Monty J Is that one punkin on one vine? did you cut off all flowers to make it produce one Big pumpkin? I am learning to grow mine. I dont think they grow well in Hot desert sun ! Some day I hope to have a huge one !
Yes, that is one pumpkin on one vine. I usually hand pollinate 3 females. The first is at 8' out, the second around 10' and the third at about 12' out. When I say 8' out, I mean along the main vine. Pumpkin plants grow from a single main vine. From that vine, secondaries will be produced, and from those vines, tertiaries, and so on. To properly prune a pumpkin plant, remove all tertiaries. You only want the main vine and the secondaries. Anything else is salad that will take away from the fruit. As you can see in the first pic dated 6/30, the plant has the shape of a Christmas tree. That's what you're looking for early on. Eventually, the main and all secondaries are terminated by pi9nching off the growth tip as they reach the boundaries of the growing area. The finished plant will cover about 625 square feet.
After pollinating 3 females, I give each a week or so to determine which is going to be the best. There are a lot of considerations to take into account. Shape of the fruit, position on the vine, growth rate all play a part in deciding which one to keep. Once they hit basketball size, I choose which is the keeper and cull every other fruit and flower. That's the scary part. One fruit, one plant. If something happens to that fruit, it's over. Pull the plant and move on. It can be heartbreaking. Somewhere I have a picture of a fruit that went birdbath on me. It split out the blossom end at about 800 pounds. It was on course to hit over 1100 when it went down.
Jared, expect to spend 1-2 hours every day per plant for maintenance. You have to keep the tertiaries removed as well as all other flowers once you set a fruit. And just because you removed a tert, don't expect it to stay gone. The plant will often grow another in the same place, so you have to keep going back over the entire plant. Proper pruning is key to growing monsters.
Shading the fruit is a must. Like you, I usually used old bed sheets or blankets. Also, you want to bed the fruit on something once it sets. I always used play sand. The reason is because the fruit grow so fast, they need something to slide on. Otherwise, the bottom will bind on the soil and cause the divot in the bottom of the fruit, which could eventually split. At the peak of the growing season, it's nothing for a fruit to gain 30-50 pounds a day.
I don't remember the exact weight of the one JB is standing in. It looks like it probably went 500-600 pounds. I do remember that it had extremely thick walls. She was 6 at the time. The one in the truck weighed 1095 pounds and took 8th place at the 2005 Ohio Valley Giant Pumpkin Growers GPC World Weigh-Off in Canfield, Ohio. At the time it was weighed, it set a new WV state record. It was later beat by another pumpkin weighed in at Altoona, Pa by a 1105 pound fruit (grown in WV). I think it is now the third largest pumpkin ever grown in WV. I'm not sure though since I don't keep up with such things anymore.
Like I said, I'll stay out of the competition, and just watch. I would be happy to offer advice to anyone who asks for it though.
