Potting soil gets thrown out way too often! Barring a few serious issues (soil-borne pests or disease), you can and should re-use and revitalize potting soil for use in your container gardens. The simplest way is to add back 1/3rd fresh potting soil or compost, but the EPIC way is to tackle it in 4 steps:
1. Clean out any large roots, screen for grubs, etc.
2. Add some fresh compost or potting mix
3. Add slow-release organic fertilizer
4. Add worm castings for microbial life, worm eggs, and more nutrients
