I would like to plant trees on the west side of my home, primarily to shade/screen the afternoon sun.  
My home is about 14.5 ft from the wall and we have a sidewalk, 3 ft wide,  about 70 inches from the wall. 
Could you reccommend some trees to go between the wall and sidewalk to shade the house?  
From the front I have 66 feet to a newly planted Eucalyptus Citrodona(sp), 
what kind of spacing would I need for other trees?  
Thank you
