I've been shampooing Penny with Malaseb recently, in a successful attempt to resolve the problem of her licking her paws.
Now, because of the drought - or is it permanent climate change? - we run most of our grey water onto the garden. I began to wonder whether a product that is promoted as an antifungal with potent activity against fungi and yeast might be bad for the garden, so I rang the company and receivedthe answer that it was not good to run this greywater onto a garden. If I understood the reply correctly, it was because some of the constituents in it might last a long time in the soil.
Here's are photos of two ivy geraniums in our garden - both plants are in basically the same position regarding shade, sunlight, soil composition, etc. They are about two metres apart. (I pruned them massively recently.)
Here's the first one, that does NOT get the run-off from the dog bathing.
Here's the one that DOES get the run-off from Malaseb.
