They are reported to form nearly pure stands on abandoned farmlands, and attain their best development on coastal plains and along waterways.

Vochysia timbers are used for the same purposes as those produced by the genus Qualea, and the two genera are often referred to by the same vernacular name in some areas. Substitutes Spanish Cedar Comments Can be used for utility plywood, drawer bottoms, and panels, low resistance to decay General finishing qualities are rated as good Blunting Effect Little Slight effect Boring Fairly easy to very easy Satisfactory properties Carving Fair to Good Results Good results Easy to carve Cutting Resistance Easy to saw Easy to saw Cutting Resistance with green wood is easy Cutting Resistance with dry wood is easy Cutting resistance is variable Gluing Easy to glue Good properties Mortising Fair to Good Results Fairly Easy to Very Easy Good mortising properties Finishes well Moulding Fair to Good Results Fairly Easy to Very Easy Good moulding properties Nailing Holds nails well Easy to nail Planing Fair to Good Results Fairly Easy to Very Easy Planes to a poor finish Planing and other machining operations are easy. The timbers respond well to machine tools, although there may be some raised grain and woolly surfaces.
