Q.Have A Hibiscus Plant And Sprayed With With Immunox Multi Purpose Fungicide, Leaves Turned Yellow, I Guess Not Good For This Plant
. I have 5 different hibiscus plant and bought this for hydrangea plants and used it on my hibiscus plants. It caused one of the hibiscus plants leaves to turn yellow and then die off. just part of the plant. I assume I should not use this on my hibiscus. I believe it will be alright as we are at the end of out season and it is still blooming beautiful flowers.

I shouldn't kill it. It may be that there was an issue, and that after the fungicide killed the issue it may have taken a portion of the plant with it. It is best to spray a small portion to check sensitivity before spraying the entire plant to avoid potential damage.
