I live in Central West NSW, when should i be planting my pumpkins?

No frosts, no problem! Get them going as early as you like! I have to wait till last frost is gone, early November but this year I'm going to get some frost covers and start them a bit earlier.

Hi my name is Caroline and I’m not from New Zealand, but I love pumpkins! I REALLY REALLY have the urge to carve a pumpkin but unfortunately they are all out of season in America. This might sound stupid but are pumpkins on the same schedule in New Zealand bc of the difference in climate? Like would I be able to get one shipped ?

I live in Adelaide and have a crop of Jap pumpkin, the vine is just starting to die back, with the high rainfall we are currently getting should I cut the pumpkins before the stalk dries? I fear the pumpkins taking on to much water and rotting.

Be judged by how old they are - should be 20+ weeks to be ready to pick. No good picking a half mature pumpkin. The rain should only be a couple of days. If the pumpkin are laying flat and have water around the stem, tip it out. If you think they are ready try one.

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.

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!
