You should have done this in preparing the soil before planting the seeds. You need composted manure. Fresh manure won't do much for weeks until it is composted. Your plants will tell you how they are going. Good strong green looking plants don't need a good kick in the guts. Pale yellow weak plants do not have enough fertiliser.

My pumpkins have sprouted out of some compost I put in the soil. I though they were QLD pumpkins but they are still a light yellow colour, will they turn grey or should I pick them.

I have only grown Kent pumpkin the last two years so I don't know much about the other varieties. But a mature pumpkin yellow sounds maybe like a different variety. Doing a bit of reading on the internet might help. Don't pick pumpkin until they are about 18-22 weeks old, the vine will be dying off and the stem holding the pumpkin to the vine will become hard.

Be careful using your grey water on edible crops due to pathogens

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 have been growing Queensland Blues & Jap Pumpkins here in Sydneys West for a while and would like to know the following : Male flowers are plentiful usually at the start of the vine & female flowers are not as many but as the vine lengthens more females appear, so how far do you let the vine grow. If cut does the right ratio of flowers continue shoot or that stops everything, what you have is all you get and do you plug the cut end to prevent disease getting into the vine (read that on the net) Also everyone says when the vine withers pick your crop, mine was going great and green but I picked them (stem still green & firm) as I felt they were large enough but several had started to rot inside, we saved them luckey as another couple of weeks would have lost the lot. So how do you know when to pick. heard about tapping it sound hollow its ripe, pick a piece of skin with fingernail the skin can give you an idea. Noticed in the fruit shop many pumpkins have fingernail pieces dug out ??? somebody know something !!!!! As the pumpkin is pollinated & starts to grow do you sit it on a tile or similar keeping it off the ground ( for air & warmth circulation) sometimes when left on the ground the under side looks soft and worms and bugs seem to love that position.
