishment |
| Vegetative | 10N 10P 10K N 10% Nitrogen: leaf and stem growth P 10% Phosphorus: roots and flowers K 10% Potassium: health and disease resistance Learn more about NPK | Moderate balanced feeding during active growth |
| Flowering | 5N 10P 10K N 5% Nitrogen: leaf and stem growth P 10% Phosphorus: roots and flowers K 10% Potassium: health and disease resistance Learn more about NPK | Phosphorus supports bloom and fruit retention |
| Fruiting | 5N 10P 10K N 5% Nitrogen: leaf and stem growth P 10% Phosphorus: roots and flowers K 10% Potassium: health and disease resistance Learn more about NPK | Potassium improves fruit color, sweetness, and firmness |

Common Fertilizing Mistakes with Persimmon
- Over-fertilizing young trees, which delays fruiting onset by promoting vegetative growth.
- Neglecting to thin fruit in heavy-set years, resulting in branch breakage and alternate bearing.
- Applying nitrogen too late in the season, causing delayed dormancy and cold damage.
- Ignoring the different ripening requirements of astringent vs non-astringent varieties.
Tips for Fertilizing Persimmon
- Apply fertilizer in late winter before bud break, broadcasting under the canopy drip line.
- Persimmons are moderate feeders that rarely need heavy fertilization in good garden soil.
- Supplement with potassium if fruit quality is declining; potassium drives color and sweetness.
- Mulch with compost to provide slow-release nutrients and maintain soil moisture.
