Like all curcubitae, planting time is when your soil is up to 20C. Definitely after all risk of frost is over

When is the time to grow pumpkin, cauliflower, mandarin. Thank you.

In HB, pumpkin planting of seeds you've stored from last year gets underway in early October. They're easy to grow, plant deeper than 3 cm if birds may dig them out. They will ramble everywhere in your garden! ....Plant mandarins before November. Mandarins do fine semi rural in HB with no frost protection. But once a year, you need to spray them with oil as they can get sooty mould. The sooner you spray the better if the leaves start showing this black mould as it spreads. I hate spraying if there are bees around so check this out first. I underplant citrus with allysium as this little flower is meant to discourage bugs.

Why is it recommended to avoid growing pumpkin near potato plants?

Why should you avoid planting near potatoes

Not growing pumpkins with a potato crop is a falsehood . An easy way to grow both together an have a good cropmof both is to let the potatoes grow and when well established and moulded up at least twice after all frosts .I always throw a rotten pumpkin onto the potato patch and along with all of the pumpkin seeds collected from those which have been used . A good crop of both pumpkins and potatoes always happens .The pumpkins help to suppress weeds and are good companion plants for spuds .

I live in Wainuiomata and have grown gems for two years running and I intend to plant a lot more this year. They were delicious. I planted the seed at the end of August and as soon as they had about 4 leaves, I planted them out in the garden, I also cut off the bottom of a coke bottle, took the cap off and put the bottle over the seedling until they were a little stronger. Hope this is helpful and good luck.

You could but they may not produce a crop, stick to the planting guide here - that is what it is for.
