A question I see a lot from people who container garden is what to do with the soil from last year that is in their containers. Do they get rid of it? Reuse it? What? It seems like every year once we get close to growing season that this question comes up.
There are a lot of options. If you have a compost pile, you can dump all of the old soil that doesn't have plants currently growing in it, bulbs that will come back each year, etc. This gives it a chance to be reinvigorated by the nutrients it picks up from your compost heap. But what if you don't have a compost heap?
