Something eating our Penny Royal mint
We have Penny Royal as a ground cover. Until recently it was doing
incredibly well. A few months ago we noticed one of the plants had been stripped entirely of it's leaves. For a while after that nothing more happened. Recently whatever it was returned and went a little crazy. Most of the plants are now stripped to their stalks. We've spent hours looking over the plants for possible culprits but have found nothing that explains it. A single caterpillar here, or beetle there but nothing in the kind of numbers I'd expect to do this kind of damage so quickly. I started looking on the net for answers. It seems that Penny Royal is a popular pest repellent which leaves me further perplexed. If it's so good at repelling insects what could possibly be eating it? Assuming we can identify it the next question is what can we do to control it? We're against anything that might negatively affect the local insect, plant or animal life. And we're even happy to cede a percentage of the plants to whatever it is. But this total devastation is hard to accept. Anyone got any ideas? James |

James You didn't mention where you were, but what about deer, woodchucks or other herbivores? Even if it's not part of their normal diet, animals are known to discover new things, or self-medicate. |

I think you should start looking over the neighborhood and not the plant.
Does this only happen when you aren't home or at night? Do you have anyone near by making sachets? Start sniffing your neighbor's breath for the scent of penny royal tea, usually what the leaves are used for. I'd set up surveillance, park your car around the block, tuck some branches in your hat and be vewwy, vewwy qwiet Val wrote in message oups.com... We have Penny Royal as a ground cover.

We had exactly the same problem. No idea.
I recommend going out at night with a torch. I'll bet you find dozens of caterpillars on the mint. We spent a few night going out and picking them off and our mint is slowly recovering. I still don't know what species of caterpillar they are, I found the same perplexing pest-repellant info on the web too. James |
