Weeds and invasive plants, in a small amount of time, can take over any backyard.  This client, bought a small container of bamboo, that within a few seasons dominated the landscape. 

We removed all of the invasive species and weeds, set down a slate patio, and built raised planter beds on the perimeter of the garden.  Also, we inserted a planting divider to give comfortable space to the upper and lower tenants.
