Good Day which month is good to plant "Halloween Pumpkin"

The best time to plant pumpkins, squash, zucchinis, cucumbers, etc is when the soil temperature is 15-17 degrees. This is around the end of October in the southern states. Many people say 'after the Grand Final' or 'Melbourne Cup' time.

Planted Karadle Gray pumpkins late spring, they are still growing and prducing female flowers. it is now late March, when will they die of so we can pick the fruits. Peter

The likelihood of them ripening is fairly slim unless you don't get any frosts until late May. The vines will normally start to die off when they are ready. If you run out of time use them to make pumpkin soup or grate them to use in place of zucchinis in cakes or savoury muffins. Next season plant your seed in toilet paper cylinders or egg cartons so they will be ready to plant out in late October. Plant cylinder or egg 'cell' as well as it will rot.

Hi, there are pumpkins in garden with big flowers, about 7 crab apple size fruit on each of 5 trailing stems. In Dunedin, what care do they need to produce good fruit.. ie reducing amount of stems, reducing fruit on stems, mulching etc. Have lots of healthy green leaves, have kept them watered and off the ground on boards. Thanks for any advice you can offer. Last year possums got to my only beautiful pumpkin just as it was ready to harvest, so need to cover them this year!! Thanks Barbara

You are listed as sub-tropical but also mention Dunedin. If you live in Dunedin it may be too late for the pumpkins to ripen before winter sets in. Pumpkins need about 4-5 months of good growing weather to do really well. The best way to grow pumpkins in areas where the seasons are shorter is to plant them in toilet paper cylinders filled with mix about 3 weeks before the last frost is expected. Stand the cylinders in a container (for watering) and keep them in a sunny spot inside. As soon as the soil is warm enough, about mid November in Dunedin I would think you could plant them out (cylinder included, it will rot. Removing the growing tips when a few pumpkins have formed will definitely help the pumpkins to grow a good size. If the pumpkins don't develop enough this year grate them and use them instead of zucchini in cakes or savoury slice or muffins. Trust this helps.

Like to know when can i plant giant pumpkin in the western cape
20 Mar 17, Jack (Australia - temperate climate)
Pumpkins will grow in almost any areas as long as you have at least 5 months of good weather. They can be planted after the last frost (if you get frosts) and don't like being transplanted so plant them in small pots or toilet paper cylinders in early spring in a warm spot or inside to get a head start. If you use cardboard cylinders you can plant them in the ground and let the cylinder rot.

I see from the Gardenate planting guide that the planting time for pumpkins is September to December. I purchased butternut pumpkin seedlings from Bunnings in February. Is the selling of such seedlings out of step with the recommended planting season unethical? The seedlings have grown and there are currently 3 pumpkins visible. I am concerned that by planting them outside the recommended period they will not mature to completion.

Hi there, depending where you live I read on an abc gardening page in a sub tropical environment that pumpkins could be grown throughout the year .I put mine in late decmber and they are simply powering along with many fruit now softball size .I hope this helps.

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.
