Awesome job, Eric! Best of luck with your overwintering. I highly suggest you invest in some Neem oil, if you haven't already
Below is a copy/paste that I saved from Pic1. He lives in Chicago, a most excellent grower.
I don't have any issues with aphids on my OW plants. I cut my plants down to the trunk, get rid of all foliage, and uproot them. I use a water hose, and spray all of the soil from the roots, and trim them down to a little ball. I then dunk the plant in a dish soap water mixture, completely submerging the plant for a few minutes. Then I pot up the plant in a 1 gallon pot, fresh soil, and bring it inside.
Now I'm not suggesting you do this by any means. I just want to present the information. Here in the deep south an OW to me is moving them into the garage a few times when it wants to frost 3 or 4 times over the winter. He (Pic1) essentially put them to sleep for the duration of the winter.
Mike's comment regarding Neem is all about bringing them inside, with the passengers
Glad to see the nice pulls Eric!
Mike, Scott, thanks for the info. Yes on the neem. I don't get aphids, but we had a plague of mealy bugs on our bay laurel last winter, I had to about kill it to get rid of the critters.
But if you don't give 'em anything to eat, they don't threaten so much, do they....I'm going to let these plants give up what they will for pods, then cut 'em way back.
