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.

Pumpkins take about 3 and a 1/2 to 4 months to harvest from seed planting. This will give you an idea whether you will have ripe pumpkins before winter. They like lots of water and manure and often thrive from seeds in the compost. Water them at the roots to avoid mildew problems. If it is a running variety you can turn the vines back on themselves to contain them if you need to. Ripe pumpkins will have a dry stalk. Harvesting after the first frost (if you get them) will make them sweeter. Any unripe pumpkins are not likely to keep very long so you can make and freeze pumpkin soup or grate them into recipe sized quantities and freeze them to replace zucchinis in savoury muffins or slice.

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?

I have grown pumpkins 2 years in a row that have hard white lumps in them, I have bought a plant both times so I am thinking it must be something to do with were they are growing. Any idea of what could be coursing this?

Hi, I have the same problem. So far I have not found a definitive answer. Lack of water? Not last summer! Deficiency? Maybe, but cannot find any help there neither. Some pumkin have maybe one lump, others go to the cattle.

I am getting this mould or rust on my vegetables in my garden. It is causing many of the butternuts to die and the spinach to be spoiled. What could I do to prevent this?

try charcoal ash in your garden to prevent any diseases to the plants..

Do you know where I can get triamble pumpkin seeds from. I haven't seen them since koanga gardens had them.

surely it is not worth saving pumpkin seeds unless you have an heirloom variety? Most supermarket ones would be hybrids so they are unlikely to be true to the parent, and pumpkins are known to cross easily with cucumbers etc. Of course you would dry the seed if you are going to store them. Hardest thing with pumpkins is keeping the water up to them, they have so much foliage, they dry out easily.
