Adding soil to container

Question

My plant is doing well in sand, but have trouble when watering with keeping sand in place. Can I add soil on top of the sand to steady my plant when I water it?

Answer 1

I don't see why not. It will eventually work its way down. To improve its fertility and composition you can add compost or rotted manure instead of soil.
