Question: My bald cypress tree is constantly yellow. What can I do to correct it?
Answer: If you live in an area with alkaline soil, that’s iron deficiency. It’s especially troublesome when you have shallow, caliche bedrock. In such circumstances, bald cypress really shouldn’t be planted in the first place. However, if you already have an existing tree that is having this struggle, you can always try applying an iron/sulfur soil-acidifier product to see if it helps. It will become quite costly to do so as the tree grows, so be prepared to limit your losses and to replace the tree if necessary.
