Mary, I'm growing potatoes for the first time this year and the heat knocked mine around as well. However, with plenty of watering and the cool change we've had this week, they have come back.

Teashy, potatoes often resprout after a shock like that, have faith, and they could be okay. In my climate, they often get frosted off completely, but then come back from the dead. Mary, potatoes have a really hard time in the tropics/sub tropics. I think there will be some years when there is just too much against them. This year seems to be a bit hotter than normal, so maybe they have a few too many bugs this year, combined with the unusual heat, it could just be a year to concentrate on other crops. If you plant them in the shade, they will do a lot better. It isn't too late to plant some fresh ones, and don't put them in direct sunlight. They are quite tenacious, and will grow in quite low light. The reason they didn't develop more taters is, as you rightly point out, that they just didn't have the time to grow to their full potential.

My potatoes were eaten by the big ladybirds and grasshoppers. The recent heat finished them off. I dug up some today and there was a small number of developed potatoes but not as many as there should be. Is this because they did not get to flower? I grew them in old plastic garbage bins and filled them with mulch as they grew. There was no potatoes until I dug down to the dirt so what is the point of "hilling" them?

I have had my potatoes in for maybe 6 weeks or a little bit more, due to the extremem heat we have been having the leaves have died very quickly and all I can see is the dirt underneath. Do I just leave them in and hope for the best or do I pull them up? Any comments or hints would be greatly appreciated. Many thanks

I am growing potatoes in inner melbourne, in a tiny back yard plot. I planted farm potatoes from ballarat and they sprouted quickly and grew about four very healthy looking plants. I decided to stake them or at least support them and they grew to about 1.2m. I rarely remembered to build up the soil around the stalks. Now green caterpillars are decimating the plants and they are looking terrible. They haven't flowered. Should I leave them in or forget this crop and try again next year?

Some of my potatoes have curly leaves and the actual potatoe is split, would this be the heat.

i grew potatoes this year. kipfer sebago and pontiac. i put heaps of compost into the garden and all my potatoes went really spindly and leggy they had plenty of sunlight and all the potatoes that i harvested were quite small, have i put too much compost/manures in my garden beds? everything else seems to be doing fine...

Do the tubers grow along the stem or on the roots? A friend says hilling the plants is so that more tubers grow - is this right? How do I know when to lift them? Is it when thee flowers die down?

Hiya Cons, The reason you hill-up potatoes is to cover any potatoes that are close to the surface, as these potaoes when exposed to the sun will go green. Green potatoes are inedible as they are poisonous. Cheers

Hi Ryan, A quick Google search returned this: Potatoes are ready for harvesting when the majority of the tops have withered. Early potatoes may be dug for table use at any time but for storage the potatoes should be fully mature. And Adrienne, Seed potatoes should be kept in a bright, warm position when trying to get them to shoot. Keeping potatoes cool and dark will keep them from shooting.

I started planting a variety of spuds mid Aug in Melb, normally after frost danger was over. End sept when plants were around 15-20cm high we had severe frosts and plants got badly burned off. Surprisingly, they recovered well only to get hit hard again 3 weeks later, Once again they recovered. I have just started ferretting out a few early spuds and the crop looks like being one of my best ever. Has anyone ever tried reducing leaf growth by removing some of the tops to see the effects on the crop?
