landscaping (n.) Look up landscaping at Dictionary.com
"art of laying out grounds and arranging plants and trees for picturesque effect," by 1861, verbal noun from landscape (v.). Earlier in the same sense was landscape-gardening (1763).
The question, however, is, Can landscape-gardening (or short and sweet, landscaping) be taught? It, plainly, cannot. ["The Gardener's Monthly" July 1861]
Also, in reference to the visual arts, "depiction as a landscape" (1868).
