On the large containers, I go thru the extra trouble of placing a piece of window screen to prevent so much silt/dirt from falling thru the peanuts. Window screen (plastic not metal) is another gardener's friend. It costs about $12 a roll and is excellent for putting over container drain holes to slow down erosion.

Maybe somebody on CL is getting rid of their screens, and then it costs you nothing. Avoid metal mesh as it disintegrates in the pot. The nylon ones are flexible to work with and more durable
