Hmm! Digger's Club. Is it really worth joining? I have purchased seeds or plants from some places in the past that havenot been fruitful at all. Thnx.

hi, I have a raised garden bed 1.2x1.2x400, how many seed potatoes would be appropriate to grow in this area?
13 Jul 20, (Australia - temperate climate)
2 or 3 rows and plant 35mm apart.

I have bought some seed potatoes and prepared a raised garden vegetable for them. I have never grown potatoes before so am a total novice. The bed is 2m x 50cm x 40 cm. Can I plant a couple of different varieties together such as kipfler and purple potato and even if a third variety if I have the room?

A garden bed 2m long is only going to grow 6-7 plants. You can plant different varieties. Consider making the bed a lot bigger if you can.

i have read that you can grow them in a bottomless large bucket or a wired enclosure this way you just keep topping up the dirt and mulch when the plant gets taller until eventually you reach the top. once they are ready to harvest just pull the vessell you have chosen off and down they all fall. Saves using your garden and gives you room for more beneficial plants or vegies to use.

After you have harvested your potatoes can you re use the dirt with extra compost ??

The handbook-which I provided the location to in my prior reply is not very beginner'ish but it is comprehensive covering issues you may never encounter- but you do need the reference material. I have a few thoughts to add. 1. Hilling up while the plant is growing-if you are covering leaves I find this fundamentally wrong. Leaves are specialized and designed to collect light, they are not roots. So I opt to plant my seed potatoes deep enough on day one- however I tend to have the luxury of very well airated, light soil. This means the seed potato has a steady air supply and can sense the heat from the sun even at deeper depths 2. Your seedpotatoes need all their potassium Immediately. Potatoes strangely take up all their potassium that they need really early. -and don't uptake more. If there is not enough potassium in the very early stages your potatoes might have hollow heart (looks like hollow rotting middles). Late application of potassium tends to be useless 3. Potatoes seem to respond really well to the addition of microryzal fungi - in my area we source that under pine trees in a forest- we just take some forest floor duff with a dust pan and add to the potatoe planting soil. To sum up - your seed Potatoes should be about the size of chicken eggs (if larger cut up ensuring an eye on each piece and allow a few days to heal/scab up before planting). You need to chit them(make them sprout-place in dark so they sprout). Plant in soil with Compost, a sorce of potassium and microryzal fungi. If for some reason you cannot source any compost/pottasium/microryzal fungi -plant anyhow potatoes are tough -there is still a good chance they will be Okay -depends on the condition of you soil. In my area I can water deeply once per week. Harvest when about half the leaves have fallen over as if to die. If you harvest sooner you may be compromising on size-because as long as those leaves can collect light they can store the energy in the tubers. Good luck - it is so much easier than it sounds- and all those diseases in the handbook are rare and if the plants are strong (well fed) they can manage just fine, potaoes are pretty tough root crop. In other words- you can grow potatoe.
