Arizona cypress trees are extremely drought tolerant and grow fast even in harsh climates. These low maintenance evergreens range from blue to gold. Always prune cypress trees in the fall when they are most dormant to ensure you'll see new growth and buds in the spring. There are a couple of things to keep in mind when pruning Arizona cypress trees.
Put on the gardening gloves to protect your hands and skin.
Removing any diseased branches back to the trunk. This is done to decrease the amount of branches the tree needs to feed by removing the weaker ones and leaving the stronger ones. It also increases sun exposure and circulation to the interior of the tree, and gets rid of any diseased or dead branches.
Use the pruning shears to cut no more than 1/3 of healthy branches down to where they meet the tree trunk.
Use hand shears to tailor the appearance of the cypress, especially if your cypress is shaped as a hedge or topiary. Skim along the surface to form the cypress as you wish in a desired shape or just trimmed neatly.
Pinch the stem tips with the pruning scissors as the final step of pruning the cypress. This means you are removing the stem tips to promote branching and new growth.This helps keep your pruning in check so you do not have a lot of work to do each fall.
Dispose of the sheared of branches, leaves and tips.
