Hi dbatt. Welcome!
Which question are you talking about?
I've experienced my squash flowers falling off the vine before they get mature enough to open. It is hard to ask about that because it is so common for unpollinated ones to fall too.. most people's minds go there. This place has been an amazing help to me in getting down to the bottom of things so try to be patient while things get discussed.
For me, it used to happen because my squash plant just didn't have the reserves to make another squash at the time, so it killed off the female flower before allowing it to mature. Once I fertilized it and the weather got better and I fixed the irrigation system to better water it where it needed.. it was able to make a lot more female flowers mature and bloom.
