It kind of struck me that most of got our start with CPs from the ubiquitous death cube. It also struck me that a lot of different vendors must have used death cubes over the years. And since I remember them in my childhood, they got to been around for probably 40 years old. Many times the instructions on the cubes seems to be conducive to buying more cubes rather than the long term enjoyment of the plant.
So, I'm putting forth the question to the user community. What is the worst (or oddest) horticultural advice you ever received from a death cube? I'll even extend this to any potted CP you bought from a commercial storefront (Home Depot, Lowes, your neighborhood nursery, etc). However, it has to have appeared on a commercially printed packaging or labeling.
My contribution to this question comes a VFT death cube purchased from a Canadian hardware store chain around 1980. The insert recommended that the ideal soil mix was 50% peat, 10% sand, and 40% African Violet Mix.
