To apply your deep root fertilizer, simply dig a hole twice the depth of the root system of your trees, then place your hand in the hole and apply the fertilizer in a slow, even motion. Make sure that the fertilizer is applied in a thin layer, as the heavier the layer, the more effective it will be. Be careful, however, not to apply too much fertilizer at once, as this can cause damage to your roots. If your tree has not yet started to grow, you can apply a layer of the fertilizer directly on the soil, making sure to loosen up the soil before applying another. A third layer of fertilizer can be added just before the first freeze, if you wish.
There are several benefits to deep root fertilization. The first is that it will help your tree tremendously in its quest to become established. Healthy roots will provide your tree with essential nutrients that will allow it to absorb more water from the environment and therefore stay stronger and healthier longer. Another benefit is that it is a non-selective type of natural fertilizer, meaning that it will provide all of the nutrients necessary for your tree to grow strong and healthy.
