I am on my third year of the same vine (essentially) with butternut. I'm currently trying a new angle with them and wondering if anyone has tried similar. I was losing a lot due to it sitting in water constantly. Grey water from kitchen sink, bathroom sink, dishwasher and washing machine all runs through the area. This year I have built a tunnel and have been weaving it through like a creeper and am now trying to train it to go up and around a fence. Has anyone had any success with "climbing" their pumpkins

If you let all that water into your vegie garden then your soil would be WAY TOO WET. I am surprised any thing grows in it. I suggest you move your garden bed or the run off water. Or raise the garden height. They will grow on fences or trellises. I have some Kent doing that now.

Hi, this is the first year I'm growing Butternut pumpkins. I live in Tasmania near Launceston. I have lots of new leavers and the plants are spreading nicely. Can you tell me when I may get flowers please?

I haven't grow butternut but I have Kent pumpkin growing now. The vine did grow out about 1.5-2.0m before the male flowers came out, a few days/week later the female flowers should come out. Hope you have bees otherwise learn about hand pollination.

Hi Something is eating the pumpkin leaves They were planted around mid November so they are around 6 weeks. Thought it might be snails but no sign of them. Any suggestions in what to look for? Cathy

May be little lizards/geckos that is what I am currently fighting with

Actually, if you just have small skinks or geckos in your vegetable patch, this is a good thing as they'll be feeding on any potential pests (well, they may not necessarily discriminate between what insects/invertebrates they feed on!). Anyway, I have many small skinks running around my garden/vegie patch and I consider them a sign of a relatively healthy garden. My best advice for looking for pests is to sneak outside at night and see what's happening. Many pests are 'nocturnal' or easier to spot at night. For example, root weevils (which love my basil!) and green caterpillars (loopers) which may be a culprit of pumpkin leaves. If you look for leaf damage that looks somewhat like a mosaic of holes, turn the leaf over and I can almost guarantee, you'll find a little green caterpillar smiling at you!

Snails come out at night I think. Early in the morning or late afternoon check the leaves for grubs.

You could grow the Turkish pumpkin, you would have to plant the seeds mid winter and have warm soil to germinate the seeds.

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.
