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.
Bloom Time. Blooms appear for approximately one week in the late spring or early summer. Gardeners can extend the blooming season up to six weeks by selecting varieties that bloom early, midseason and late in the season. The large blossoms come in many colors except blue.
