Our Process


01

Soil Testing

We collect soil samples from the root zone and analyze them for nutrient levels, pH, and organic matter content.

Based on test results and species needs, we develop a custom fertilizer blend to address specific deficiencies.

03

Deep Root Application

Nutrients are injected directly into the root zone under pressure, ensuring they reach the feeder roots where they are needed most.

We monitor tree response and adjust the program as needed, typically recommending two to three applications per year.

FAQ

Frequently Asked Questions


When is the best time to fertilize trees?

Early spring and fall are the best times for most trees. Spring fertilization supports new growth, while fall applications help trees store nutrients for winter dormancy.

Is deep root fertilization better than surface application?

Yes, deep root fertilization delivers nutrients directly to the root zone, bypassing competing grass roots and reducing nutrient runoff.

Will fertilization help a stressed or declining tree?

Proper fertilization can help a stressed tree recover, but it is important to first diagnose the cause of decline. Over-fertilizing a severely stressed tree can actually cause more harm.
