Potatoes are one of the easiest things to grow in your permaculture garden. If you do it right, it's almost zero maintenance and a pure gift from nature. We plant potatoes each year, and the potatoes are getting bigger and better with each passing year!
We sow potato seed in the first week of October, when the maximum temperature is still high, but the minimum has started to fall. The seed is typically small potatoes which have started to form green shoots with the changing weather.

Conventional farmers make mounds of earth to bury the potato seed under each season, which is more time consuming and can be displaced by heavy rainfall. We used to do the same in the past, planting potatoes in mounds, but now we plant potatoes in Raised Beds. At Aanandaa, all our beds are permanent, saving the effort of making beds each year, and keeping the soil undisturbed, fertile and productive.
Since the soil in our beds is already soft and aerated, we just make a groove in the bed and bury the potato seed about 12 inches apart, cover with soil, and add wood chip mulch on top, which keeps the soil moist and weeds away. 

We also add Jeevamrut, a liquid fertiliser made from cow dung and urine, every 15-20 days.

At 3 months, exactly 90 days, the potatoes are ready for harvest. You can tell they are ready when the plant starts turning yellow and wilting. Potatoes should not be exposed to light, as they turn green and toxic, so it's important they remain covered with soil throughout the crop cycle.
