Cypress trees can be affected by fungal diseases such as Cypress canker, which can lead to their death. Cypress canker is a result of a fungus called Seiriduim Cardinale. This fungal disease can affect various cypress tree species like Monterey and Leyland.

The main symptoms of cypress canker include sunken patches, cracking, resin bleeding, and dark patches. If the trunk gets infected by the cypress canker, it leads to the death of the whole tree.

2. Poor Drainage

If your soil is waterlogged, it can lead to the rot of the root system of your cypress tree, which is caused by fungal pathogens. These pathogens cause the root system to decay, making the root system stop absorbing water and nutrients, thus leading to the death of the plant.

3. Pests

Cypress trees can be affected by various pests, such as tip moths and cypress bark beetles, among others. These pests usually attach the foliage and the tree bark, thus weakening the plant.

4. Harmful Chemicals

Cypress trees can also die when exposed to harmful chemicals like herbicides, pesticides, fungicides, and industrial pollutants. These chemicals affect the health of your cypress trees, which leads to their death.

5. Extreme Temperatures

Although cypress trees can withstand harsh climatic conditions like extreme temperatures, they also have their limits when it comes to temperature tolerance. Frost or low temperatures can damage the branches and foliage of your cypress tree, leading to their death.

6. Drought

Cypress trees can suffer from drought if they don’t receive enough water, leading to dehydration. This weakens the health of your plant, causing it to die. To prevent this, water your cypress tree adequately during drought or add mulching to retain soil moisture.

7. Human Activities

Human-related activities like improper pruning, construction, and soil compaction can damage your cypress tree, leading to its death.

8. Bad Growing Conditions

Planting your cypress tree in bad conditions, like inadequate sunlight or poor soil drainage, can lead to its demise.

9. Old Age
