It is fairly likely to be a pumpkin from discarded kitchen scraps. It could also be a melon, cucumber or sqush if youu have eaten them. The flowers with the long stems are the male flowers which will pollinate the flowers with the round 'glob' on them. Compost grown pumpkins usuall thrive so it sounds like a bonus! Trust this helps.

My pumpkins are just forming "tenis ball size" with only 30days or less until it gets cold. I have planted late, November late but it's not made much difference to zucchini & cucumber but I'm hoping for mature pumpkins in 80days. Has anyone else had mature pumpkins by then?

Depending where you live you would normally get warm weather into Mid-March. If the pumpkins aren't ripe by then make pumpkin soup and freeze the excess or grate them into zucchini recipe quantities and freeze them in stead of zucchini. Sorry I can't help more.

Is late January too late to plant pumpkin in Tauranga?

A year or so ago I was up that way from Christchurch for a holiday it was April, we saw heaps of people growing pumpkins so I would say go for it but keep them well watered as they like lots of water. And harvest when the first frost hits. Foot Note: I would start them of in seed trays first, in a glasshouse if you have one but not always necessary. If you where down here I would say no?

Hi you know what Noluthando every crop takes 4 months to be ready, the first day you plant you must write down and count the days from day of planting and you will be able to know when to harvest, even the leaves show you when its time to harvest, they get dry from 3-4 months.

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.
