The message

these words:
Washing-up liquid is not soap.

But it does the trick.

You do have to be careful what you use it on. Some plants do not
like this treatment. I defoliated a bay tree once this way. It
stripped the surface waxy coating and the leaves desiccated within
a few days of application.


... This is why I suggested using only a drop.


A drop in how much water? 1 cc? 1 litre? 100 litres?


In the amount of water you'd expect to put in whatever container came to
hand if you were planning to anoint a few rose bushes with it. That
might be one litre, or it might be a washing-up-bowl-full.

I made the (I think not unreasonable) assumption that John is an amateur
gardener, and owns an ounce of common sense, and a bucket.

I suggested in my previous post that simply giving them a good wash with
a hosepipe would be my preferred option.

Incidentally, I've found commercial pre-mixed insecticides damage some
plants too. I have a Streptocarpus that hates everything I have tried:
any recommendations for this would be welcome.
