    Pumpkin on vine

A large trailing plant with yellow, bell-shaped flowers, pumpkin is frost tender. Most varieties will take up a lot of room . Grow them at the edge of your garden patch so that they can spread away from other vegetables. Butternut produces small to medium pear-shaped fruit with deep orange flesh . Buttercup are small to medium round pumpkins with dark green skin. There are a number of large pumpkins, some round and flattish - good for storage and eating - others will produce the "Cinderella coach" type giant round fruit which are not such good eating.

Harvest when the vines die off and the pumpkins' stalks are dry. Leave a small piece of stalk attached to the fruit to prevent damp causing rot. The fruit can be stored for months in a cool airy place. In some parts of New Zealand, they are stored on shed roofs.

Pumpkins sometimes need hand pollination if the fruit are not setting well or die off after starting to grow.

Culinary hints - cooking and eating Pumpkin

Cut up, remove the skin and roast with other vegetables or meat.

Young crisp shoots with young leaves can be cooked and eaten - stewed in coconut milk they are popular in Melanesia. Remove any strings and tough parts and stew until tender, or cook as a vegetable in boiling water 3-5 minutes.

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

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.

Pumpkins are best planted when soil temperatures have reached 15-17 degrees C. This varies between climate zones, Australia is a large country. A soil thermometer is aa good investment to check this. They usually cost around $20.00. If you plant seedlings in February you would need to have about 4 frost-free months to harvest. As for ethics many companies sell what looks good or what people want. Tomato plants are available in Victoria as early as July. They will not do well until mid to late October when the soil has warmed up and many will die. This suits the seedling growers as they will sell more plants as replacements. Having said that if you have a sheltered spot you could get tomatoes going earlier. The best thing to do is to check the planting times on this site relevant to your area and don't be tempted by what's on offer.

Try some heritage pumpkins. Seeds on bid or buy or direct from Seeds For Africa or Livingseeds. Remember as much compost as you can use. If possible plant straight into the compost heap. Watch for powdery mildew when night temperatures go down or long wet humid weather prevails. It will knock your plants down in days.

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.
