Fertilizing trees might seem like a straightforward task, but choosing the right type of tree growth fertilizer can significantly impact the health and growth of your trees. Whether you’re a seasoned gardener or a novice tree enthusiast, understanding the specific nutritional needs of different tree species is crucial. At Lamb Family Tree Care LLC, we’re here to guide you through the process. In this blog post, we’ll delve into the essential aspects of selecting the right fertilizer for your trees, ensuring they thrive year-round.

Different trees have varying nutrient requirements. Here’s a breakdown of the primary nutrients essential for tree health:

• Nitrogen (N): Promotes leafy growth and overall vigor.
• Phosphorus (P): Supports root development and flowering.
• Potassium (K): Enhances disease resistance and drought tolerance.

Deciduous trees, such as maples, oaks, and birches, shed their leaves annually and have specific nutritional needs:

• Spring Application: Use a balanced fertilizer like 10-10-10 to promote early growth.
• Summer Application: Switch to a high-nitrogen fertilizer to support lush foliage.
• Fall Application: Use a low-nitrogen, high-phosphorus fertilizer to prepare for dormancy.

Evergreen trees, such as pines, spruces, and firs, maintain their foliage year-round. They require a different fertilization approach:

• Spring Application: Apply a slow-release fertilizer with a higher nitrogen content (e.g., 12-6-6) to support new growth.
• Summer Application: Use a balanced fertilizer to maintain steady growth.
• Fall Application: Opt for a low-nitrogen fertilizer to reduce the risk of winter damage.
  

Fruit trees, including apple, pear, and cherry trees, need specific nutrients to support fruit production:

• Early Spring: Apply a balanced fertilizer with micronutrients (e.g., 10-10-10 with added zinc and boron) to enhance fruit set.
• Post-Harvest: Use a high-phosphorus fertilizer to replenish nutrients and prepare for the next growing season.
  

Newly planted trees need extra care to establish strong roots:

• Initial Application: Use a root-stimulating fertilizer high in phosphorus (e.g., 5-10-5) at planting time.
• First Year: Apply a balanced, slow-release fertilizer mid-spring to support root and shoot growth.
  

Proper application ensures that your trees absorb nutrients efficiently:

• Measure the Tree's Diameter: Determine the amount of fertilizer based on the tree’s trunk diameter at breast height (DBH).
• Distribute Evenly: Spread the fertilizer evenly under the tree’s drip line.
• Water Thoroughly: Water the area well to help the fertilizer soak into the soil.
  

Avoid these pitfalls to ensure effective fertilization:

• Over-fertilizing: Excessive fertilizer can damage roots and create imbalances.
• Incorrect Timing: Applying fertilizer at the wrong time can reduce its effectiveness.
• Wrong Fertilizer Type: Using the wrong type of fertilizer can harm the tree or promote unwanted growth.
