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.

Try and keep the bottom of them dry with straw wet weather. Growing time is 16-20 weeks. The stem will become dry and hard and the yellow part will become dull. When you do start to pick just pick one and try. But think around 18 weeks +.

I have had several pumpkin plants pop up from seeds. I don’t know where the seeds came from as I’ve never grown pumpkins in the past. Never the less the plants grew vigorously with lots of leaves and flowers. I noticed plenty of bees around so assumed pollination would occur, however no pumpkins ever appear. I guess an experienced gardener would know what’s happening. I’m a beginner so I would welcome some information. Thanks.

If your vine is not producing pumpkins there may be a problem with pollination. Go to You Tube and search "how to hand pollinate pumpkins". They will give you a better description of the process than I can. Apparently its pretty easy. Cheers Pete

You would have had to noticed if the bees went onto the pumpkin flowers or not. I recently had bees working on some flowers and not the zucchinis 2m away.

Every year I plant pumpkin seeds with no success. But late in the season self planted seeds grow and I’m lucky to get one pumpkin before the frosts come. What am I doing wrong..

The biggest mistake with pumpkin, beans, peas, corn etc is they are over watered and rot in the soil at planting time. Too much water and high temps cause them to rot. Temperate zone planting is Sept - Dec. To plant in Sept to mid Oct probably requires to have them in a warm place or indoors to germinate. Try and use a light soil/potting mix/seed raising soil. Or even a combo of these with some perlite. You want the soil to drain freely. Prepare your pots or garden soil and give a good watering, then plant the seeds, don't water again until day 4-5 and only lightly. Or another way is to place some paper towel on a plate, put your seeds on the paper, cover with another piece of paper towel. Give this a good watering and drain off the excess water. Re wet it morning and night draining off the excess water. When the seeds have sent out a tap root plant them into your moist soil.

Cut them open and see if you have big fat seeds. If so they should be ok. Sometimes better to just go to someone like Boondie seeds and buy 4-6-8 seeds for $1.50-2.
