Start the application of the fertilizer approximately 2-3 feet from the tree trunk and extend the same distance beyond the drip line. A grid pattern should be laid out, with a spacing of every 2-1/2 ft. to a depth of 4" to 8". A minimum of 5 gallons of tank mix should be applied per inch of tree diameter, with approximately 1/2 gallon of the fertilizer solution injected at each point.
