Moisture is the Life Blood of Trees
Trees, plants, and shrubs cannot exist without water. They depend on water for growth and survival. This is why you don’t see prosperous trees filled with green leaves growing in the desert.
If planted in place with little precipitation or drought like conditions, there needs to be an irrigation system setup so that they can absorb water and use it as nutrients.
Believe it or not, the relationship between water and trees is cyclical. When water falls, it’s absorbed by trees. They often absorb much more than they can use and end up humidifying the air. In areas that are densely populated by trees, you will often see plenty of rain.
