Grow Garlic In Water Bottle

Here’s how to grow your own garlic for pennies:

  • Clean a 2-liter water bottle and cut off the top, about two inches from the top of the bottle.
  • Fill the bottom of the 2-liter water bottle with soil or potting mix and plant one clove inside, then cover it up with more soil and water well so it’s good and moist.
  • Place the water bottle in a sunny spot where you can access it regularly to keep it watered.
  • After two to three weeks, you’ll see a water bottle full of garlic.

There are a few limitations of growing garlic in water bottle.

  • Grow garlic in the spring, when there are many more flowers and more food will be available (i.e., more pollinators) for the garlic to use. If you wait a few months after planting until the first summer heat, it may not produce as much as it was germinating, before getting hit with the summer heat spikes. If you wait until the spring, then you’ll have to endure a couple of months of cold weather before it’s ready to harvest.
  • Garlic is actually less productive when it’s cold, which can also be a limiting factor in its scalability for large-scale use.
  • Starting in spring or summer may be more common, but if you want to grow garlic in the winter, then you may have to start the seeds indoors and germination will take longer.
  • You’ll need a large amount of garlic to make it worth the time it takes to grow.
  • Make sure to cover the bottle with a cloth or something that allows air to pass through.
  • This is long-term growth, so you’ll probably want to store it inside in an unheated room for the winter months, and then bring it out when it’s time to harvest.
  • It’s a space hog, so you need a place where it can sprawl without knocking things over.
  • Seeds are very small and light—so it could blow away. I would recommend planting in between rocks or something like that to keep it from blowing away from its pot.
  • Depending on the kind of garlic you plant, you may need some kind of weeds removed from your compost pile or soil. Some kinds are more prone to weed growth than others, but if they’re composted well enough, then they would’ve killed all the seeds from any weeds previously growing there and not allowed them to survive into the next season.
  • There’s a variable amount of time between harvesting and it dying. Depending on what the ambient temperature is, how you store it, how long you keep it in one spot, etc., the garlic might die before you can use it. If this happens to you, then you can either let some of it die (I would recommend just composting it), or try leaving it out more than 24 hours to see if a few more sprouts pop up.
  • The bigger the clove, the higher chance of success it will have. So instead of cutting the garlic off a small plant in your garden, just start them yourself from the seed inside so they get as big as possible if you want to grow a lot.
  • If you germinate indoors, note that seeds can take up to a year to sprout. I would suggest starting them in the fall with a little bit of soil and light, then cover them up out of the winter where they’ll have some sunlight in your garage or some other indoor spot where they can grow.

The Best Types of Water Bottles to Grow Garlic

There’s a lot of different types of bottles out there, but according to one source online, the following are the best kinds of water bottles to grow garlic in:

  • 1-gallon spring water bottles (preferably made with recycled plastic)
  • 2-liter soda and mineral water bottles (plastic or glass)
  • 2-liter soft drink bottles (plastic or glass)
  • Bottles that are at least 20 cm / 8 inches wide and 23 cm / 9 inches tall.
  • The type of plastic should be clear so you can see how much moisture is in the bottle.
  • There should be something to hold the water in the bottle so you can put your hand over it to keep it moist. I would recommend using a piece of cloth or paper towels, but not something that will weigh down or cause the water from sitting in it.
  • You can use any kind of water, as long as it is bottled and not tap water.
  • Small bottles with a metal screw-on cap are best.
  • A water bottle with an opening around 12 cm / 5 inches will be perfect to fit the garlic inside.

Is Garlic Grown in Water Bottles Safe to Eat?

According to the Centers for Disease Control (CDC), garlic that is contaminated with a pathogenic microorganism will still be safe to eat as long as it has been cooked properly.

The CDC says that “there are four groups of microorganisms usually considered pathogens: bacteria, viruses, parasites, and fungi. Microorganisms that cause foodborne illness are generally referred to as pathogens.

Although most people associate foodborne illness with bacteria, viruses and parasites are also the cause of many foodborne illnesses. Fungi can also cause illness, although they are not normally considered pathogens because they do not cause disease in healthy individuals.

In a few cases, ingestion of certain types of fungi has caused death. Illness associated with the ingestion of fungi is often referred to as mycosis.

Some common pathogens may be present naturally in soil or water and can be carried by animals, people, equipment, or food products.

According to the Food Standards Agency, “For healthy adults, it is unlikely that they would get ill from eating raw garlic. Some people do find raw garlic irritates their stomach and others may experience some mild symptoms such as flatulence; this is due to the hydrocyanic acid content of raw garlic. Cooking garlic reduces the amount of hydrocyanic acid.

Although outbreaks due to raw garlic have not been reported to the FSA, there are some reports of bacteria present in the soil making their way into the bulbs. This has been attributed to poor hygiene when handling and harvesting.”

In Conclusion

Garlic is a very healthy thing to grow, especially if you want to avoid buying factory farmed garlic from China that’s loaded with pesticides. It’s also a great way for kids to learn about gardening or get involved with (and it’s not hard work!).
