Yeah, I've got some ripe pumpkins right now too, but not so much because I planted early. After an outstanding start in this new patch, I was hit with a super tough mid season...
* Lots of cucumber beetles
* Some mosaic type disease which I think came in with one of the seed varieties I planted
* Twice the normal rains on clay soil
* Some nutrient leaching
* Powdery Mildew started early (two weeks ago)
I've really fought my way through it, but yield and quality are going to be way down. I've learned alot. I'll post some pics, but it isn't as pretty as it was in late June that's for sure. About 4-5 more weeks until frost. Until then, I've found in the past I can store most of the fruit in the field if the vines are still going. But if the mildew really gets the upper hand, and the leaves are yellowing and dying off for whatever other reason... I'll pick off most all the pumpkins and store in the barn. I spray them with 10% bleach solution. It starts getting pretty cool around here come late August, and I've always been able to keep them fine through October.
I'm interested in what everyone else does regarding picking/storage.
