I have an Italian cypress tree in my backyard which is about 20 feet tall.
How much water should I give it? Also, how frequently should I water it?
I should point out a big caveat. The tree is dying and starting to turn orange. It might be dead already. The main cause of this is the California drought and my lack of watering it. It's been alive for at least 20 years (without any external water intervention). But now I fear it's dying (or dead) and the lack of rain is accelerating it's death.
