This year, I was late putting in pumpkins and decided to try this hybrid, which Pinetree describes as growing to large (jack-o-lantern) size in a relatively short period of time.
I planted the seeds in a mix of 50% garden soil/50% composted cow manure. Germination was a satisfactory 80% or so.
After emerging, these plants have grown remarkably fast! The leaves are huge and healthy, and the vines are spreading wide, just as Pinetee said they would. I'm VERY pleased.
At this point, I have no idea how many pumpkins I'll get out of my two big hills nor what they'll look like, but I'll try to "amend" this report after harvesting.
