I had no problem keeping it wet. The spring water table was just a
couple inches below the surface. We kept a sump pump running until the
concrete was being poured into the hole. It was a good dry mix
relatively speaking, yet when the concrete reached the top, it was
pushing out water.
As I was breaking up the over flow a couple weeks later, someone asked,
"Wouldn't it be easier to just paint it green?" The dirt under the
hardened overflow was still soggy. So other than sprinkling the
surface, keeping it wet was not a problem<:-)

, no stress on the concrete for 6 weeks after the pour.
Even lowering the tower straight down, that is still a fair
load/stress for concrete not fully cured, or at least almost cured.
The last few % takes a long time.
They stressed that with concrete, let it cure properly and don't rush!

The % of cure asymptotically approaches its final value (gets closer
and closer at a slowing rate of approach) so that theoretically it
never quite finishes curing but gets close enough for most practical
purposes (90% of the final strength) in 28 days if the temps aren't
extreme (hot or cold.) Keeping the pour wet, especially the first
several days is a good tactic.
