Choosing a tree


The choice of tree should be based on its size, form and other characteristics, such as growth rate, leaves, color and other aspects detailed in the abbreviated specifications listed adjacent to the tree's photo.  Please choose a tree that is appropriate for the site and will not grow so fast or get so large that it interferes with overhead lines.



Trees should be planted in a hole at least twice as wide and one and a half times as deep as the root ball of the 15-gallon container. Good quality planting soil and/or soil amendment should be mixed 50/50 with the native soil when back-filling.  The base of the tree trunk should not be below the surrounding soil level.  


The tree should be supported with two or three stakes to avoid wind damage.  Two support poles will be provided for each tree.  A direction sheet will come with the poles.


Pruning and Care


Most of the trees listed need very little pruning or care.  Some, however, may need pruning of the lower or interfering branches to help shape the tree in the early stages of growth.  Crossing branches also may need to be removed occasionally.


Sources of Other Information


Additional information on planting and care of trees can be obtained from Sunset's Western Garden Book; local nurseries, such as Sloat or West End; and various websites (e.g. Friends of the Urban Forest at www.fuf.net/resources-references).



Trees should be watered deeply once a week during the dry season to prevent the tree roots from thrusting

under and lifting the sidewalk.
