(See UPDATE that follows) Our front yard was mostly dirt and tree roots. Hermanos Flores helped with landscape design, and completed installation of plants, planter boxes, and a drip irrigation system in a timely and professional manner. Extremely pleased with the final outcome (as are neighbors). The quality of the work was first rate.
UPDATE 10/18/19
At this point, sadly (and expensively), we are cautious to recommend Hermanos Flores Gardening. Installation was gorgeous. We promptly paid more $10,000 (after several more thousand to other companies, to clear out 5 mature birch trees lost to the drought). Our yard led to at least one other big job for Hermanos Flores Gardening in our neighborhood. They have similar problems, albeit fewer because their yard is shaded.
What we sadly discovered is that Alex has no concern for problems post-installation. Only after repeated complaints will he follow through. Our backyard was without water for a month, for example, until he finally took the time to find a large underground leak in the new irrigation system. Then front yard landscape plants started to die, irrigation problems (large and small) manifested, 4 foot weeds started snaking out from under the weed barrier fabric (and nutsedge sprouted right through -- I continued to heavily weed), and an organic walnut tree sapling was improperly removed so that there is now a healthy tree growing where it shouldn't be (the greenest plant in our photos, sadly).
Irrigation zones were mixed up, so that our planter boxes kept flooding, headed for dry rot, and the decomposed granite darkened with algae. Alex was called multiple times. When I finally discovered this as the problem, he ignored it. Instead, Alex proposed work at the cost of another $2,000 for "fixes" that were no longer needed (once I rectified the zones), AND the cost of replacement plants -- plants that, he admitted, were not suitable for the Davis heat or soil. Alex knew the plants that thrived in Sacramento. We trusted a landscaper to have this information, if not research it. (Space is limited; you can read more on Yelp.)
