Here's some information on what crops to plant in Spring and Fall, as well as terrain information in Dallas.
March to May planting date. Plants are green, vigorous and growing in a vegetative stage until mid-late July to mid-August depending on rainfall frequency and triple digit afternoon temperatures. Plants move from a flowering into a fruiting or reproductive stage and will start maturing and turning straw to brown color for harvest about mid-August.
October 1 to Nov. 15 planting date. Plants are green, vigorous and growing in a vegetative stage until mid-late April to mid-May depending on rainfall frequency, sunlight, cloud-free days, insects, and afternoon temperatures. Plants move from a flowering into a fruiting or reproductive stage and will start maturing and turning straw to brown color for harvest about mid-June.
The Dallas Fort Worth area overlooks mostly prairie land with a few rolling hills dotted by man-made lakes cut by streams, creeks and rivers surrounded by forest land. DFW is situated in the Texas blackland prairies region, so named for its fertile black soil found especially in the rural areas of Collin, Dallas, Ellis, Hunt, Kaufman, and Rockwall counties.
Many areas of Denton, Johnson, Parker, Tarrant, and Wise counties are located in the Fort Worth Prairie region of North Texas, which has less fertile and more rocky soil than that of the Texas blackland prairie; most of the rural land on the Fort Worth Prairie is ranch land. A large onshore natural gas field, the Barnett Shale, lies underneath this area; Denton, Tarrant and Wise counties feature many natural gas wells. South of Dallas and Fort Worth is a line of rugged hills that goes north to south about 15 miles that looks similar to the Texas Hill Country 200 miles to the south.
