The McAllen Foreign-Trade Zone (FTZ) is located south of McAllen between McAllen and Reynosa. Commissioned in 1973, it was the first inland foreign trade zone in the United States and continuously ranks among the most active FTZs in the nation.
Marigolds take around 45 to 50 days to flower after you plant seeds, so seeds sown in early April should flower by May.
Marigolds flower better and look more attractive if you cut off the dead flowers continually from the time the begin to bloom until they stop flowering in fall. Cut back the dead flower heads as the blooms fade, removing them above the topmost set of leaves on the stem.
