Can a potatoes be grown in self wicking containers or would they get too damp?

Potatoes can be grown in wicking beds. If the beds are set up correctly they will only 'wick' the water that they need.

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.

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.

We seem to have potatoes coming up for most of the year. You should still be safe to plant now even if you only get 'new' potatoes. New potatoes are ready about a month after flowering has finished. The skins rub off easily on new potatoes but won't on old or fully ripe potatoes. Trust this helps

It depends -- not all potatoes are suitable for towering (layering). Additionally, I have found that the potato plant SPENDS A LOT OF ENERGY GROWING UP, UP, UP, as you cover its leaves with soil (leaves have specialized cells designed to collect light - and why you would want to cover them with soil is beyond me this is not really a good move -- leaves are not roots). My recommendation is: if you have a DEEP PLANTER bag starting at about six inches from the bottom -- in sort of a pattern that looks like the 5 on a die (dice) -- make about 3-4 inch round holes -- and make them on the sides that receive light keeping the holes about 10 inches apart (6 inches away from the bottom and 10 inches away from the top of the bag). Fill the bag with a good soil/compost/manure mix of some kind -- starting from the bottom -- when you are level with a hole, place a seed potato there, level or slight below the bottom lip of the hole, and about 3 inches from the side of the bag (so there is soil between the potato and the hole) -- continue up until the bag is full -- the top layer of potatoes can be planted as usual. Yes, the soil will come out of the holes ... not to worry -- just be sure that the soil covers the topmost holes by at least 6-8inches. That is - each potato planted in the bag should have access to a WINDOW (air and light) OR those planted on the top layer (like a usual planting) should be down about 9 inches or so. The Key to this planting is ALL potatoes need to be able to put leaves somewhere -- they will follow the air and light to find that spot -- all potatoes need water -- so you will be watering from the top of the bag only (like a potted plant) -- but you water DEEPLY, since the water needs to make it to the very bottom potato plants -- so maybe you water every 5 days or so... depends on the soil, temperature, amount of light , amount of wind/air (which whisks moisture away), Additionally, ensure there is drainage at the bottom of the bag .... maybe a two inch hole directly at ground level. It might be better to use a crate of some kind.... rather than a bag...anyhow this set up will work with any kind of potato plant without consideration as to whether or not it can handle towering. Hope this helps. Conversion of inches to cm : 1 inch = 2.5cm
