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.
Within one or two months, your vine should measure 6 to 10 feet and your first moonflowers should bloom. The first flowers will be small -- 3 to 5 inches across -- but eventually your moonflowers should measure up to 6 inches across. By late June or early July, the plant should be covered with blooms. Moonflowers may take five or six months to bloom after planting, which is why you should plant the seeds in late February or early March. Gather ripe seed pods after they turn brown, beginning in October.
