Introduction: Supermarket Gardening - How to Repurpose Food
Runner Up in the
Did you know there are a lot of vegetables and herbs you can "repurpose" from the supermarket?
This instructable will be about garlic, potatoes, and boiling onions. But you can also do pineapple, celery, lettuce, mango, avocado, lemon, scallions... the list is quite large. Now, do every repurposed edible survive and give a good yield? not always, but it is worth a try.
For your "ingredients" you can choose any of these:
- Boiling onions, red, yellow or white.
- Potatoes, any kind
Step 1: Garlic
The easiest veggie to repurpose!
Buy a head of garlic. You can look for sprouting ones, but it is not necessary. Set them out in indirect sunlight for 2 weeks or so. That starts the sprouting process. Even without any visible green poking out you still can plant them.
Dig a hole in your garden in early Spring or late fall (they can overwinter in your garden). Plant the clove with the pointy end up. Cover completely with dirt. Water. In the 9 years I've been gardening I have yet to find a way to kill garlic with overzealous gardening practices. They are near indestructible, be it from over watering or drought, pests, weeds... you name it and garlic can withstand it.
They need about 6 months in the ground to form a bulb and mature. When the tops yellow out it is time to harvest. Loosen the soil around the plant with a pitch fork, careful not to dig into the bulb. Garlic is hard to dig up, if you just pull on the tops they will break and the bulb will stay nice and snug into the earth. Let them cure for a few days in a dry place.
Bring them in and enjoy your bounty!

Step 2: Onions
One of my favorite cooking ingredients and oh so easy to repurpose.
When at the grocery store in the end of Winter/begining of Spring look at the boiling or pearl onions. Do you see any green poking out of the little onions? if you spot a bag with a couple of sprouting onions, buy it. A supermarket worker looked at me in horror when I purchased 3 bags with "spoiled" onions, onions they would just throw away.
So you have your pearl or boiling onions with little green tips on them. Set them in a plate and leave them in a warm room with indirect light (meaning not in the direct sunlight, that will kill them). Let them sprout for a week or two. Get your garden bed ready with lots of compost. Onions like a well fed, well drained bed. They also like early Spring and can stand some cold.
To plant them just dig a little hole, plop them in with the sprout head up, cover with dirt and water. Keep it moist but not soaked and in a week of so you'll see the leaves poking through!
In the very late Summer or early Fall the onion top will start to yellow. That means it is time to harvest. Pull the onions up and let them "cure" on the garden bed for a week. If it is going to rain that week bring your crop to cure into a dry room. You can braid them or snip the dry tops for storage.

Step 3: Potatos
Who doesn't love young potatoes fresh out of the garden? and if you have not tasted it, then you are missing out big time.
Much like the onions, when you are at the food store look at the potatoes, do any of them seem to be sprouting? if not, don't despair! they just need a little TLC. Even without TLC you'll sometimes open a bag of potatoes and find sprouts on them. Don't throw them out! even if it is the dead of winter and you think you can't possible garden. If there is a will, there is a way.
Set your potatoes (sprout or not) in a plate. Put the plate in a warm room without direct sunlight (they will rot with direct light). Now the magic happens! in the next week, or two... and lets be real sometimes 3 weeks you'll notice little knobs popping out of your potato's "eye". Each knob will be a sprout. You can plant a potato as is or slice it to double your amount of seeds. If you slice them, leave them to dry out for at least 24 hours. Slugs and grubs love fresh cut potatoes.
Once your potato sprouted you can put them in the garden (early Spring is prime time) or you can plant them in interesting things like a ceramic pot, thrash bag, barrel, tire, bale of hay... if it can hold soil (sometimes even without soil!) you can grow potatoes in it.
Potatoes like a slightly acidic soil and not too much water. Whatever you grow your potatoes in, make sure there is good drainage.
Did a whole in your soil (be it in a pot, garden, tire, bucket...) add a healthy sprinkle of Bone meal, wedge your potato in there with the sprout facing up. Cover with soil and water it well this first time. In a drought, water weekly. Now wait...
When the potato plant has flowers it means you can harvest baby boilers, and when the plant turns yellow you can harvest fully mature spuds. Eat fresh or store in a dark spot for future use.
For all things potatoes:
We have a be nice policy.
