Fertilizer Program

Recommended Fertilizer

Dynamite All Purpose 18-6-8

Treeland recommends that customers apply Dynamite All Purpose 18-6-8 controlled release fertilizer which provides a steady and continuous supply of macronutrients and micronutrients for up to 9 months. When it comes to new landscape installations, an often overlooked element is plant nutrition. When trees receive the proper amount of nutrition they more easily adapt to their new surroundings making them less susceptible to disease, insects and other environmental stress factors. Optimal plant vigor can be achieved when all the essential elements are in ample and readily available forms which are divided into two groups: macronutrients (elements that are consumed in larger quantities) and micronutrients. Most fertilizers only supply the primary macronutrients Nitrogen (N), Phosphorus (P), and Potassium (K) and often overlook the six micronutrient elements Boron (B), Copper (Cu), Iron (Fe), Manganese (Mn), Molybdenum (Mo) and Zinc (Zn). These micronutrients play key roles in plant growth even though the required amount of any one of the micronutrients is a very small fraction compared to the macronutrients.

Where to Buy

Dynamite fertilizer can be purchased at Home Depot (Store SKU #887762).

How it Works

Dynamite Granules

Controlled release fertilizers like Dynamite All Purpose 18-6-8 provide the greatest degree of safety because each granule completely coats the macronutrients and micronutrients which ensure a consistent and predictable release. When Dynamite is applied to the soil, water enters the granule through the pores and dissolves the nutrients which are then steadily released through the same pores. The rate at which the nutrient solution is released is primarily controlled by temperature and that rate strongly correlates with trees metabolism. For example, when it is warm and trees are in active growth the coating expands allowing more nutrients to be released. As temperatures drop and trees go into dormancy in preparation for winter the coating contracts nearly ceasing the release of nutrients. This extremely consistent fertilizer release even during extreme conditions allows customers to apply Dynamite all year long.

How & When to Apply

Top-Dress by placing the fertilizer directly on top of the soil surface. Care should be taken to evenly distribute the granules around the entire root ball to encourage proper root development. Customers can immediately apply Dynamite on the trees once the trees are planted and any time of the year. Customers can reapply after 9 months from the initial application.
