From Carol Eichler, chair:
Evaluate a new plant; what is its growing habit? will it be invasive?
Provide extra attention for an ailing plant
Serve as a placeholder until a more permanent spot can be prepared
Propagate cuttings or divisions (for our plant sales)
Tend young seedlings
Hold divisions until our plant sales
Overwinter late acquisitions
Carol recommends it.
OK, I lied. I only came up with 8, but maybe someone else can suggest some other reasons to make it 10.
