We get asked fairly often whether a landscape should be rejuvenated or rebuilt from scratch, usually by a facilities team taking over a campus or township with an existing but neglected landscape. The honest answer is that it depends on three things: the soil, the hardscape, and the mature planting.
If the soil is compacted or depleted but the layout and any mature trees are worth keeping, rejuvenation is almost always the better call — it's faster, cheaper, and preserves years of growth that a rebuild would throw away. This usually involves soil correction, selective replanting, lawn restoration and an irrigation check.
A full rebuild makes more sense when the layout itself doesn't work for how the space will be used now, when hardscape (paving, retaining walls, steps) has failed structurally, or when the existing planting is a poor fit for the site's actual light and drainage.
In practice, most campus and institutional projects we take on are somewhere in between — keep the trees, replace the lawn, fix the irrigation, and redesign one or two problem areas. A site visit is the only reliable way to tell which category a given landscape falls into.
