At each leaf node on a pumpkin plant roots will grow out of the top and the bottom of the vine if you bury them. It is a lot of work burying vines but it pays big dividens at the end of the season. I had to remind myself today to cut those roots that are next to the pumpkin because as the pumpkin lifts up as it grows they will hold the vine down and you can end up with a problem. The 1236 grew two inches since I measured it at 8:00 last night and I noticed the vine wasn't lifting up at all this morning. There were some nice big roots on the nodes under and next to the pumpkin. One of the tap roots was a really nice cluster that was probably 6 inches long and 1/2 inch thick.
The 1161 saw some good growth last night too. First big movement I've seen on this plant so far so maybe it is finally making the pumpkin a sink or maybe the 1/2 inch of rain that fell last night helped push the pumpkin along. Cool weather today, tomorrow and Friday is in the forecast for Colorado so it will be interesting to see how the pumpkins react.
