Question
Do you know anything about the disease that is comming up the last few years? From top (of the tree) to bottom the branches are getting brown and die....
Is there anything to do?

Answer
Hi Bartel, I do not grow this plant because of the problems with bugs.  I checked around and this is what I found, not sure if it will help you.

Growing in full sun on various well-drained soils,
Italian Cypress should be planted in a well-prepared
site and watered periodically until well-established.
Italian Cypress should not be pruned. It is very
susceptible to mites and trees are often infested.
Many cultivars are available: 慡tricta?is very
popular; 慔orizontalis?has horizontally-spreading
branches.
Propagation is by cuttings or layering.
Pests
Bagworms are occasionally a problem for Italian
Cypress. Mites are often a problem.
Diseases
Root rot can be a problem for Italian Cypress in
poorly-drained soil. Canker has killed many trees in
California.
