The quantity of seed you would need depends on a number of things - how wide the rows are, how good the soil is, how you are going to cultivate them, etc. As a guide you would need 5-800 kg/acre. I would suggest you contact your local Primary Industries or Agriculture Department for a more accurate quantity. They will know your area and often have charts allowing for different row widths and planting densities to calculate quantities. Happy spud growing!

If you've not got anything else to plant give them a go. I have grown potatoes on the east side of the house which is shaded by flats next door first off then the house after midday. You're not likely to get the yield that you would with a spring-planted crop but any potato is better than no potato! Trust this helps.

Hi I live in Australia-Sydney. I want to grow second crop of potatoes. How can I do that and where can I get the seed potatoes for second crop during Dec-January? Thanks

You could certainly grow another crop of potatoes in Sydney. Unless you were a commercial grower it would be difficult to find'certified' seed potatoes at this time of the year. You could plant small potatoes from a shop. Leave them on a bench and let the 'eyes' start to sprout before planting. Do not plant them in the same spot you have just grown tomatoes, capsicums or potatoes as you don't want or need soil-born viruses transmitted.. 'Certified' seed potatoes are grown in tested, virus-free soil before being packaged and sold. 'New' potatoes can be harvested about a month after flowering and 'old' potatoes when the tops die off. All the best.

If I planted seed potatoes now (Feb 17) is there any chance I'd get a crop before winter sets in?

Potatoes need about 3 months to harvest from planting for 'new' potatoes. That is about a month after flowering. If you can get 3 months before frosts give it a go or plant them in a frost-protected area. New potatoes are delicious but won't store like Old potatoes which are harvested after the tops die off. Trust this helps.

Thank you Sandra re my question as to whether seed potatoes can still be planted in January where I live in the Dandenong Ranges Melbourne. I will give it a go then if you have successfully planted for three years. Happy Gardening. Heather.

Could you kindly please advise me if seed potatoes can be planted up until the end of January, I know they recommend from August when danger of frost has passed but unsure whether January is still suitable. I thank you for your reply.

Hi Heather, I am still planting and growing seed potatoes in the Adelaide hills. Growth atm is rampant, and yes I have bandicooted a few little ones also. I just plant in a 2 metre square, and cover with soil, throw what seedless weeds I have into the plot and then cover again with soil and straw. Not had a problem yet with January being too late in the year and been growing them like this for 3 years.

I live in Zone 7b in Arkansas. It's been an unusually cool and wet spring / summer. I planted four varieties in a prepared bed. (composted manure was tilled in.) The varieties were Pontiac red, Kenebek, Russet and Yukon Gold in roughly equal amounts, purchased prepackaged at a farm store. The seed potatoes were sown in rows 12 -18 inch spacing on Feb 28 by burying shallow, then covering with several inches of composted manure followed by several inches of straw, two bales on roughly 120 sq feet. I did not document when they sprouted but it seemed weak initially but success rate of sprouts was eventually good. The composted manure is weedy and so was the straw, eventually weed pressure was high so I covered with another layer of composted manure. ( I don't remember the date and the plants were 20 inches or so tall, some in blossom. ) Although at the time of harvest the bed was heavy with weeds again that worked long enough to bring in a harvest on June 4th. While harvesting the soil was still quite moist, only two or three potatoes had rotted and the yield was about 2 to 3 nice sized potatoes per plant with up to three small potatoes per plant too. I followed the harvest with a sweet corn. I contemplated a second potato planting but i think it will be too hot. I'm going to make a deep raised bed from pallets manure and straw out in a shady part of my homestead and try a few to see what happens. Hopefully that helps.
