Marigolds won't bloom
I planted a packet of Burpee Snowball Hybrid Marigolds back in the Spring and they won't bloom. The buds get to the size of a pea and then just stop growing. As you can see from the picture, this is happening to all of the plants from that packet. I have other varieties of marigolds planted on each side of them and they have been profusely blooming. They get plenty of water and are fertilized around once a month. It's got me stumped. Anyone have an idea?
