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.
How to Keep Marigolds From Getting Too Leggy When Growing Them From Seed. 1  Plant individual marigold seeds in their own peat pots or other small plant pots filled with potting soil. 2  Move the sprouted marigold seed pots into a bright, sunny window as soon as you see the green sprout emerging from the soil. Marigolds need at least 6 hours of bright sunlight each day, and more is better when it comes to growing a strong plant. Marigolds grown in plenty of bright sunlight tend to be thicker and bushier, while those grown with too much shade can be thin and spindly. 3 Turn each plant around every day to make sure that all sides of the plant get the same amount of sunlight.
