I'm not sure, it all depends on how many my brother ends up growing, we had too many last year as it was only me carving, I got help gutting them but I think around 6 went to waste, we just put them out in the garden anyway next to the giant garden spider we made. Last year was my first time carving like that, I maybe done one pumpkin before that and it was the usual pumpkin faces and I didn't know how long the pumpkins would last so I think I started around the 27th last year and kept them them in our summerhouse in the back garden where it was freezing, I just put vaseline inside and in all the parts that were carved which seemed to work well as I thought some of the designs would shrivel up but I also put cling film over the front too so I think that helped.
Good job for atleast getting three! I think they can be quite tough to grow as I know some of my brothers got infected and I think you have to spot it quick incase it spreads to the others, atleast now you've grown some you'll know more next year when you do it
