Last year I grew about fifteen Lacinato or
Dinosaur kale plants in 16" pots and had a good
crop. I ate them regularly 3-4 times/week for
about 9 months.

This year I removed the plants from the pots and
it seems that the roots are only a
fraction the size of the pots - about 6-8"
diameter- suggesting that there are still lots of
nutrients in the old soil.

Last year I bought all the potting soil and now
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?

I now have a batch of 10 - week-old seedlings
ready for transplanting. The previous plants had
no diseases and the only bothersome things were
whitefiles and white butterflies. I live in north
California.

Comments appreciated.
