Deep Root Fertilizing & Airspade Services

The most important and crucial factor for your trees health begins below ground. Establishing a strong vigorous root system and proper soil depth are the key to happy and healthy trees. Our deep root fertilizer combined with a root collar excavation is the closest thing to a guarantee we can provide when it comes to improving overall tree health.

Deep Root Fertilizing

The quickest most affordable way to help your trees. Deep root fertilizing is the process of distributing a slow release fertilizer into the soil via water under pressure. Essential nutrients can then be easily accessible to your tree as required. The added benefit of the deep root watering contributes to opening channels beneath the ground to encourage future optimal root growth. When providing these essential nutrients to your depleted landscaped soils we are trying to recreate the conditions where trees are the healthiest. In the Forest! Not in a 10 ft x 10 ft front yard. Your trees will thank you.

Air Spade Services

The AIRSPADE is our favorite tool! Soil height and girdling roots are a major issue which has been going unrecognized and untreated for a long time. Now equipped with all the proper tools and know how we
