Regrowing Bok Choy Plants in Water

Growing bok choy from a stalk is easy. Chop off the base of the bok choy, much like you would slice the base of a bunch of celery.

Place the bok choy in a bowl or saucer of warm water, with the cut side facing up. Set the bowl on a windowsill or another sunny location.

Change the water every day or two. It’s also a good idea to occasionally mist the center of the plant to keep it well-hydrated.

Keep an eye on the bok choy for about a week. You should notice gradual changes after a couple of days, and in time, the outside of the bok choy will deteriorate and turn yellow. Eventually, the center begins to grow, gradually turning from pale green to darker green.

Transfer the bok choy to a pot filled with potting mix after seven to 10 days, or when the center displays leafy new growth. Plant the bok choy so it’s almost completely buried, with only the tips of the new green leaves pointing up. (By the way, any container will work as long as it has a good drainage hole.)

Water the bok choy generously after planting. Thereafter, keep the potting soil moist but not drenched.

Your new bok choy plant should be large enough to use in two to three months, or maybe a little longer. At this point, use the entire plant or carefully remove the outer part of the bok choy so the inner plant can continue to grow.

That’s all there is to regrowing bok choy in water!
