If there is anything that you have to be able to do in giant pumpkin growing is be able to change your plans. Growers will spend a good part of the winter planning out what crosses they want to make only to not have a male flower available the day the female flower is to open.
Today I had to make my change in plans. I had my vine on the 335 Scherber placed perfectly for the 2nd pumpkin pollination but it wasn't meant to be. That second pollination hasn't aborted yet, but I've seen very little growth on it in the last two days. The first pollination seems to be sucking everything out of the plant so the second pollination isn't going to make it. I could cut off the first pumpkin, but there isn't any guarantee that the 2nd pollination will make it so I'm probably going to go with the first.
Today I started trying to position the first pollination better on the vine and get some of the side vines out of the way. I'm going to have some trouble later in the year with this pumpkin but you have to take what you can get sometimes.
This evening I gave all of the plant a foliar application of multi-mineral.
