My napa cabbage plants are growing nicely, but the leaves are riddled with holes from some little bug. Who's doing the eating, and how can I protect the plants without chemicals?

Cabbage butterflies and other moths can smell cabbages and lay their eggs underneath leaves. They can do a lot of damage.

BT (Bacillus thuringiensis - a brand name is Thuricide) is an organic spray for control of many caterpillars. BT is a natural bacteria that makes the worms quit eating. It doesn't kill the next day, but it is effective.

A row cover is another way to control these butterflies. Agribon is a brand name. Some people buy Tulle (think bridal veil material) and cover the whole bed.

I used both methods this year, and had good success.
