I have a small container garden (https://vegepod.com.au/collections/raised-garden-beds/products/raised-garden-bed-small) which I used to grow some bok-choy and silverbeet about 18 months ago.
The soil that I used is a combination of premium potting mix, and some cow manure.
Since moving about a year ago the container garden has been sitting on my balcony, and has not been used to grow anything since the move.
I'm looking at planting some new vegetables, and I am wondering if it will be safe/effective to reuse the soil, or whether I should replace the soil?
