How to grow Marigolds - Knowledgebase Question

I planted Marigolds from seed in early May. I was unable to plant them earlier because we experienced frost until May. They started to bloom a couple of months ago, but I have more green leaf than Marigold. They don't seem to be growing and I still have only a few blooms. Do you have any advice on how to grow Marigods? Maybe I will have better luck next year.

Marigolds need lots of sunshine in order to bloom well. If they get too much fertilizer, they will grow lots of foliage and not too many flowers. If you remove the spent flowers, your marigolds will bloom more because the plants are not using up energy to make seeds. Instead, they will redirect their energy into making more flowers. So, full sunshine, no fertilizer, water deeply when the top half-inch of soil is dry, and pinch off the faded flowers and your marigolds will be happy. Thrive in hot temperatures, so mid-summer is usually when they bloom the most. Best wishes with your marigolds!
