We plant our trees and guarantee year-round with our 90" and 65" tree spades.  Our pod trailers allow us to plant multiple trees at a time, so large jobs are not a problem for us!  Our 90" spade digs a hole 90" wide by 60" deep.  Our 65" spade digs a hole 65" wide by 50" deep.  This allows for the maximum amount of undisturbed soil and roots to be planted.  The success rate on this type of planting is 98%, even in the hottest of summers.  We fully guarantee our work and will replace any of our trees for one full year after planting. ***( Guarantee is only valid with the purchase of irrigation ).
