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.
Determine where you will grow your marigolds. Marigolds grow well both in flowerbeds and in pots and other containers, but they need space to spread out. Fully grown marigold plants in beds should be spaced 2 to 3 feet apart so that they can get enough sunlight. Marigolds perform best in full sunlight, although they can handle up to 20% shade. Do not plant them in a fully shaded area, as they will not thrive.
