40'F is pretty good at hindering mold & bacteria normal growth rates. Water change 1-3 days. Optional concentrate lemon juice to acidulate the water is a wonderful preservative. I do a similar thing for celery stalks, bok choy, lettuce heads, baby carrots, etc -- but not asparagus.
Areas of ambient high humidity would be factor for increased bacteria rates also. A water tray may not even be necessary. Dry climates will benefit more.

I was going to razz you for making up 'acidulate', but I looked it up and it's a real word. You win this round, Vick.
