We have a lot of planters, containers, and large pots full of annuals.
Would like to re-use the potting mix. Any input would be most appreciated.

I reuse mine for several years unless it looks like it's starting to
compact. It then goes to the compost pile and I start again. A little
composted cow manure is added each spring when I loosen the soil to plant
the flowers.
