I put the kitchen vegie scraps in a blender (with water) and strain it through shade cloth then add the vegie scraps to my worm farm. The pumpkin seeds aren't smashed up and the other week I had about 50 seeds germinate.

I grow pumpkins every season. If you want your pumpkins to grow big you must make sure the entire plant gets watered and fertilised regularly as the vine sends down a root at about 1/2m intervals in search of water and food. When you start getting female flowers (with a pumpkin attached) you need to fertilise them by getting pollen from the male flower, just put your finger inside and you will see the pollen on it, gently brush it on to the middle of the female, once pollinated the new pumpkin will go into a growing frenzy, (I know they are about 90% water ) Water, water, water! And food, My best Kentia/ Jap went 12.2 kg 33cm high, save the seeds and keep them in the freezer. Veggies are the best.

Hi I planted pumpkins in mid November, they are still growing and i'm getting heaps of them. Do I just let them keep growing until they decide to dry off from the stalk? I live in Launceston,Tasmania

My Pumpkins are the same. Still growing like crazy and flowering. I thought they are supposed to be finished? This is my first time growing them down here (Victoria). I guess we'll just have to leave them until the plants die off.

You can buy a piece of pumpkin you enjoy and if it has seeds keep those. Let them dry before planting again.

I would advise against using shop bought pumpkin for seed. Most pumpkins grown commercially these days are hybrids that are bred to look like the well known varieties. They will not however produce true to type offspring. If you are happy to take pot luck then by all means go ahead and plant them, but if you really want a good tried and true pumpkin variety you will need to get seed from a seed supplier or a friend who has grown them before. Happy gardening one and all.

I planted my kent pumkins in September and have javested about 8 mature pumpkins...new pumkins are now starting on the same vine. Will they mature even though it is coming into winter?

Why are my home grown pumpkins watery? Not nice mashed.Would they make a nice soup.?

I have the same - maybe they might dry out if left for a month or so. Mine are jap - very sweet and moist. I probably pick them a bit early as I wanted to dig the garden up to plant other crops.

I am trying to grow pumpkin in raised beds without much luck. I have flowers that don't fruit. I have lots of bees in other beds but suspect there is a pollination issue. How do you tell the difference between female & male flowers, then how do I pollinate the female flower?

Hi Dawn, Unfortunately April is not the right time to grow pumpkins in Victoria as we are heading into winter. Pumpkins require a fairly long growing period of 4-6 months (depending on the variety) of warm weather and are they are very frost sensitive, so will die once winter hits. If you are keen to grow something now, cabbages, broccoli, Asian greens, lettuces, radishes and carrots are pretty good bets. If you have your heart set on growing pumpkin, best to wait till October/November for sowing/planting for best results. Cheers & happy gardening.
