Depends how progressed they are. Vine die back only happens at the end of the vine life. I pick many Japs well before the vine dies, with other later pollinated pumpkins still growing. Excess moisture does not only create rot, but also splitting. If the pumpkins are getting yellow, ghosting, coloring around the stem base they could also split from over watering, so pick them. If they are still young leave them. I picked several Japs this morning, one was 7.2kg and it was only 31 days from pollination. (Central QLD)

Gramma pumpkin. When is the best time to pick? When fully orange and dusty. Is it ripe when green and dusty looking?

About 20 weeks or so after planting. The vine will be dying back, the stem from the pumpkin to the vine will be hard and dry. When you think it is ready try one, if a pale colour then you picked too early.

I live in NW NSW, possible frosty weather is coming this weekend. Can I cover the pumpkins with something to protect them till they are ready for harvest? Thanks

You can only give it a try. Take it off during the day though.

Butternut Pumpkin seedlings have popped up in my worm farm. Removed and put some in pots. They are growing. Is it worth planting at this time of the year in Brisbane?

Okay, just that it was a very sweet butternut pumpkin so I have dried out the seeds and will plant in September. Thanks for the advice everyone, it is always great to get something for next to nothing. Happy gardening!

I have been hunting for ages for the seeds of the Iron bark pumpkin, and so far have not been successful. Does anyone know where I can get them? They are a beautiful dry excellent roaster, and make great pumpkin wine! I also am growing something that lookes like a Jap, but has the shape of a butternut. They were self sown, too.
