Neem Oil on Hostas?

Ottawa, ON(Zone 5a)

Has anyone used Neem oil on their hostas?

I heard a talk about Dahlias last evening and the speaker was extolling the virtues of Neem oil for controlling earwigs and slugs among other things. Has anyone tried it on their hostas?

I used Neem oil on some bananas last year and they were fine and the bugs weren't. I think it said not to cover leaves with Neem and then expose to hot sun. I really like the stuff!

Hi Ann,

I used neem on my hostas. Just be careful to dillute it in water and don't apply it on a sunny day. One of my hostas' leaves crinkled up after I applied it, I think because the sun hit it before it dried. It never fully recovered that season.

Hi Tracey
I believe that my Neem oil had a dilution recomendation with warm water and maybe one other thing. The bottle was obtained at Revy in Canada and was 10.00 for 100ml's. I misted it on in the recomended strength and Yes I did not have them in the sun.
