Landscaping in Corcoran.

Acreage inland, conventional new-construction lots in the eastern developments, with almost nothing in between. Open agricultural ground broken by the Rush Creek corridor, with heavy soil across much of the city.

Corcoran is one of the fastest-growing cities in the state — projected to more than triple in population — and the new-construction side of it has a landscaping situation that barely exists elsewhere on our list. These are not properties with failed landscaping; they are properties with none. Bare graded ground, a strip of builder sod if that, and no beds, no edges and no structure at all. Starting from nothing is genuinely easier than undoing thirty years of accumulated decisions, but it means the ground itself has to be built first.

New construction here means construction fill, and it is the worst ground we work on. Lots are graded, the original topsoil is stripped and sold, and the finished yard is a thin skin over compacted clay subsoil that has had heavy equipment driven across it for a year. Anything planted into that without correcting it fails on schedule, and the correction — breaking the compaction and bringing in real soil — is not optional in Corcoran, it is the job.

The older two-thirds of the city is acreage on former agricultural land, and it behaves entirely differently. Heavy worked soil, old drain tile that nobody has a map of, contoured low ground that was shaped to move water somewhere specific, and full sun and full wind exposure. A Corcoran estimate depends almost entirely on which of these two cities the property is in.

Brand-new subdivisions have no established trees, which means full sun across the whole property for most of the day and no shelter from wind at all. Beds dry out faster than a homeowner moving from an older suburb expects, new plantings need more water through their first two seasons, and material that would be fine under partial canopy elsewhere struggles here. Plant selection has to match a landscape that has not grown up yet.

On the newest streets the neighbouring lots are frequently still building, which affects access, timing and how long a finished job stays clean. It is worth sequencing work around what is happening next door rather than installing a finished landscape beside an active site — we will say so if we think waiting a season gets you a better result.

On the new-construction side, timing is dictated by the building schedule rather than the weather. Installing a finished landscape next to an active site usually means repairing it afterwards, and waiting a season frequently produces a better result for the same money. On the acreage side the season is long but the volumes are large, so both halves of this city need booking ahead for different reasons.

New subdivisions arrive with no established anything — no canopy, no structure, no soil worth the name. That is a rare chance to get the ground right before it is planted over, and it is far cheaper to do at that point than to correct in five years underneath a landscape that has already failed once.

The most common error on a new Corcoran lot is planting before fixing the ground. The yard looks finished the day the sod goes down, which makes soil work feel like an optional extra rather than the foundation of everything on top of it. It is far cheaper to correct compacted construction fill before a landscape goes in than to dig one out five years later.
