They still seem fine, but does anyone here know if I should do something to protect the plants?

This is a very weak plant anyway. It can live, but not thrive.

Why the plant is this small this late into the season? Not sure if you can get decent harvest...

It's so small because the first time I put seeds into the garden soil, nothing happened. It was late May but still too cold and wet. I couldn't go and check if any seedlings/plants were growing at the time so I tried again once I'd figured nothing was growing. And it was already too late actually.

Honestly, this is one of the larger plants. They're not really growing much either. I'm afraid I'll have no pumpkins this year.

Sry not much hope. Better plan for next year. It is almost end of season.

Will cold temperatures easily kill the plants?

I think this was just a bad year for pumpkins, at least where I live. And of course, I'm a beginner. It's quite unfortunate because I waited for the pumpkin season all year and now nothing's happened.

Hey, I guess it may already be too late, but I thought I'd mention that a few weeks back I accidentally half-severed my vine while trying to stake the plant. I figured it was a death sentence but just to try something, I heaped dirt over the cut area, watered it, and pruned off a few leaves growing after the wound in order to conserve power. To my surprise not only did it survive but it's growing as fast as ever. I'm not sure if the wound healed under there, but I do see that it has grown roots into the extra dirt I put there and I'm sure that helped.

Even if it's a weak or slow plant and it might be too late to get a pumpkin by Halloween, you might as well keep it going. I'm in the same boat and I'll be happy for the experience of growing a pumpkin even if it takes me through November. This is how we learn for the next year. Good luck :)

Agree, I'm not giving up yet.

I just hope the cold doesn't kill the plants or stop the pumpkins from growing, if at all they even get flowers... Glad I saved most of last year's seeds.

Wow!! About those flowers I just mentioned... Noticed this just an hour ago:

Are these plants confused or what?!!

So what will happen, even if a female flower gets pollinated, will there be tiny fruits or will this not work at all?

It also seems my plants aren't growing anymore. The leaves are getting bigger and the vines thicker, but that's it.
