I have a couple of small, colorful, striped gourds that I purchased at the
supermarket. I use them for still-life arrangements, and I would like to
prevent any mold growth while they are drying.

I have read that they should be kept in a dry, warm area with good air
circulation, and sponged with a dilute bleach solution. But I could find
no details on how dilute, or how often to do this.

What do you suggest? What has worked for you?
