LPT: Store potatoes and onions well apart from each other. They release moisture and gases that can make the other get bad faster.

Also, keep your potatoes in the garage/outside if the weather is favorable. Bagged potatoes are very well know for being cockroach taxis. If the weather isn’t up to par, open the bag outside and remove each potato, inspect them, and place them in a separate bag or container. Can confirm. When I lived in an apartment a few years ago I woke up to one on my kitchen floor. Lost my shit, called my landlady. They had to inspect every single apartment and they confirmed that it was only our apartment that had the issue. They left a trap, then bombed my whole apartment for good measure the next day. Landlady asked if I had recently brought in a bag of potatoes, and I had just two days before I spotted a cockroach in my apartment. I’ve not bought bagged potatoes since. I just buy a few at a time and get more when I need them.

If you’re talking about ethylene, that applies to tons of other stuff such as bananas as well.

I keep my potato’s in the fridge , is this wrong?

TIL. Never store anything next to anything else! Maintain at least 3 feet of separation between all your food items!

i literally have my potatoes next to my onions, fuck.

This LPT is half right. Neither taters nor onions produce ethylene gas. It's the moisture to worry about. Those aren't the only things you don't store next to each other. Keep fruits separate from veggies. Keep leafy greens away from fruits. Store potatoes and apples together. The ethylene from apples keeps the potatoes from sprouting longer. Got unripe stuff? Stash a banana with the unripe stuff in a brown bag. It'll be ready tomorrow morning. Look around for ethylene gas production in fruits/veggies. It'll give you a good idea as to what goes together and what doesn't. Food science is cool.

This applies to a lot of other foods too.

Well TIL. Most potato bins have an onion compartment under the potato area and I use mine. Explains why I can't keep potatoes for long...

For like five fucking years I've been wondering why my big bags of potatoes, that should theoretically be good for over a month in dark storage, have been sprouting within weeks. Same with my onions that decide to grow 2-foot stalks after a couple weeks. Genuinely the best LPT I've seen in all my years on Reddit. Thanks, OP!

I posted this on the post on /r/firstworldanarchists I thought I might as well post it here,it will probably get buried but I think it is kind of relevant. So,I am procrastinating studying so naturally I was fascinated by this... I found many articles saying that storing them together is a bad idea ([1](https://consumerist.com/2014/04/05/keep-your-onions-garlic-separated-and-other-tips-for-storing-fruits-vegetables/) [2](https://www.thekitchn.com/how-can-i-keep-potatoes-from-s-129608) [3](https://althealthworks.com/5961/dont-let-your-potatoes-go-bad-do-these-simple-things-to-keep-them-from-sprouting/)) BUT no source for those assumptions so digging a bit deeper I found [this](http://message.snopes.com/showthread.php?t=9290) forum post from 2007 that links to a university of Minnesota extension service that, allegedly, states the opposite. The link however is dead and someone below comments that the link said that storing them together wouldn't make them spoil but sprout. Naturally no one quoted the link so no dice. The WayBack machine has no snap of the page either so hit a wall there too. After a little more digging I got this[ archived post](https://boards.straightdope.com/sdmb/archive/index.php/t-502667.html) from 2009 that actually has a supposed quote from the page: > There is absolutely no truth to the story that potatoes and onions should not be stored together because one makes the other sprout. The truth is, they have different storage temperature requirements. The optimal storage temperature for potatoes is 40 degrees, the temperature at which onions sprout. Which actually agrees with wikipedia ([Storage of potato](https://en.wikipedia.org/wiki/Potato#Storage) ,[Storage of onion](https://en.wikipedia.org/wiki/Onion)). So is it just that when storing them together most often the temperature is too high for the potatoes and the onions just survive it?That seems unlikely since storing potatoes with fruit does make them sprout even in the fridge.So temperature may be a factor but is it the deciding factor when it comes to storing potatoes with onions? Going deeper [this](https://steamykitchen.com/42764-should-potatoes-be-refrigerated.html) article on potato refrigeration quotes [this](http://www.plantphysiol.org/content/plantphysiol/53/4/658.full.pdf) paper, and uses it to conclude that storing potatoes with onions or any other fruit is ill advised. The paper though is on the correlation between ethylene and potato dormancy and sprout growth. So what produces ethylene (and what is it?) well [wikipedia](https://en.wikipedia.org/wiki/Ethylene) says: > [..]Ethylene is also an important natural plant hormone, and is used in agriculture to force the ripening of fruits. and > [..]Induces root hair growth — increasing the efficiency of water and mineral absorption So it is produced when fruits to ripen but that also induces the sprouting of the potatoes.So that's why storing potatoes with apples and stuff get it to sprout but it will ,in general, make other fruit and vegetables go bad. So do onions produce ethylene? According to[ this](http://www.tis-gdv.de/tis_e/ware/gemuese/zwiebeln/zwiebeln.htm) hazard analysis by the transport information service >The rate of ethylene production [of onions] is very low, being below 0.1 µl/kg*h [16]. and as a bonus > Dry onions exhibit low sensitivity to ethylene, while green onions are moderately sensitive to it [16] (allelopathy). Onions should not as a rule be loaded together with apples or pears. and as for potatoes > Potatoes are moderately sensitive to ethylene [16]. The effect of ethylene is to cause the premature onset of the sprouting process. Thus, products which release large quantities of ethylene (e.g. apples) cause potatoes to sprout prematurely (allelopathy). So to conclude, fruit as it ripens produces ethylene gas that makes other vegetables and fruit sprout and go bad. Some produce is more sensitive to ethylene than others. So in general storing products that emmit allot of ethylene ([apples: > 100 µl/kg*h](http://www.tis-gdv.de/tis_e/ware/obst/apfel/apfel.htm), [pears: 10 - 100 µl/kg*h](http://www.tis-gdv.de/tis_e/ware/obst/birnen/birnen.htm), [bananas: 1 - 10 µl/kg*h](http://www.tis-gdv.de/tis_e/ware/obst/banane/banane.htm)) with any fruit or vegetable is a bad idea. Storing onions with potatoes together is not that bad since they both produce very low amounts off ethylene but add anything else into the mix or let them sit for a very long time and the potatoes will sprout since they are moderately sensitive to ethylene while onions will do just fine.The temperature at which they are stored is of greater importance since room temperature ,while ok for storing the onions, will make potatoes sprout. Also regarding water vapors and moisture I replied to another comment on the same post Onions require a dry, moisture free environment to store as well.What you are referring to is (I think) self-heating. If there is allot of moisture in the environment or there are fluctuations on the temperature or the temperature is really high, the onions will start to expel essential oils and vitamin as water vapor. This however will happen only in an environment unsuitable to store them and that by extension would be an environment unsuitable to store potatoes as well so the point is pretty much moot. These are all conclusions i draw form the link I have above about transport service and I may very well be wrong.

My potato bin sits right on top of my onion bin. Never had a problem in 16 years of storing this way. I grow my own. 400-ish pounds of potato and 100-ish pounds of onion last the entire year. 10 to 12 months. Without issue.

huh? then why are they right next to each other at the grocery store?

Chuck a few apples in with potatoes. No idea how it works but it keeps potatoes fresh for ages.

an onion will keep an avocado good though

Same for avocados and bananas. After Target stores started selling fresh produce, they had to redesign backroom storage to keep them away from each other. I think it is the avocados that make the bananas ripen too quickly. Those avocados, can't trust them as far as you can throw 'em.

Here's a fun game: put a sack of onions and a sack of potatoes next to each other and see which one wins

It seems that this is very poor placement then. https://i.redd.it/vjsqkbjj06g01.jpg
