Hi all, I used a home made spray that included dish-washing liquid last year and also noticed that the leaves on the plants went limp, then yellow, then dried up and fell off. I killed some plants and those that survived this treatment only did so because I luckily missed some of their leaves. I for one will never use DW liquid in a home made spray again, as I suspect that this is what did the damage. Cheers Sue in sunny (but finally cold) SA - waiting eagerly for the spring!
