Hi , I have just acquired a large pot , about 500 litres In Tasmania last month and purchased some seed potatoes , about a kg of mixed variety Going to drill some holes in the side of the pot at the base , add some plastic grating , old bread tray . add a couple of bags on potting mix and plant the spuds . I am thinking of then adding straight mushroom compost from the mushroom farm covering the plants as they grow ( after about 100cm ) leaving some fresh growth on the top. will the mushroom compost be enough , I can get a box trailer load for $30 from the mushroom farm and it has a mixture of what looks like black compost mxed thru it

Jenny, the problem with potatoes planted now is that any frost will knock the tops off. If you are in a frost free area or can arrange a frost free micro-climate for them, then you can certainly plant potatoes now. I have a number of volunteers growing at te moment, but I don't expect them to last unless I cover them well. Don't expect too much growth for the next couple of months, though.

I put my new potatoes in on the traditional day Good Friday although that will be different for anyone in the Southern Hemisphere lol. As mentioned before they don't like frosts. Anyway, I make sure I plant them on lots of well rotted manure and earth them up when they start showing. I grow new spuds in containers and earth up with a mixture of compost and grass clippings which are free and easily available when I can be bothered to mow the lawn ! Potatoes like water and muck. When you harvest them they taste nothing like shop bought spuds !! Good Luck !

Had my kipflers in the ground now for 2.5 weeks and all have shooted and growing quickly. Will mound some more soil and compost over them once they are all around 10cm high. Looking good so far!!!

Re Tamworth potato. Be a devil and try whatever whenever. I use garbage bins suitably placed under tree and to get reasonable sun. Have had decent results from early planting and planted new crop today. It is amazing what will grow where conventional wisdom says "no way". Just don't leave out directly in the frost. Same with pineapple. Go on...have a go.

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.
