Grow Bag Potatoes in 5 Easy Steps

Potatoes are some of the easiest and most fun veggies you can grow in your garden. They don’t require much attention, there are tons of varieties you can’t find in the grocery store, and it’s a super fun treasure hunt come harvest time. Did you know you can grow them in bags?! Awesome for gardeners with small space or poor soil. Check out my 5 easy steps for growing potatoes in grow bags below. 

STEP 1

Get a 7-10 gallon grow bag and roll the sides down 2-3 times. 

STEP 2

Put 4-6” of potting soil in your bag. 

STEP 3

Place 3-5 chitted (or sprouted) potatoes on the soil with their sprouts pointed upwards. How many potatoes you use will depend on how wide your bag is. 

This grow bag wasn’t as wide as some others I had, so I used 4 seed potatoes instead of 5. I left a few inches of space between each potato.

STEP 4 

Cover potatoes with 2-4” of soil. 

STEP 5

Water deeply until you see water coming out the bottom. 

And don’t forget to pop your label in your bag so you know which variety you planted! This comes in handy for seed potatoes you can order. Make sure to place your grow bags in full sun (6-8+ hours of direct sunlight).

Once your vegetation grows about 6”, unroll your bag once and fill it with more soil, leaving only a bit of foliage exposed. Potatoes are tubers, so they develop along the stem as the plant keeps growing vertically! They’ll be ready to harvest once your foliage yellows and starts to die off. Then it’s a fun treasure hunt for the fam. 

Pro tip: dump out your bag of potatoes at the end of the season into a wheelbarrow for easy clean up! 

Check out my potato harvest from one grow bag last year. These varieties were Australian Crescent (yellow) and French Fingerling (pink). 

And did you know purple potatoes could look so pretty?
