Depends on what type of medium. Orchid media (often bark) breaks down with time and so cannot be used for Orchids again. I do use it on my garden, though.

I use mine outdoors as a mulch. I put it around Heucheras that have started getting leggy. Also rhodies, azaleas, ferns etc.

Mostly the medium consists of Commercial Dutch Garden soil Mix? / some Pearlite/ Promix, and use it grow Eggplants and
Tomatoes.

Yes you can reuse the potting soil. You may want to freshen it up by mixing in some new and also adding water to the soil to make sure the soil is hydrated.

All of my containers get dumped into a wheel barrow in the spring the soil gets sprayed with water and compost added to freshen up the soil before being reused.

Thank you much and would try it.

I just dump my old potting mix into my compost pile and reuse in the garden.

I reuse potting soil all the time. I just add a little slow release fertilizer into it to give the new plants some new food. After a couple of uses I then throw it into one of my beds. They always can use some more soil for some reason.

Yeah main thing is if you don't reuse it for potting soil, don't throw it away. Compost or add to garden.

I add old potting soil to the compost or garden. The soil is pretty depleted by the time I repot and I don't want to transfer bugs or diseases to new plants.
