||Fertilize an area three times the canopy spread of the tree 1 to 2 times a year with a 10-10-10 fertilizer. Only fertilize an established tree.
||Dig a hole three times the diameter of the root system, with a depth no deeper than the original soil line on trunk. Break up the soil to the finest consistency possible. Place plant in hole and fill, compacting the fill dirt. Water the plant heavily to seal soil around the roots and remove air pockets. Water well, and remember to water regularly until they have started to grow.
