I have been into bonsai for about 7 years now, and have acquired some very nice trees with a lot of potential. I’m losing many of them and am having no luck at turning the tide. In February of 2020 we moved from Portland OR to Charlotte NC and I brought about 80 trees with me. The year in NC I barely worked any of my trees as health after the move was my focus. They met extreme humidity in Charlotte with all new fungal, insect, and disease issues for me, as well as wind that both desiccated leaves and ripped apart my benches at one point using a large tied down elm as a wind sail. A tough year to say the least, but most survived. In June we moved back to OR but now in the high desert in Bend. Now they are experiencing extreme heat and dryness. Two weeks ago we had to say goodbye to our dog (Biff has always been my profile pic here). His last week with us coincided with the record breaking heat wave, and although I watered as usual, my dog and my family needed my extra attention. The last two weeks have been a huge decline in health for so many of my trees. While I expect to be able to save some still, the damage done to almost every tree will set me back years. This loss on top of our dog is rather devastating to me. With such a crazy year and a half for the trees it’s hard for me to pinpoint one problem, as they don’t seem to be presenting the same way. Here are assorted pics of pines, some with yellowing tips, some with browning tips, some where massive sections of needles just turned dark brown, some where they dried right up in the heat. The pics include lodgepole, JBP, mugo, and white pine. I have been alternately spraying my whole collection with mancozeb and clearys 3336 but that doesn’t seem to be making a difference. Any help on how to get in front of this is greatly appreciated. This will be a big test in my resolve for this hobby, but I love it too much to let go.
