We have several cryptomeria trees on our property and are used to seeing some browning of of the greenery of these wonderful trees, especially in the winter. However, this year I have noticed that entire branches are turning a bright rust color, almost orange as opposed to the regular greyish-brown. One of our younger cryptomeria that was planted 5 years ago seems to be loosing its lower branches by first fading to dull green and then turning this orange color. Our older trees are also showing some similar issues, along with branches that seem to droop for no obvious reason such as storm damage. Is there any known issue affecting cryptomerias in the region? Is there anything I can do to prevent these wonderful screening trees from dying? (I had sent this question previously, but was not able to attach photographs until now)
