Decorative Rock in Golden Valley.

Larger and more irregular than the grid cities to the north, with mature trees and genuine grade on many properties. Rolling and wooded, cut through by Bassett Creek and studded with small lakes — Sweeney, Twin, and the Hidden Lakes chain.

Theodore Wirth Park runs along the eastern edge of the city and the wooded character extends well into the neighbourhoods beside it. Those properties carry mature canopy, deep shade for most of the day, and the leaf volume that comes with it. Turf under that canopy is a losing battle on most lots, and the properties that look best here are the ones that stopped fighting it and planted for the shade instead.

The estate properties in the wooded pockets carry decades of accumulated planting, often laid out by someone who knew what they were doing when it went in. Clearing indiscriminately on those lots destroys value — mature specimen material is worth more than anything that would replace it. The work that pays here is careful: restoring lines, removing what has failed, and leaving what took forty years to establish alone.

Scheduling in Golden Valley depends heavily on which part of it a property is in. Wooded slopes near Theodore Wirth hold moisture and work up late; flat lots off Winnetka dry weeks earlier. A single city-wide start date is meaningless here, which is one more reason the estimate is done on the property.

The recurring error in Golden Valley is applying one plan to a property with several different conditions on it. A single lot here can have a sunny front, a wooded slope and a wet low corner, and treating those as one landscape produces work that succeeds in a third of the area. Zoning a property honestly and planting each zone for what it actually is works considerably better.

We work throughout Golden Valley, including Sweeney Lake, Meadowbrook, Glenwood and Hidden Lakes, and around Winnetka Avenue and Highway 55. Two properties on the same street can still need different work — which is exactly why the estimate is free and done in person rather than quoted off a photograph.

On a post-war lot decorative rock is usually a question of what comes out first. Seventy years of accumulated landscaping sits on these properties, the original plantings are long past their intended size, and clearing before installing is most of the work.

• Long-lasting finish
• Lower routine upkeep
• Defined bed lines
• Many color and size options

Rock installed badly is far more expensive to fix than mulch installed badly, because getting it out is a removal job. The classic failure is stone laid straight onto soft ground with no edge and no base: within a few seasons it has pressed down into the soil, grass has grown up through it, and half of it is in the lawn where the mower finds it. The second failure is fabric. Everyone expects fabric to stop weeds forever; what actually happens is that dust and leaf litter build a thin soil layer on top of it, weeds root happily in that, and now they are growing through a sheet that has to be torn out.

Rock is sold by weight and it is heavy, so both the material and the labour to move it scale quickly with area. Depth of excavation, the length of edge to be set, and whether existing material has to be hauled away are usually the three numbers that move the estimate most.
