Fertilizer spikes feed trees at the roots, where they need it most.

For best results, apply in early spring when new grwoth begins. Water well before application. Using a hammer and the plastic driving cap, drive spikes one to two inches below the ground surface, evenly spacing the spikes in a circle approximately 10" to 12" from the main stem. Apply fresh spikes every 8 weeks or as needed during the growing season
