Celery is one of those veggies that always seems to get wasted in our house. You use the 2-4 stalks a recipe calls for and then it sits in the veggie bin for the next month until we finally compost it. Instead of tossing it, try planting it. That way you can harvest the stalks as needed without having to buy the whole plant every time.
Using a sharp knife, cut the stalks off the plant leaving two to three inches above the base. Use the stalks for a tasty recipe.
Place the base root/flat side down in a shallow dish of water and place near a sunny window.
Note: Outside stalks will wither and brown, this is normal!
Change the water every few days for one to two weeks. At this point you should have green leaves sprouting from the center of the base.
Plant in a pot or garden bed burying the entire base and just leaving the new green leaves exposed above the soil.
Water regularly and harvest from the outside, in as needed!
