Try throwing spent potting soil, esp. that from seed pots, onto some more-or- less waste area where strays and interlopers won't matter. Bob Woodward and Jim MacPhail used to toss their old seed pot contents on a grassy slope in front of their house, and ended up with a marvelous planting of all sorts of things that decided to germinate once thrown away. Spent soil from pots of geophytes will behave similarly because you invariably miss a few small offsets when repotting. This is called making lemonade from lemons. -- Rodger Whitlock Victoria, British Columbia, Canada Z. 7-8, cool Mediterranean climate
