A friend has parsley worm caterpillars on her parsley but they've eaten up most of her parsley. I have seen where they eat dill and fennel but I don't think she has that nor is there any at our community garden.

We have comfrey, sage, oregano. mint, catnip, lemon balm, basil at the community garden, do they eat any of those? What about flower leaves like zinnias and marigolds?

I have parsley at my home garden which will probably help but if other caterpillars come along, which I hope is the case, what can they be fed if we run out of parsley?
