A friend of mine was wondering if you could grow English walnut trees in our area, Dallas Texas.

Yes They need a well drained soil, preferably a loam.
Carpathian (English) walnuts are climatically adapted to essentially all parts of Texas but they are largely unproven in your area.

The acid and neutral-pH soils of East and North Texas are suitable for carpathian walnuts, but common rootstocks used for carpathians do poorly in the extremely alkaline soils of South, Central and West Texas. Carpathians thrive in western portions of Texas if they are grafted onto the native Central and West black walnuts Juglans microcarpa (Texas black walnut) or Juglans major (Arizona black walnut). Very few nurseries propagate these native black walnuts as rootstocks, so this is usually a "do-it-yourself" project.

Thanks for the question!
