I reuse potting soil all the time for house plants with no ill effects. I've
never tried it with food crops, though. Is kale a heavy feeder? If not, it
may work fine, especially if you are giving them plant food.

Last year I grew about fifteen Lacinato or
Dinosaur kale plants in 16" pots and had a good
crop.
I'm preparing to plant again and wondering if some
of the old soil could be re-used this year with
the new potting soil. Has anyone tried this before?
