in my little plot, soil is clay, hard as rock,,SEP2017 turnd it over 10cm, coverd it with lawn cuttings, from old compost, waterd it daily 1 week, turned soil over again,coverd patch ,,1 inch of cuttings,, layd old potatoes on the surface, coverd them with a few inches of grass cuttings, a quick water in morning, and at sunset, just enough to wet the grass cuttings,.. each week, or when ever I mow lawn, the cuttings go on the patch, .the foliage is large, beautiful flowers, have been picking since dec,, its a personal choice, I love them just bigger than a golf ball, , wait for a hot dry day,, let them lay in sun all day, bring them in before night,

I have had potatoes in the garden for a few years now. They just seem to be growing wild in the garden. Actually they are running amok. I was just thinking of turning the crop over and starting again with manure and mulch. Should I actually dig all the crop up and replant in an organized fashion or is it OK to just plant and harvest and enjoy nearly all year round.

Only you can decide that. Potatoes grow then the plant dies - why don't you dig the potatoes up then - that is the normal practice..

We live in Townsville and are wondering if we can grow potatoes here and if so when is the best time to plant them and also are they best grown in the ground or pots??

It suggests planting April/May here. I would suggest after the chance of cyclones - heavy rain. Plant in a raised ground so that the soil drains freely. You want the soil to be wettish but not water logged. Easier to care for when in the soil. In a pot you would have to be on the ball with the watering.

Going to plant potatoes in the pig paddock ( when the pigs have gone ) will their manure be too strong and can we put in old dried animal manure with them. We are down near the sea in the lower south east of SA. We have a red/black loam soil. When should we start planting?? Thank you

It would depend on how freshish the manure is in the soil after you take the pig/s out. Fresh manure has nitrogen - old dried out manure has very little. Old manure is more a soil conditioner. If you had looked at the guide here for growing potatoes - temperate climate - Plant Aug to Oct. You may be able to grow a crop from April/May. Read up about growing them.

I live in a very cool part of the Barossa Valley where the growing cycle is out by 4 weeks so what would be the best time for me to grow tatties?

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
