No peach blossoms this year...

I was hoping this was the year. I transplanted the tree in 2018. I actually began to fruit in the pot I bought it in from Walmart. But the fruit shriveled up and died while still tiny. Then I transplanted it and it's at least tripled its foliage since then. It gets plenty of sun and we get winter weather that puts it through the necessary cold period each year. I haven't fertilized it because it's very close to the chicken run and I figure it gets plenty of nutrients from the chicken run that gets washed down into the soil by rain. I haven't pruned it much so far either as I was letting it grow a bit before beginning to attempt to shape it.
I guess I just hold out hope for next year. I would like to be proactive with it this year if possible though. Anybody have ideas to get a peach tree to blossom and fruit?
