I created a stepping stone pathway made out of concrete. Some were poured directly into holes I dug in the ground, others were formed on top of the ground. I used powered concrete dye on the surface only. How should these cure? I've read conflicting information about whether or not to water them down because of the colored dye. It was a ton of work, and I really don't want them to crack. I would love some advice on the proper way to cure these.
