If you mean 'plough or dig potatoes in June' you definitely can. If you mean 'plough the soil and plant potatoes in June' it would depend on whether you get frosts in your area. If you do it would be better to wait until the weather is warmer as frosts will kill the new potatoes.

The information you have here is helpful, but what i need to know is the average growing time to harvest please. The plants are flowering and I'm wondering if that is an indication? We live on the Sunshine Coast and the potato's were planted in October, 7 months ago.

In Qld we plant potatoes in Autumn and Spring. St Patrick's Day is the general start time March 17th for Autumn. Spring is probably Sept. They take 12-20 weeks to grow - probably the warmer the climate the quicker. You can pick potatoes any time but to have mature spuds to store for awhile you wait until they flower and then start to die off. Have a little feel around to see how big they are.

I was talking to a friend today who planted certified potatoes about 8 weeks ago (the last of the hot summer weather) in sandy soil. The last ones to shoot out of the soil had stunted curled up leaves - like the leaves had not unfolded and grown bigger. He took them to a commercial grower to find out why. This fellow said it happened because the soil was too hot. Being sandy loam it probably retained the heat more in the soil. Out of about 35 potatoes about 8 had this problem. The commercial grower has only just planted his crop - Bundaberg Qld. He waits until the potatoes eyes start to shoot and then plants. Hope that helps.

Potatoes can take 14 - 20 weeks, when the tops die down to be ready for long-storage harvest. 'New' potatoes can be harvested about 4 weeks after flowering. These potatoes should be 'raided' without disturbing the plant too much so that others can mature.

I'm in eastern cape (engcobo) how much watering does potatoes need for a favourable harvest,and what time must I plant?

To produce good potatoes the plants need a consistent supply of water. In dry soils the potatoes will still form but will be small. Mulch can be used to save water. If the plants are wet then dry then wet again you will get irregular growth and knobbly potatoes with likely hollows inside them.

hi, just wondering if I can plant cucumbers after a potato crop. my potatoes are in a raised bed

Hi Ian, While they don't make good companion plants, there's no reason you can't grow them in the same bed afterwards. Don't forget to enrich the bed with plenty of compost first.

You should be able to. Cucurbits, which include cucumbers like well manured soil and a consistent water supply. Put a trellis up, this will keep you plants tidier and the cucumbers cleaner.
