They haven't been pollinated. Try transferring pollen from male flower to female flower.

Select your climate zone, then go to the vegetable you want and then look up the planting guide. NZ cool climate plant Oct to Dec.

It is about 4 months too late by the guide here. It is not the temps now but what they will be in 4-5months time when the pumpkin are suppose to mature.

Hi there, I am in Sthn Gold Coast. Am I able to plant a butternut pumpkin in a very large pot (for root growth) and then let the vine trail over into the garden. My soil isn't very good, by using a pot I can buy good quality soil / potting mix. Would this work? Thank you, Sam.

Yes it would work - need to water regularly and also fertiliser now and again. Amazing what a little compost and fertiliser can do to poor soil.

I have a kent pumpkin vine that is producing huge fruit. The vine is still very healthy, but the pumpkins are easily 5kg each already and don't show any signs of slowing their growth. Any tips on when to harvest? I don't want to lose the lot, but i also don't want to pick too early. I live in central QLD and we have had a fair wet season.

Hi, I’m based in Brisbane and have my second season of pumpkin plants in the garden, japs and blue, most likely. This lot have just sprung up from compost that wasn’t fully decomposed that I used to plant some sweet potatoes and other things in. My pumpkin vines are wilting quite badly and I have just read a bit about the cucumber beetle spreading bacterial wilt, which I will check for ASAP. Just wondering, if I do find the sticky, white strands, indicating bacterial wilt, do I need to pull out all of the effected plants? If I don’t find the bacteria present do you think the wilting may be caused by a bacteria in the compost? I thought the plants were just super thirsty so I was watering nearly daily but today we have had quite a decent amount of rain and this afternoon my pumpkin leaves are still wilting but when it cools down they have sprung back up again. It really hasn’t been very hot today, which is what encouraged me to research and ask.... Thanks in advance for your advice. Bec
