Finally we have a real solution that is effective in treating pseudomonas! My wife has developed a horticultural tea that stops an active outbreak and it clears up the vascular system. We have been using this trearment for the past few seasons on several varieties of Japanese maples and have found it works on fungal infections too. Read below for more on the story or check out the pictures as they speak for themselves. A few seasons ago we had the worst Winter in history. We had several weeks below 0F and a 72 hour period that was -25F. We were about to lose much of our collection of large specimen Japanese maples. The first to go were a large Sango kaku and Amber ghost in March. The bacteria started as small areas of black in the trunk that would double in size in just hours and the trees were completely consumed in just a few days. they were all black and the once healthy looking buds were black and the trees were dead. A week later I walked around the garden to see that Orange Dream, Mikawa yatsubusa, and Corallinum were doomed and will be the next to go. Mikawa and Corallinum 50% consumed with Corallinum had black all the way around the graft. My wife asked if she could treat the trees with some of her plant based herbal remedies, and I figured they are going to die anyways so what do we have to loose. My wife brewed a tea and treated the trees by spraying topically and watering into the roots systemically. The black in the bark stopped spreading, so I knew we were onto something. So then we tried a combination of antibacterial and antiseptic ingredients and we re-applied a few days later and the black turned grey. Using the new solution we treated new outbreaks and found that the black turned grey in just a day, we re-treated in a few days and again in 10 days. The bacteria was in remission and the trees started leafing out late and slowly. I choose remission, because some trees had future outbreaks, but all were controlled that Spring and many of the trees performed very well that Summer and fall. Kagari nishiki was the latest to leaf out in July. To add insult to injury, the next winter we had the coldest February in history. Fast forward 3 seasons and now we have perfected the tea and it treats bacteria and also fungal leaf diseases. We also found that it treats clematis wilt too. We feel it is a real breakthrough. Now we have a sense of control and confidence when treating pseudomonas as we have a solution that actually treats and controls an active infection. It has saved 50% of our collection. It also seems to clear up the vascular system as these trees stand up to full sun and 90f+ heat. Most trees could not survive the summer with over 50% of the tree affected by a bacterium. Here is the tree that was hit the worst, Corallinum. Mr Shep told me if you can treat a bacterial infection in the graft that we were really on to something as a graft infection is the hardest infection to treat. When you see the pictures you will wonder how this tree is alive and how is it back budding through dead tissue. First spring after treatment, the black active spreading infection stopped and turned grey: 2015 Grey is starting to flake away showing a light brown.
