I get a severe telling off
I recently had a long and very interesting conversation with a professional grower. He gave me a severe telling off for some of my growing habits. In particular he told me never to cut off dying leaves. He told me to wait until they were about to fall then twist them off by hand. He told me I must use sterilized equipment for ANY "surgery" performed on plants, as this was a very common way of passing disease from plant to plant.
I left very chastened but grateful. I know I do not bother to do a lot of the things he told me - he also told me to spray more often - and I do lose more plants that I care to, especially smaller ones.
Final report: must do better.
