The ideal time of year to undertake major landscaping projects depends heavily on regional climate variations, but early autumn and early spring are generally regarded as the premier seasons. Fall is widely favored by professional landscapers for planting trees, shrubs, and cool-season turf grasses because soil temperatures remain warm while the cooler air minimizes plant stress, allowing root systems to establish deeply before the hard winter freeze. Conversely, spring works exceptionally well for planting summer annuals, installing hardscape features, setting up irrigation systems, and reviving lawns after winter dormancy, ensuring plants flourish as seasonal temperatures rise.
