They have probably grown tall because of one or both of two things - too much nitrogen or if they had to compete for light -(tall nearby plants). I think the guide here say 12-16 weeks to harvest. The leaves will die off when it is time to harvest. My plants powered along (fed plenty of composting mulch - then they have just died - only about 12 weeks since shooting out of the ground. I pulled out one plant - a few big potatoes and a few smaller ones. Have left the others in until I need them to eat.

Would this potato planting guide apply to sweet potato's as well?

Look under sweet potato guide on the website. Potatoes you plant in a furrow and then hill up as they grow. Sweet potato you plant in a hilled up bed. Best thing is to have a try.

Can I plant potatoes in normal potting mix. I have mixed it with perlite and Coco husk for drainage? It's in a 1.2M X 600mm veggie container.

Type in different ways to grow potatoes and read. Different ways give different results. You would have to keep the water up and probably use a lot of it.

I live in Brisbane and want to to grow potatoes in pots. When you say mound up do you mean to full cover the shoots each time or to just under the leaves

Just leave the growing tip exposed. Potatoes form off the main stem of the plant, not the roots. Mounding up provides space for the tubers to develop and reduces the chances of attack by potato moth.

Hi I have some small Kennebac leftover potatoes from my last years crop, they are all sprouting, however the guide says don't plant them till August, can I plant them now or is it just too early.

The guide says don't plant until August. That might apply in southern parts of Aussie or cold places but if you don't have frosts you can plant now. I live where it gets down to 5-6-7 C in Winter and I just planted mine this week. If you live in a low area and might get frosts then ??? - if you live in a higher area and no frosts, go for it. As my previous post said - wait until the eyes start to shoot and then plant. A tip, dig the soil deep, put in all the compost etc - then with a rake dig some of the soil out to make a furrow. Plant the potatoes and as they grow fill the soil back in. And then hill it up also around the plant.

I forgot to mention -- and kept forgetting to post this additional part. When you are "hilling up" you are actually burying LEAVES. Leaves have specialized tissue to COLLECT LIGHT -- that is to say, they are NOT ROOTS -- so to me, burying leaves is NOT CORRECT. It may help to get the potatoes producing sooner, BUT somehow to me if a potato plant made leaves it wanted to collect light -- roots are different, they are sort of thin and round/tube like and are used to transport water and nutrients -- AGAIN: leaves are leaves and roots are roots -- and when I stop and think about it burying leaves doesn't seem right... and my gut instinct is saying that it is not correct. I have also noticed that roots are thinner, and are probably easier for the plant to make/grow -- leaves look like they take a lot of work/nutrition -- so why bury something that is specialized to be above the ground???....... again, the pros may say otherwise and have lots of data and past successes to prove their view point. I have done it both ways (not sure why I did- but I did) and really have not noticed any differences in OVERALL potato production.... so why bury the leaves and make all that extra work hilling up ??? Also, potato tubers seem to like lots of air flow... so make sure the soil is light or ir your in containers ensure lots of holes near the bottom sides to create updrafts..
