thanks for the instructions.
Then, do you plant them in pots or in the ground?
I use large clay pots with cow manure and potting soil. Add some limestone gravel and put a two inch layer of gravel in the bottom of the ‘large’ pot before adding soil mix and celery sprout. You will be amazed at how much root structure a healthy celery stalk generates. These roots once the stalk is cut off make excellent mulch for the potting soil.
