We are planting a second southern Magnolia tree. Please let us know what and how to prepare the soil prior to planting. The p[revious tree died probably because of the overdose of ammonium sulfate.Thank you- DS

growing area. Deep, infrequent irrigation is preferable. Frequent, shallow sprinklings do more harm than good. To determine how far water has penetrated, poke a soil probe (any long metal rod or screwdriver) into the soil. It will move easily through moist soil, stopping abruptly where soil is dry. As trees mature, expand the watering zone somewhat beyond the tree?s canopy (or dripline), which is where roots are actively growing.
