How can I save my arborvitae from dying?

To save your arborvitae from dying, make sure it is planted in well-draining soil, receives adequate water, sunlight, and nutrients, and is protected from harsh weather conditions and pests. Prune any dead or diseased branches, and consider applying a balanced fertilizer to promote growth and health. Regularly monitor the tree for any signs of distress and address any issues promptly.
