Lawn repair and overgrown planting in Bridlewood

Bridlewood, and the Katimavik and Glen Cairn streets next to it, are where the original landscaping has reached the end of its natural life. Katimavik and Glen Cairn went up largely in the 1970s and early 1980s and Bridlewood through the later 1980s and 1990s, which puts the first generation of lawns, hedges and shrub beds somewhere between thirty and fifty years old. What comes up most often here is not a design question. It is a lawn thinned past the point where overseeding holds, a foundation bed that has outgrown its space by a metre, and a cedar hedge that needs decisions rather than a trim.

Compaction is the recurring soil problem. Three decades of foot traffic, children, dogs and the occasional parked trailer on clay-influenced ground produces soil that water cannot enter, and the symptom is a lawn that puddles in April and bakes hard in July. Core aeration in early September, followed by a 5 to 10 mm top-dressing of screened soil or compost and overseeding, is the treatment, and it usually needs repeating for two or three consecutive autumns before the lawn holds on its own. Replacing the sod without addressing the compaction underneath buys a single good season.

Lot sizes are modest and the houses sit close together, which changes the economics of everything. A rear yard reached only through a 900 mm side gate cannot take a machine, so soil, sod and paving stone come in by wheelbarrow and the labour portion of any quote climbs steeply. Before accepting a price for rear-yard work on these streets, confirm the contractor has actually looked at the access rather than quoting from a satellite image.

Two practical notes. Many of these driveways were widened at some point in the last three decades, and any change to the hard surface where it crosses the City road allowance needs a private approach permit under By-law 2003-447 (City of Ottawa). And the mature silver maples common through Katimavik have shallow aggressive roots that lift paving and invade weeping tile, so a bed rebuild near one of them starts with finding out where the roots actually are rather than with a rotary tiller.
