I see that I should avoid planting pumpkins with potatoes. But how far apart do they need to be? Is opposite ends of the same garden bed ok? Thanks.

Depends how far apart you planted them - ends of a bed doesn't tell me much. Take into consideration how far the pumpkin plant will spread - could be 5-6-7m. Do you want them running through your potatoes. I would suggest planting any vine crop away from smaller crops.

I have saved seed from a pumpkin we like and allowed to dry. I am soaking some in water and some in a damp paper towel and left some dry. None are showing any sign of striking. Do I just wait longer or will they strike if I plant some out?

Take a plastic tray you buy your meat or chicken in from supermarkets - 2-3

Pumpkin seeds will take about 7-10 days to show any activity. Your best bet is damp paper towel or seed raising mix. As they are frost tender, pumpkin seeds need some warmth to start germinating.

I have pumpkins that have come up in my garden .They came up in November and are white skins at the moment.I live in Rangiora North Canterbury.I don't know anything about growing them.Do I leave them in as long as possible as I don't know whether the frost or rain will affect them. Thankyou

Hi Toni you can stop watering your Pumpkins now. After you have a frost the leaves will die off. After the leaves die off you can harvest them any time now. Leave the stem on and store in a place with good air supply and sun to ripen. You can check the ripeness by knocking on them with your knuckles listen for a hollow sound which indicates ripe. Enjoy Jim

Wait till the plant dies before harvesting.

Above it says 15-20 weeks to harvest. Take notice of when to plant and how long to harvest.

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.
