3-4 weeks ago I lost most of the 827 Holland plant because "white foam" came out of the main vine and near the stem. Does anyone know the reason of this ugly white stuff? The pumpkin nearly stopped growing at 400lbs. I think harvest of this pumkpkin (great cross: 827x801.5Stelts) will be next week. The second pumpkin on the first sidevine is still growing a little bit (827x898Knauss).
