I live on Sydneys Northern Beaches. I have my pumpkin vines growing flat out on my lawn. Maybe 3 months since planting from seeds. I notice they produce many flowers but as yet most have dropped off and none have turned to fruit. I have possums and Bandicoots around but dont think they are causing the issue. How can I please keep the flowers from dropping off? I keep the water up to them and have used seaweed solutions a few times and added fertiliser pellets. Thanks for your help in advance

Live in Melbourne and had the same problem... Then I started hand pollination and fruits were setting on 95% of my female flowers

I suggest you look up on the internet how to grow pumpkin. Look up how pumpkin needs bees to take pollen from the male flower to the female flower. Look to see if you have any plants flowers in your yard/neighbour that attract bees. Otherwise learn how to hand pollinate the female flowers.

Does any one know why the we have to hand pollinate pumpkins - the bees used to do it when I was a child?

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

I see we should avoid growing pumpkins and potatoes together. I have 2 vegie gardens, they are about 8 meters apart. I grew potatoes(sebago?), tomatoes (gross Lizze), and for the first time capsicum and lettuce in the big one, and jap pumkins in the smaller one last year. Lettuce were great until a hail storm hit, tomatoes, potatoes and capsicum all went well. But the pumkin in a virgin patch went ok, although some fruit did not develop. I had about 8 vines, and at one point there were 25 fruit starting to grow. Some of the flowers did not even open. Others got bulb end rot. I got about 10 good pumkins off the patch, which I think is ok considering it is smaller than recommended at 2 by 3.8 meters, and it was the first time anything had been grown in the soil. Did I have a lesser success with my pumkins because the potatoes were close by? I did have to hand pollinate a bit. What are the main reasons for not growing spuds and pumkins together?
