Pouring concrete for trench fill foundation question.

I am laying a foundation for a garden wall and am mixing the concrete myself in a mixer. Do I have to fill the entire length of the foundation in one go whilst all the concrete is wet?

If not, should I fill the whole trench in layers or fill to the top of the trench in sections?

Hope that makes sense.

Thanks in advance.

Ideally in one go.

If not, then dig 1 section to full depth and put in a few lengths of rebar. I think this is usually done by digging one section of trench, square off the trench end square with a spade, bang some rebar into the soil and leave poking half out.
I'm no way a pro, but the minimum depth of strip Foundation is around 150mm so as long as you put in that much for each layer there couldn't really be a problem.
