He focused primarily on the countryside of southern France, infusing his landscapes, always painted outdoors (en plein air), with light and color.

From 1886 he exhibited regularly at the Salons, each new season showing a marked advancement in his art, "bringing to the world of Paris new and delightful colour-schemes and vivid compositions.

Progressively he began to specialize in a style that would build his considerable reputation all the way to the United States, with many commissioned works both at home and abroad.

The importance he attaches to the tree is eloquent; representing for him the opacity of the earth in contrast to the unburdened transparency of the sky, with its silhouette projected onto the horizon.

"[7] He paints the twilight with passion, the waters that glide capriciously beneath the greenery, the flowering heather, the marvelous heather...for the pleasure of the eye [...] These fine droplets that illuminate spontaneous bursts of light in the works of Théodore Rousseau, or the delicate incandescent aura of Camille Corot, are revealed in Didier-Pouget.

[5]Didier-Pouget died in Digulleville, France, in 1959 and rests in the 5th division of the Cimetière de Montmartre in Paris, with his parents, wife and daughter.

By decree on 18 July 1933, Didier-Pouget was promoted to Officier of the Legion of Honour by the President of the France's Third Republic, Albert François Lebrun (1932 - 1940).
