That depends on the tree. However, Nevada has a fairly “flexible” trimming season. We inspect every tree before trimming it to make sure it can handle either the heat of the summer or the cooler temperatures of winter. It’s best to discuss this question with our estimators and they can provide more information based on the condition and health of the tree. There are also trees in Nevada, Palm trees for example, that are best trimmed when the seed pods start to come out. So, ask our estimators and they can give you an idea when is the best time to trim your particular trees.
