New Jersey's weather so far this winter has run the gamut: from snowy and icy, to record low temperatures, to highs in the 60s and heavy, deluging rain.

These weather extremes can take their toll on trees in the Garden State, and experts are hoping their advice to residents takes root.

Deciduous trees, which seasonally grow and lose their leaves, are less affected by weather than evergreens. But Steve Chisholm with Aspen Tree Experts in Jackson said there are other threats.

"Obviously, wind storms do a lot of damage and uproot trees," Chisholm said. "That's always an issue, especially if it is combined with water, if we get a lot of rain that loosens up the soil."

Chisholm suggests having any at-risk trees checked now.

"Winter is actually a good time to care for your trees," Chisholm said, because a certified arborist can spot splits and cracks easier when trees are barren. That helps the arborist get out in front of the problem.

So the next question is, just exactly who is a certified arborist?

Generally speaking, tree experts who are certified by the International Society of Arboriculture are highly qualified. Chisholm adds that here in New Jersey, those who do tree work are required by law to undergo an even more rigorous training program and exam before they are given the state's blessing.
