Summer is fading into fall so it's time for mums, football and of course pumpkins! I've made hypertufa-concrete orbs in the past and thought pumpkins would be a fun little project as well ~ cheap plastic treat pumpkins make great molds!

I covered the hole in the bottom with a piece of duct tape, sprayed the inside of my pumpkins with cooking spray to keep the mixture from sticking and filled them to the top...I used rail road spikes for stems I pushed them right down the center, the mix was thick enough to hold them upright while they dried...

      I’m sorry they’re not setting up for you I’ve made a bunch more of these this year using the same “recipe” and have never had that issue. I have had some that have taken a little longer to set up because the mixture had more water in it but never as

    What colors did you use of the concrete color? I see Buff (which I bought on clearance last night!). Did you use another color for the brown-ish pumpkin?
