What is the best way to water pumpkin plants? Do you water near the original base or do they grow roots elsewhere?

The best way to water pumpkins is at the roots as overhead watering will encourage mildew development. And, yes they do send down roots from the running stems so if you can trickle water them it will definitely help. Trust this helps.

December I noticed in my garden an unusual plant growing from kitchen compost . Now at the end of January it has spread over the lawn, someone said it was a pumpkin, I can identify many fruit forming, like a glob shape with yellow flower,, and long stems with yellow flowers the fruit is a light green color.How can I know at this stage, it a pumpkin, and not a weed. thanks

It is fairly likely to be a pumpkin from discarded kitchen scraps. It could also be a melon, cucumber or sqush if youu have eaten them. The flowers with the long stems are the male flowers which will pollinate the flowers with the round 'glob' on them. Compost grown pumpkins usuall thrive so it sounds like a bonus! Trust this helps.

My pumpkins are just forming "tenis ball size" with only 30days or less until it gets cold. I have planted late, November late but it's not made much difference to zucchini & cucumber but I'm hoping for mature pumpkins in 80days. Has anyone else had mature pumpkins by then?

Depending where you live you would normally get warm weather into Mid-March. If the pumpkins aren't ripe by then make pumpkin soup and freeze the excess or grate them into zucchini recipe quantities and freeze them in stead of zucchini. Sorry I can't help more.

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?
