At the end of the growing season last fall, I still had some nice celery in the garden. I picked most of it and froze it, but I noticed that some plants had small sideshoots and I decided to pot four of them up. The two smallest ones rotted out but the two that are left have settled in nicely. The bright green foliage is cheerful, and occasionally I snip off a bit of celery for cooking.
Now that the days are getting a bit longer and the sun a bit brighter, new growth is starting. By the spring, I will have two substantial plants ready for the garden.
