Q.Can I use Vermiculite to aerate soil in a raised garden bed?
I have an L shaped raised garden bed where one side is fine but the other section is always damp. It’s about a year old and I had planted Acacia Limelights but they have recently died. I also have a few Leucodendron (Jolly Jokers) that are not happy. I’m not sure if it’s a drainage problem or not. Could I possibly add Vermiculite to the soil to aerate it or would you suggest something else? I really don’t want to have replace the soil! Thank you, Barbara.

Usually something like peat moss or compost is added to soil to improve the drainage. The Acacia Limelight needs well-draining soil so that might have been why it succumbed. Make sure you are choosing plants that need part-sun since this is a morning sun situation. Here is an article about amendments to improve drainage:
