Boron

Your name reminded me. After years of using the same soil, it gets depleted.
If you merely replace the major minerals, nitrogen, phosphorous, and
potassium (NPK), some of the other essential minerals may be lacking. That
includes boron, which in excess can kill plants. Other elements,
particularly calcium and magnesium may get depleted at a good rate.

I have a very large container garden. I empty most of the small pots
each spring and about half the soil in the larger tubs. It gets mixed
with compost, peat moss and manure and used in the "real" garden down
below.
