I have had the same backyard design for 10 years and plants r too large for space in front of retaining wall. I would ideally like to put some citrus trees there but not sure if its a good idea once the trees would grow. I would choose dwarf sizes. The area is southwest facing. Also, the area by the sago palm gets more shade as it curves back right there. The grass in front newds to be replaced or not sure as it looks bad cuz of new puppy. Any ideas suggestion are very much appreciated! Annabell
