Arid natives: 25% topsoil to 75% parts drainage materials; most succulents
Tropical natives: 50% parts topsoil to 50% parts drainage materials; Jungle cacti, Kalanchoes, Euphorbia
Lithops and other sensitive plants: 10% part topsoil to 90% drainage materials
And yes, other plants will love it too! Bonsai, Herbs, Azaleas, Hibiscus and just about any plant that likes their soil to be airy and fast-drying around their roots.
You can add more topsoil to your mix if you live in an arid climate or grow indoors. In humid climates, reduce the topsoil and add more drainage materials. You can also use potting soil, but be sure it doesn’t have additional fertilizer.
