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. If you are interested, here’s a tutorial on how to grow mushrooms in coffee grounds and cardboard! ?
