Many different types of trees grow in Arizona. Many trees thrive and are able to withstand the dry climate and extreme temperatures of the desert southwest as long as they receive adequate water, room to grow, and proper trimming when needed. tree trimming phoenix 

Trees that grow in Arizona come from well-known tree categories such as deciduous trees, pine trees, citrus trees and evergreen trees. Here are a few of the trees that grow in Arizona:

Whitethorn Acacia – This is a deciduous tree that grows in Arizona. It can grow as high as 18 feet tall and be just as wide. It provides a lovely fragrance when it blooms–the flowers bloom into yellow puffballs by the end of the spring season. During the middle of August in the heat of the summer the trees may even bloom again.
Cat-Claw Acacia – This is another deciduous tree that grows in Arizona. It grows very quickly, and can grow as high as 15 feet tall and 20 feet wide. This tree should be watered on a regular basis and requires pruning. The green leaves are very small and have thorns at the end that are curved. Branches that point downward should be pruned on a regular schedule–usually in January and August. This tree also provides a lovely fragrance when the tree blooms during the spring season.
Pine Trees – Though it may surprise some people, several types of evergreen trees grow in Arizona, and not just in the mountain regions. When pine trees are planted, they should be spaced at least ten feet apart-spacing them too close together will more than likely require a tree removal job in the future. They will grow better if they are planted on level ground or near rainwater. Pine trees need to have plenty of water in order for them to grow and thrive.
Citrus Tree – Citrus trees are abundant in southwest Arizona and especially the Phoenix, Arizona valley. In Mesa there are citrus tree orchards that are a few decades old and full of mature trees. If you are considering planting your own citrus trees, the best times are in March, April and October. Although you can plant them at other times of the year, these months will typically give the trees adequate time to become established before the hot weather hits and will provide the best fruit crops.
These are just a sampling of some of the trees that grow in Arizona. For a more complete list of what trees grow in Arizona, consult the International Society of Arboriculture (ISA) Arborist Certification Arizona Tree List. The list contains 46 trees, but keep in mind that the list is not comprehensive and does not contain all of the trees that grow in Arizona.

Trees that grow in Arizona must be able to thrive in different types of weather depending on where they’re located. In the desert southwest the trees will need to be able to withstand the extreme heat during the summer months in order for them to be able to grow and thrive in the landscape of Arizona.
