It says Sept to Nov for summer rainfall so probably best not plant now.

It suggests you plant Mar April. You grow potatoes from potatoes not seeds.

Most people grow potatoes from “seed potatoes”. Some people chose to grow their potatoes from actual seeds – think tomato seed. These seeds are called “True potato seeds”. The reasons to grow potatoes from TPS are numerous. The main reasons tend to be: more variety, and cultivating a variety that is well suited to your conditions. When the intent is to cultivate a variety well suited to your taste and growing conditions you generally purchase a package of say Andean TPS. This package will contain MANY different kinds of potatoes: flesh and skin colours. It will also contain short day, day neutral and long day potatoes; their ideal climates may differ. The idea is to grow as many of the potatoes as you can first year; some will grow well, some will not grow, some will grow poorly and some might just LOVE your place. Some will set a lot of potatoes, and some will set fewer; the idea is to find the potato/potato plant you like best – then save those potatoes to use as seed potatoes next year. In the first year you really don’t expect to have eating potatoes – it’s a year to find your potato variety. When growing from TPS you start the seeds early indoors, like you might do for tomatoes. Then transplant outdoors at the appropriate time.

When looking at your growing seeds/plants this may help you figure out what is going on: Analyze the flower: Anther can be Red, blue or yellow/white. For Red or Blue Anthers: Red Anther, red skinned potato. Blue Anther, blue skin. The petals of the flower tell you the flesh colour: Red petals, red flesh, blue petals indicate blue flesh, yellow/white petals indicate yellow or white flesh For Yellow/white Anthers: you have yellow white flesh and the petal tell you the skin colour. It should be noted that red is actually more like magenta, and blue is more like lavender or violet; the experts call them red or blue; because your looking for the presence of red or blue which will indicate the presence of red or blue in the tuber. Also saturation of the colour varies from light speckling to deep saturation.

Sorry for the late post -- I think I have the information you are looking for. First NOT ALL potatoes are suited for "tower" growth. So the first question would be how deep are your bags; if the bags are deep enough to be considered a tower, then you need to cross check this with the variety of potato you are growing. Second: when you plant a piece of potato (seed potato) this is your LOWEST POINT. Generally, a potato plant will not produce/store and tubers (potatoes) BELOW the level of the seed potato. This is why people plant the seed potatoes, wait for the green leaves to come up, and mound soil, always leaving enough leaves sticking out to collect light. You'll also note at harvest, that the lowest potato seems to have rotted; this was your seed potato that grew the plant. We plant the seed potato shallow, so the leaves get to the sun sooner/easier and start collecting light; then we mound the soil so there is room for the potato plant to set its tubers (potatoes) -- this means, that you plant you seed potatoes at the bottom of the sack, covering them with several inches of soil, and as the potato plant grows, you add soil.... always try to leave plenty of leaves sticking out of the soil so the plant can collect sun. Hope this help. From the Eagle Creek site (about their tower potato mix): Not all types of potatoes are suited for container growing, typically fingerling and late season varieties yield best. Bellanita, Bintje, Amarosa & German Butterball are the 4 varieties in this package.

You plant near the bottom and add more soil as they grow. There is more information on the internet about growing them this way.

Technically you don't HAVE TO HILL any variety of potatoes. Here's how it works: you plant the seed potato (which is an extra small potato saved/stored from last year's harvest -- or a piece of a larger potato that you stored/saved from last year) -- the DEPTH THAT you PLANT that SEED POTATO determines your LOWEST POINT -- GENERALLY, and I do mean GENERALLY (like 95% of the potatoes) the potato plant will not create tubers LOWER than the depth you planted the seed potato at (so your seed potato is the BOTTOM of the plants tubers/potatoes). Which is why some people think the very bottom potato always rots, when in reality it is the seed potato and is expected to grow and will appear rotten. Which means if you don't hill up as your potato plant grows and you planted the seed potato shallow, there is not that much ROOM for the potato plant to put it's tubers, and larger tubers will usually "pop" out of the soil and turn green due to sun exposure. If you don't want to hill up, plant your seed potato deeper than recommended -- yes it will be fine -- the reason you plant shallow and mound up is because the potato plant will be able to get leaves into the sun sooner if it's seed potato was planted shallow, which means it will grow quicker because it is collecting light sooner -- then you mound up to offset that you planted the seed potato shallow, but you always leave lots of leaves exposed to the sun so the plant can collect sun and grow. It's a lot of extra work work to mound up soil-- and maybe speeds up the process "brings in the harvest" by 10 days or so.... My experience is planting seed potatoes a foot deep ((30cm) is fine -- yes the plant takes a little longer for it's leaves to surface -- but it's fine and you should not experience any problems - provided the soil is nice and loose. (hopefully that makes senses). I think in the future I will plant two potatoes side by side -- one deep, one using the mound method and record the progress and final outcomes... I have never done a tandem planting -- BUT I HAVE had potatoes spring up from deep down Once as I dug out one of these "self planted potatoes" I realized it was down about 30" (70cm) -- it was in a potato planting tower (old full size garbage can full of 3" holes all over) which I dumped and collect the potatoes from the year before, then just put the soil back, week by week, as I composted kitchen scraps directly into the soil... so no surprise that a potato was so deep -- it grew -- it put out potatoes and it's crop was average good... it spent a lot of energy growing up -- and perhaps I harvested too early based on the other potatoes-- but it made it and did OK, good size potatoes, good quantity. I would not recommend placing your seed potatoes that deep, but a foot (30cm) should be fine.
