Yes that seems to be the best way to handle N.Rustica..-I ain't a fan of N.Rustica but the two variants of N.Rustica that I have like best is "cornplanter" and "Rustica Bolsunov".This summer is the first that I don't growing N.Rustica at all and I most say that I really missing the yellow flowers in my garden..Wow, 60 days after topping... my yellow type rusticas would be color cured, sun dried and naturally kilned on the plant!

It HAS to be Dawn. Other brands don't seem to kill 'em. I put Garlic juice in my spray. Then they all dive off the leaves and into my pool. Had to get a fine mesh scoop to get them out.
I was able to knock out the aphids by adding another couple drops of soap and garlic to the mix. I spray them in the evening, wait an hour, then hose off the plants so I don't build up too much detergent residue.It HAS to be Dawn. Other brands don't seem to kill 'em.

With all the rain we've had, I haven't felt the need to rinse. Of course, that means not a whole lot of sun to fry the little buggers.Since soapy water kills aphids by dissolving their waxy coating, allowing them to desiccate in the sun, I would suggest spraying in the evening (to avoid scalding the leaves), then rinsing, if you must, the following evening.
You're not kidding. I spend 2 day away from the garden and they decimated a large tomato vine.More evidence of Hornwormnado in Vermont! Yikes!
I topped them at 4' or shorter when the flower stalk started shooting up.. This stubby one was only 18". The ones that I didn't top are ~5.5' including the seed head.My Olson is about 5-6' tall now, did yours remain stubby?
