These are my tomatoes, they sprouted in late April and have not left the sprout stage in nearly 3 months. What do I do?

You can see a cluster of them to the bottom left and individuals spread around. We have them on raised beds near a maple tree in the yard because we were worried about the Kansas heat drying them faster then we could water. They get watered daily, they're not injured or weird looking, but they just aren't growing at all. What do we do?

Not pictured here is a Rosemary patch that's doing exactly the same, tiny little two leaf sprouts that refuse to grow further or die off.
