FAQ: Can you regrow any vegetables from scraps?

regrowing carrots, green onions aka scallions, cabbage, and beets in water

People often ask: “Can you regrow everything from kitchen scraps?” The answer is no. For example, you cannot regrow cauliflower or broccoli from scraps because they are basically flower heads which would not send out roots.

Most of the vegetables and herbs that regrow easily have some roots at the base, or they are healthy stem cuttings that tend to root easily. Like shown in this lovely example by Simple Bites.

Some roots or stems such as cilantro or mushrooms do not regrow either, because cilantro stems do not propagate easily unless there are roots attached at the bottom. And mushrooms grow from spawns.

  1. Will all of these work at any time of year or is there a time that is best? I live in the UK so there’s a significant difference in light between summer and winter.

    Thanks for the great inspiration!

  2. I have grown sweet potato in the past and have avocado growing right now but I have never tried any thing else like you have shown. Thank you so much, I can’t wait to get started. I got a late start on my gardening because of the corona virus. I could not believe that I could not find plants or seeds in my area by the time I went to look for them. Most every thing was out of stock! There was a run on plants and seeds, who would have thought!
    Because of health reasons I haven’t been able to get out to garden and this was to be my first year able to. I have been so bummed for weeks but this sounds like so much fun. Again, thank you, I am happy I came across this. You have made my year!!!

  3. How do I keep gnats away from the plants and prevent mold or grime from growing on the roots? I live in AZ so it’s pretty hot here. If I don’t have a legit window sill can you offer a suggestion?

    • hi Charli, if the plants are healthy and rooted, the water will stay clear with no mold or smell! keep everything out of direct sun unless they are growing in soil. a bright spot will work,, for example a shelf by a window. πŸ™‚

  4. Do you use the green shoots that come up from replanted onions for anything while growing? Can they be used like a green onion for example or does the plant need them to continue growing? I replanted several onion scraps earlier this year and they all have long green β€œleaves” for lack of a better term that are just waiting to be eaten!

  5. Why offer a way to Pin this article then send a complaint to Pinterest so they remove my pin? Something about a digital copyright act??? This is a blog about gardening. Completely Ridiculous

  6. Wow!
    Great ideas to grow your own vegetables.
    I grow some Vegetables in my Backyard Garden and grow chick peas in water.
    Thanks for sharing the more useful ideas to grow herbs and more.

  7. I understand that these vegetables can be rooted and start to regrow in water. Do all the ones you discussed above reproduce the full vegetable? Do some only reproduce the greens if kept in the water but will fully mature if put into soil? Thank you.

    • hi tracy! the onions and greens can grow to full veggies if planted in soil, but beets and carrots will grow tops, and can produce seeds for future planting if planted in soil. πŸ™‚

  8. Thank you so much! I didn’t know I could grow back so many kinds of vegetables and herd from scraps, gotta try it next time, start with celery and scallions.
