I am trying to grow them and they are going alright at this point; I though I was going to lose them all together but I found out I was just watering them far too much so i pulled back on the amount of days i was watering them and I think they are doing alright cos I have pumpkins flowering. I am looking forward to eating them too.

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.

I am retired and live in Masterton and would like to grow pumpkins for a little extra income.My father grew triable variety in New Plymouth.Can they grow down here. Thanks

You should be able to grow pumpkins successfully in Masterton. About four years ago a little chap (3) from Masterton won the biggest pumpkin competition run by Mitre 10. To get a good start plant the seeds in toilet paper cylinders filled with potting mix and kept on a sunny windowsill. You could start them in mid-October ready to plant out in early November. Plant the cylinder as well to save any root disturbance (it will rot). Triamble is a great old variety. If you can get seed of 'Queensland Blue' it will probably give you a higher net yield per plant at an average of 17 kg. Properly ripened pumpkins always sell well. Try pubs, restaurants, etc. All the best.

Hi. A friend once gave me a triable pumpkin, it was firm when cooked and very tasty. He said that they take a long time to mature

From time to time I will have a pumpkin from my garden that when I cut it, it has white lumps in it that are hard and when the pumpkin is cooked it remains hard. Do you know what causes this, maybe something in the soil? something lacking in the soil? a virus? I would love to find out and see if I can avoid or cure this problem.

I heard that is has something to do with uneven watering or spurts of drought.
