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 .

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.

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

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.
