You could do both depending on how many squash you have. I had a couple of cuies that had 3 flushes of cuies. If I nipped the vine I would have only had 18 cuies - in the end I had 48.

I live in Te Anau and wonder what is a faster maturing pumpkin variety?? We had a good crop of pumpkins growing last year, but a rogue frost in mid March killed off the plant and the pumpkin crop did not ripen, and the weather is only coming good now (early Dec) to plant.

Look around some seed selling companies - email or phone them. Most times I see like 15-20 weeks to grow but which is early I don't know. Another way is to start the seeds early indoors or somewhere protected from the weather. You could start growing them in Oct say under lights. Sometimes nature throws us a big curve ball and stuffs it all up.

Most common is the Jarrahdale pumpkin - plant Sept to Dec and don't pick until vine starts dying - about 18-20 weeks from planting. Good fertile soil, lots of sun and plenty of water.

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?

Just found this - commercial production. For efficient pollination and fruit set, there must be: both male and female flowers and bees to move pollen from male to female flowers. A number of factors can influence pollination, Cold and overcast days limit pollination activity of bees. Hot dry conditions desiccate pollen making it unviable. Rapid growth promotes earlier flowering. However, high temperatures, long days and high rates of nitrogen can result in: vigorous vegetative growth and few flowers and a higher proportion of male to female flowers. It is important to check the sex of the flowers. A ratio of 1 female to 7 male flowers is usually considered adequate. Flowers open early in the day and for one day only, and they close by mid afternoon. These periods are shorter under high temperatures. Flowers are most receptive to pollination in the morning when bee activity is usually the highest. Bees are necessary for pollination and must be active in the crop. Flowers require at least 12 bee visits for good pollination. If bees are not plentiful, introduce at least two hives per ha after female flowers appear and male flowers start producing pollen. Spread hives around the field outside the crop, preferably so that bees have to fly over the crop to get to another food source. Destroy flowering weeds around the crop.
