Fungal infection of Andorra compact junipers
Four years ago I planted 35 Andorra compact junipers alongside a 100-foot trench that I had built to convey water from my backyard to a catch basin. The junipers have thrived, some reaching 4 ft high and 6 ft wide. Due to erosion, the junipers have started to fall into the trench, so I trimmed the center branches thinking that this would help re-balance them. Meanwhile, 50 feet away my tomato garden has been increasingly infected by fungus, probably late blight, and this year I got almost nothing from 50 plants before they died. Now, about 2 weeks after I trimmed the junipers, I have noticed for the first time that all of them are turning brown from the ground up. I read in your article that fungus enters junipers from the edges of cut branches. That means I introduced it. What do I do now?
