Bulbous Blast from the Past
Though I usually stick to the three-times-as-deep, and three-times-the width-apart rule of thumb for bulb planting, I got a kick out of this retro chart. No idea who King Nitrohumus is, but he looks like a royally good gardener. For a blast-from-the-past bulb narrative, check out the rest of this deeply dated comic book from 1956. It's about creating curb appeal with bulbs in a uniquely retro, keeping-up-with-the Joneses way.
