I love my Datura, I only have three, a double purple, a double yellow and a white one. I have a terrible problem with aphids on them. The plants are still quite young, I received them at a Round up, but they have all bloomed, however, the leaves have fallen off the lower part of the plant and they look very leggy. I have been treating them for the aphids with a home made mixture that I got here at Dave's. I don't think it is the mixture, since I use it on other plants that are fine. Is it due to the winter, or are they ill? They just bloomed for me last week, one bloom on each plant. I did not get seed pods though. Any advice would be appreciated :0)
Xeramtheum is exactly right!! I had the problem on my Daturas one year and it worked great. Only problem I experienced is it killed the worms so be careful. If I were to have the problem again, I would lay down newspaper on the ground then pick it up when finished, this should insure my worms would be safe.
Here's a graphic example. On the left is what one of two datura looked like before Sevin. I was on the verge of pulling them up and putting something else in, but it was late in the seaon and said what the heck. On the Right is about a month or so after using Sevin. I dusted the leaves top n bottom and dirt around them. They turned out to be my last Datura of the year and stunning too.
Like Judy said, it is not earthworm friendly so I usually only use it in containers.
Thank you for the pictures and information. When I went shopping I saw a Sevin Dust spray as well as the Sevin dust powder, I didn't buy either as I am a chicken when it comes to putting anythying on my plants, other than my home brews. But your pictures sure have put my mind to rest and now I know I need to get the powder form. Thank you so much for your help :0)
I was just reading along in this forum and bumped into this thread. I had/have/had a datura plant last year, and it looked just like the picture that was posted above...but it wasn't aphids that attacked it. It was spider mites. Will the seven dust kill those guys, too?
