I keep having issues with my beech leaves every year. Any ideas of what may be causing the issue? I have been keeping these in a free draining mix of turface, pine bark, and expanded shale. The leaf margins continue to brown. They start off spring well and progressively get worse through the summer. Is it too much sun, too much or too little water, or the quality of the water, fertilzer? I can't seem to figure it out. I’ve used an in-line water filter that has improved the leaf health of a majority of my deciduous trees. I typically only fertilize with fish fertilizer or Biogold. Also tried to place some in full sun and others in part shade with only morning or late evening sun. Still all seem to develop this leaf issue. Is it fungal? My initial thoughts are soil but not sure.
