Fertilizing Loquat Trees
Fertilize your loquat trees at the right time to support healthy growth and fruit production. Apply fertilizer in late winter or early spring before the tree starts its active growing season. This ensures that the tree receives the nutrients it needs for optimal development.

Choose the Right Fertilizer
Select a balanced, slow-release fertilizer with essential nutrients. Look for a fertilizer specifically formulated for fruit trees, with a balanced ratio of nitrogen (N), phosphorus (P), and potassium (K). A balanced N-P-K ratio, such as 10-10-10 or 14-14-14, is generally suitable for loquat trees.
Measure and Apply
Follow the recommended dosage on the fertilizer packaging. Measure the correct amount based on the age and size of the loquat tree. For young trees, use less fertilizer, gradually increasing as the tree matures. Apply the fertilizer evenly around the drip line—the outer edge of the tree’s canopy.
Mulch Application
After applying the fertilizer, add a layer of organic mulch around the base of the tree. Mulch helps retain soil moisture, suppresses weeds, and provides a slow release of nutrients as it breaks down. Maintain a gap between the mulch and the tree trunk to prevent rot.
Watering After Fertilization
Water the area thoroughly after applying fertilizer. This helps the nutrients penetrate the soil and reach the tree’s roots. Adequate watering is essential to activate the fertilizer and ensure its absorption by the roots.
Consider Micronutrients
In addition to the main nutrients (N-P-K), consider supplementing with micronutrients like iron, zinc, and manganese if deficiencies are observed. A soil test can help determine if micronutrient amendments are necessary for your specific planting site.
Monitor and Adjust
Regularly monitor the tree for signs of nutrient deficiency or excess. Adjust the fertilizer application in the following season based on the tree’s growth and overall health. Avoid over-fertilizing, as it can lead to imbalances and potential damage.
