The message
from Phisherman contains these words:

Bone meal is a good fertilizer for bulbs and tubers such as crocus,
tulips, hyacinth, iris, etc. Apply it after the blooms die.

Better buy it now, if the reports about BSE presence in the USA's
human food chain are accurate. Bonemeal use by gardeners was an early
casualty of BSE in the UK (steam sterilisation doesn't kill the prions).
