Potatoes are great, they’re a nutritional powerhouse and are cheap and easy to grow. Unfortunately since they grow underneath the dirt, they’re more negatively impacted by pesticides, so buying organic or growing your own is a much better way to go health-wise.

Depending on the variety of potatoes, it will take about 60-120 days before they’re ready to be dug up and harvested. So when should you plant potatoes?

Best Month & Temperature

So the best month to grow potatoes depends on where you live. Potatoes would not grow if it’s too cold, the soil temperature should be no less than 7 degrees celcius (45 degrees Fahrenheit). I live in BC, Canada where this is usually around early spring, around Early March, then it doesn’t get below 7 degrees C until late November. So where I live, there’s a good 8 month window every year to plant these spuds. 

Quick Tip: Optimal soil conditions would be moist but not overly watery.

How To Plant Potatoes

  1. Take large or medium sized potatoes, cut them up into quarter chunks that are at least 2 inches in diameter. The small bite-sized potatoes you can just plant them in whole.
  2. Dig a hole about 6 inches deep in the dirt, plant the potatoes with the cut side facing downwards, and the “eyes” (where the sprout comes up) facing up.
  3. Plant them in a row, spaced at least 12 inches apart
  4. You don’t have to water them everyday. But they do need at least 1 or 2 inches of rain every week. So no need to water them if it’s raining a lot, but start watering them if it gets too hot and dry.

Harvesting Your Potatoes

Gently reach your hands into the dirt, find the biggest potatoes and pull out those ones first, leave in the smaller ones so they can keep growing. You can either eat them in the same day or store them in a cool and dark place. Generally speaking potatoes store really well, some varieties such as Russets and Carola have been known to be able to store for months without going bad.

  1. This is a very timely blog for me, my wife is in the nursery as I write this buying seed potatoes. My plan is to plant them in a straw stack, I’ve not done this before so have a learning curve. Our frost is most likely over for this winter, I live in Northern California, and the overnight temperatures are above 45 degrees F, I may be a touch early, but I’m impatient. Very good article, thanks for posting it!
