Help with Italian cypress trees

[BlakeW83]

I live in Houston area and about 3 mo the ago I bought and planted 4 12’ Italian cypress trees to replace 2 30’ ones that died in front of my house. One of the new ones started looking rough and I chalked it up to newly planted. Well it went down fast and made me panic. I treated all 4 with Bayer insect disease and mite control and then with a fungicide. The main tree in question is still green on bottom. It looks thin because I did remove some of the dead limbs. Worried whatever it has the one to the right of it is getting because it is showing signs of browning. Looking for advice on how to save them and accurately diagnose the problem? I’m not over watering.

12' is a big tree to transplant, there is only a certain success rate.

Bid odd to plant trees that can potentially grow over 100ft that close to a house anyway.....?

 

 

The Foilage is s likely become ugly & bare on the house side due to no light from that side  & look at how the two better ones  have  started too lean out away from the wall  for the light already....will cause issues in future...

 

 

Id suggest get rid of  the brown one and  also consider planting something else more sensible, shrubs ot climbers up the wall perhaps...

 

 

 

When one particular species dies in a location its often  wise not  to replant the same again as its likely the site did not suit the plant.
