           of 8 M requires trees no higher than 4 M and sides no more than 3 M from the trunk to allow
           passage of equipment and penetration of light to the lower canopy.

                The advantages of annual tip pruning is that it provides reliable synchronized flowering

           in selected rows year after year in trees that remain the same size for many years. Although

           tip pruning is labor intensive, mechanical pruners are available that make the job easier and

           rapid so that many orchards can be pruned in a short period of time.  Shape pruning and the

           subsequent tip prunings are more labor intensive than annual tip pruning but only need to

           be done once to bring the trees into production while controlling the size of the new cano-

           py.  The economics of pruning need to be evaluated in detail, but growers who are utilizing

           these strategies are realizing good economic returns due to increased and dependable yields
           (Maximo Jerez, Mango Cluster, Dominican Republic, personal communication). Small acreage

           growers can afford hand pruning using machetes and small power tools along with ladders or

           mobile equipment to reach the tops of the canopy. For larger operations, mechanical pruners

           attached to a tractor are more cost effective than hand tools (Jose Vera, Venezuelan grower,

           personal communication). Regardless of the cost, annual tip pruning is more cost effective than

           letting an orchard outgrow its productivity.
