Regrow Used Veggies In Water, Don’t Throw Them Out

Did you know that you can regrow a whole range of veggies after using them using only water? Here is a full list of veggies which can be easily regrown and used over and over again using only some water and a sunny spot on the window sill. This is great for those who buy a lot of organic vegetables and is a simple water to stretch your grocery budget a little further.

Just to be clear, this list is only those vegetables which can be re-grown to the point where they can be used again purely in water. There are plenty of plants which can be started in water and then transplanted into soil but unless the vegetable can be re-grown into something that is again usable in only water, they didn’t make it onto this list.

Here is the full list of veggies which can be re-grown:

  • Cabbage – Place the root end in a shallow bowl of water.
  • Carrot Greens – Place cutoff carrot tops in a shallow dish of water.
  • Celery – Cut the bottom 5cm (2″) off the stalk to regrow.
  • Fennel – Cut the bottom 3cm (1″) off the stalk.
  • Green Onion – Place the white bulb in water.
  • Leeks – Cut the bottom 5cm (2″) off the stalk.
  • Lemongrass
  • Lettuce
  • Basil
  • Beet Greens
  • Coriander/Cilantro
  • Ginger
  • Mint
  • Mushrooms – The undamaged stalks can be re-grown.
  • Pineapple
  • Potatoes – The middle section of any unpeeled potato will regrow.
  • Rosemary

Some General Tips

  • Don’t use too much water. The water only needs to cover the roots of the vegetable otherwise the leaves and stems will go slimy. Remove any leaves which wilt and land up in the water as these will also cause the water to go slimy.
  • You can regrow multiple plants in the same container as long as they are not squashed together. For example, two to three lemongrass stalks will grow in one glass.
  • Lettuce and celery should be grown in shallow bowls while green onions and lemongrass can be grown in taller glasses.
  • You can add a tiny amount of liquid fertilizer to the water to encourage vegetable growth.
