Planting potatoes:

Growing potatoes in the veggie patch couldn’t be easier, and it is also easy to locate seed potatoes in Perth. Dig a mix of compost and sheep manure into the soil and let it settle for 2 or 3 weeks.  Make a shallow trench about 20cm deep and plant the seed potatoes with the main eye pointing upwards.  Use a rake to back-fill.  If the soil is very acidic, add a little lime to the surface. 

Once your potato plants are about 15cm tall, mound some soil around the stem of the plant. Do not bury too much of the plant at any one time as this will inhibit the growth. The larger the mound of dirt you end up with the taller your plants the more potatoes will be able to grow. Lupin Mulch, and straw are also fantastic to use to mound up in between each layer of soil.

After 20 weeks the potatoes will be ready to harvest. You should have potato mounds that are about 30cm high. Not all potatoes flower so don’t rely on that being an indicator. The best way of knowing is to dig a couple of tubers up and check their size.

Storing potatoes:

Table potatoes should be kept in a cool, dark place.  Do not refrigerate as temperatures below 10°C can cause them to blacken when cooked.

Notes:

Before planting, make sure you buy certified seed potatoes (small potatoes specially for planting) from a nursery or reputable source to ensure they’re virus and disease free.

Make sure your potatoes are covered at all times during the growing process. Any exposure to sunlight can turn them green. Green potatoes are toxic so make sure you throw them out when you are harvesting.
