Organic material is the only thing that will do it. It holds water like a bath sponge. Add as much compost, finely shredded bark or well rotted farm yard manure as you can get.If you can get used mushroom compost from a mushroom farm, that is good, but it contains lime so don't use it on acid lovers such as azaleaa or rhododendrons. Adding sand or grit is useless, it just makes concrete.
