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.

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

Hi. We live in Zone 9. We were able to get beautiful pumpkin plants and florets, but never produced a pumpkin this year. We know they can grow bc there is a pumpkin farm nearby that produces plenty. I thought that I had only males, but then female plants appeared and still no flower. We started them in Late July, I think. Any advice?
