Hello Janet and Steven,
Just wanted you to know that something you answered in a musing way during a pruning talk I attended, was right on. You'd said you use bleach and water to sterilize your pruning saw or clippers. Someone asked if they could just use antiseptic wipes on their blade between cuts of a plant suspected of harboring disease. I think the plants being discussed were a cherry with black knot and euonymus with crown gall. You said, "Probably you could, but not just a simple wipe. It's probably like at the blood bank, when the nurse has to rub the skin with alcohol for x amount of time."
I just ran across a Cornell University bulletin that prescribes a minutes-long soak in 70% alcohol or 10% bleach. Doesn't seem like a swipe with an antibacterial tissue can approach that!
Thank you. That's great information.
