Fertilizing Black and English walnut trees: a step-by-step Guide
This section provides a step-by-step guide to applying fertilizer to walnut trees. Let’s figure out these steps:

Before applying any fertilizer, it is imperative to conduct a soil test, ensuring the precise choice of fertilizer and application rate. This information will help you select fertilizer and application rates for your walnut tree.
Choose the right fertilizer for walnut trees:
Both black and English walnut trees require a balanced fertilizer that contains Nitrogen (N), Phosphorus (P), and Potassium (K). A standard recommendation is a 10-10-10 or 14-14-14 granular fertilizer. However, you will need to determine the specific fertilizer and application rate based on your soil test results and the age of your tree.
Generally speaking, Nitrogen is the primary nutrient of fertilizers for walnut trees; the second place goes for phosphorus and then Potassium. Other nutrients include ammonium sulfate, Potassium sulfate.
The right time to fertilize the Walnut Sapling
The best time to fertilize walnut trees is in late spring and summer for the next applies, just before new growth begins. It allows the tree to utilize the nutrients during its active growth period.
Application method:
There are several methods for applying fertilizer to walnut trees, including broadcasting, banding, and fertigation. Broadcasting involves spreading the fertilizer uniformly and evenly around the tree’s drip line. At the same time, banding consists in placing the fertilizer in a narrow band on both sides of the tree. Fertigation is another method for applying fertilizer through an irrigation system. Choose the way that best suits your tree’s needs and available resources.

Fertilizing Tips for Newly Planted Walnut Trees:
- Initial Fertilization: For newly planted walnut trees, apply a small amount of fertilizer, approximately 1/4 to 1/2 pound of actual Nitrogen, in a circle around the tree, about 18 inches from the trunk.
- Gradual Increase: Gradually increase the amount of fertilizer and the distance from the trunk as the tree grows.
- Juvenile Tree Fertilization: Agriculturalists commonly administer 4 ounces (113 grams) of N-P-K 15-15-15 fertilizer for each silly tree, divided into two separate applications – one in late spring and another in the summer season.
- Watering after Fertilization: Watering the trees after applying soil fertilization is essential to help the nutrients reach the tree’s roots effectively.
- Fertigation Option: Fertigation, which involves incorporating water-soluble fertilizers into the irrigation system, can be a suitable alternative for fertilizing walnut trees.
Check the soil PH:
Given that the fertilizer is high in Nitrogen, you need to regularly check the soil pH and provide the soil with lime to counteract the acidity.
Fertilizing mature walnut trees:
For established walnut trees, apply fertilizer at 1 to 2 pounds of actual Nitrogen per inch of trunk diameter, measured at chest height. Adding manure to fertilizer can improve soil fertility, reduce erosion, and improve water retention. Based on this, many farmers include waste at 10 to 20 tons per hectare. Spread the fertilizer evenly around the tree’s drip line, avoiding direct contact with the trunk.
Monitor and adjust:
Continuously monitor the health and growth of your walnut tree and adapt your fertilization practices accordingly. Signs of nutrient deficiencies or imbalances may include yellowing leaves, poor development, or reduced nut production. If you notice these symptoms, consult a local extension agent or horticulturist for guidance on adjusting your fertilization practices.
